I know it ain't what you wanted to hear. Does your FIL have any friends that do that kind of work? Race guys usually know the difference between someone who's good and someone who's good enough...

It's about time that someone made that connection! Unfortunately, pretty much everyone one of his friends are either dead or long since retired. There is, however, one person my FIL goes to go get some things done. Same guy that did the machine work on my Pontiac 400. Took the guy almost 2 years to get that engine back to me. I don't want to know how long it would take this guy to grind a crank and shave the rods. The bottom line is I don't trust that guy.

Ok, enough bickering. For the sake of progress, I might throw some parts in the dunk tank in the morning. Either that, or I have some wiring and things I could finish up on the Wife's Buick.

I'm still debating what to do about that crankshaft. Is .001" out of tolerance really going to make a difference on a rod journal?
Kinda depends.

The rod bearing clearance "should" be about two thousandths. You'd be adding an extra third to that.

Guys get by with that. Some do it intentionally. Keep in mind that larger oil clearances in general will lower oil pressure, increase the amount of oil flung onto the cylinder walls, (flooding the oil-control rings) and reduce the load-carrying capacity of that journal.

More to the point, HOW are you getting that extra thousandth? If the journal was GROUND with a thousandth of extra clearance, that'd be one thing. Since it's WORN with an extra thousandth, it's likely tapered, and out-of-round, perhaps with a poor surface finish. If that's the case, you'd be building a time-bomb. It'll likely fail sooner than expected--but you won't really know when or how severely until it happens.

Have the crank ground.

When it was me, I told the machinist to "offset-grind" the journals for some extra stroke. I ended up with .040-under bearings, with .020 offset. That means the piston goes .020 up higher, and .020 down lower--.040 extra stroke. Which then means I don't have to cut as much off the deck surface to get the pistons to "zero-deck". This leads to better combustion, less tendency to detonate, and less spark advance needed for max power.

Small update. I called a machine shop WAY the Hell out in NJ to see if they can take my crank/rods and do what needs to be done. Of course they can lol. This weekend is already shot for obvious reasons, so I'll be taking a ride out there next week to drop the parts off.

With that I think it's time I opened the box with the pistons/rods/rod caps.

It's almost two months later... but it's finally here. Behold, my now usable crankshaft.

Now, I need a factory (non roller) cam and all the niceties that make SBC's run. Anyone have a suggest for a good book that goes through building an SBC step by step? I've built two other engines, one being a Pontiac 400 and the other a Buick 300 (SBC derivative). I had books for both.

Following up on my earlier post (quoted above):

I'm looking forward to trying the tuning mods noted here (link below), on my 1998 L31, perhaps the engine will then respond as well as Dad's 1995 K1500 5.7L TBI.

I have never understood why my L31 was so gutless upon throttle tip-in, but after reviewing what others (@kylenautique, @Supercharged111) reported below about "torque management" and "abuse mode", I believe I know the reason.


- See various posts in thread 'Towing with 33” tires versus 35” tires' regarding re-tuning the abuse and torque management parameters
https://www.gmt400.com/threads/towing-with-33”-tires-versus-35”-tires.56164/post-1211110
I* know this is an older thread...

but it caught my interest, especially the tuner. Before I go down a rabbit hole...Please tell me if it can change the engine size. I never was able to tune my HT383E after it went in. NY is a CARB-compliant shitstorm. I do have a 4L70, shorty headers, and hi-flow cats (that almost nobody, like Jegs, would ship to me... ******* CARB indeed) to a JBA single 3", and a Voltant airbox.

When I get her back on the road, I'm absolutely going to tune her. I know there are lots of threads on it, but the fact that our folks in this community are so willing to share and help is amazing. That thread you linked is what got me motivated. Thanks for that.

David Vizard has had some controversies, but I trust him. I have an older edition of this book, and I have multiple other books he's written, every one has been worth the price and more. I like David V. What makes this an even-better deal is that it's published by HPBooks and not SA Design/Cartech.

Note that I have not read "this" edition, (and I haven't read my older edition in years) I don't know if this newer edition covers 1-piece rear main engines, or fuel injection, etc.

I don't actually have this one, but I've got a similar Haynes manual for transmissions that seems pretty reasonable. And again, it's not SA Design/Cartech. Note that I have little use for Haynes service manuals (emergency toilet paper) but the Techbooks like this one aren't bad.

SA Design has a "formula" for their books. 144 pages, not enough to properly cover the subject. Color photos, many times too small to see what they're trying to show you. They'll publish the same photo in different chapters, when they could publish it once at twice the size and it'd be more useful. And most of their books need another round of proofreading and editing. (Some authors are worse than others.) They're just SLOPPY. It's not at all uncommon to pop open an SA Design book and find three or five errors in the first chapter, at which point I get tired of counting them. I've been reading their "AMC V-8 Engines 1966--1991 How To Rebuild & Modify"; as usual there's lots of errors.

And adding injury to insult, they're grossly overpriced considering they're all printed in China. I refuse to buy them "new" at full price. I wait until they've been on the market a few years, and buy 'em used on Amazon for not more than $20. SA Design does have an aggressive policy in that they publish LOTS of car-enthusiast books while HPBooks sits on their asp, publishing few and far-between.


For the record, the Buick 300 is not an SBC derivative. The Buick 300 is a development of the Buick Aluminum V-8 from the early-60s Buick Special*. This started-out as a 215 cid aluminum block, (with cast-in-place iron liners) heads, intake manifold, and front cover. Oldsmobile had a similar version with different cylinder heads, some extra head-bolts, and an optional turbocharger. The Buick aluminum V-8 was dropped at the end of model year '63, replaced by the very-similar "Buick V-6" with an iron block and heads, but retaining the 90-degree bank angle and most of the architecture of the V-8. The all-aluminum V8 was also developed into an iron block/aluminum heads 300 (1964) and eventually iron block/iron heads 300 ('65) which then grew to a 340, before becoming the long-lived Buick 350.

By 1967 or so, Rover of England bought the rights to the Buick Aluminum V-8; it was manufactured in England for Rover cars, the Land Rover series of SUVs. Some specialist sports cars bought engines from Rover (TVR among others.) The English couldn't/wouldn't build a decent engine, they had to buy and redevelop an American design. They did do a bunch of redevelopment over the years.

What's really funny is that Ford purchased Jaguar/Rover, so what used to be the Buick aluminum V-8 eventually became a Ford product before being discontinued. I've said it before--the best engineers that Ford has, work for GM. This is similar to Chrysler producing and selling "Ford" V8-60 flatheads in the late-50s in America via their "captive import" from...Brazil, I think.

Jack Brabham of Australia partnered with an Australian company (Repco) to develop the Oldsmobile version of the Buick aluminum engine into a Formula 1 race engine, with some success. He won the championship in '66.
www.whichcar.com.au/features/the-repco-brabham-miracle



None of this has anything to do with a Chevy V-8. The Buick/Olds/Rover engine has the distributor in the front, driving an oil pump machined into the aluminum front cover, and the distributor gear on the camshaft overhangs the front cam bearing. These designs were later carried into the Buick V-6 and the V-8 300, 340, and 350 "small blocks", and also the similar-but-different "Big-Block" 400, 430, and 455.

*The Buick Special of '61 was considered a "Senior Compact" car, along with the Pontiac Tempest and Olds F85/Cutlass from '61 to '63. All three of these "Y-Body" cars were developed from the Corvair unibody, but had front engines instead of the 'Vair's rear engine. So you could say the Buick Special was developed from a Chevy, but not the engine powering it. The three technologically-advanced, daring, and troublesome "Y-body" cars were dropped like broken rubbers for the '64 model year, replaced by the ordinary, dull, yet hugely-popular "A-body".

The south american V8 60 would be a Semca IIRC. They actually added Hemi heads to it later. The French military also used the larger flatheads and cast them into the 90s excellent blocks for hot rods.

The A bodies were so popular because they ride and drive so nicely compared to a unibody car. Very comfortable cars to drive and ride in for long distances. They also had decent handling, acceleration and braking for the time period.

So, I read the reviews and scrolled through the previews for both of those books. The first link is a book published in 1991 and was written before my engine was even manufactured. Thanks, but not helpful.

The second link is a book published in 1999. Again, scrolled through the preview and this book MIGHT have the info I need. I see it's also got info about rebuilding carburetors. Seeing as I have TBI, this too might be a bit outdated.

I'm spoiled, you see, because the book that I used for the Pontiac 400 rebuild was written specifically for that engine. I used a Factory Service Manual for the Buick 300 rebuild. That FSM was well worth the money. Very detailed.

I guess the assumption today is to just use the Lying, Spying Google for everything and the info magically enters your brain (much like the Matrix).

I dunno, I feel like if you've built one cam in block V8, you've pretty much done all of them. Just look up the torque specs and clearances.
