    Gen IV BBC bolt in compatibility with GMT400 platform?

    Umm, the 454SS had five lugs. I thought they shared the same frame with the regular 1500’s(?). I believe the tow rating had to do with: 1-Engine torque 2-Drivetrain gearing But who really gives a crap about tow ratings for a fun cruiser? The guy wants to build a hot rod. I thought that I...

    OEM Cloth Seat Covers...

    wow! You guys are lucky! I have scoured time and again for replacement or NOS covers/foam for my truck - you would think that there would be a market for this (I mean iirc 1988-1994 got the same material and patterns); The best I have come across are the (ugly imho) covers offered by LMC - but...

    Do shorty headers add any tone and power to a stock l31 with a super 40 2 into 1 muffler?

    Would you (please) be able to tell me if those (factory installed) van exhaust manifolds are the same as the C/K1500 would have received? When I first got this truck, I contemplated getting some headers, but I wanted something trouble-free, and it sure doesn't get any more trouble/headache-free...

    88-94 vs. 95-98 Interior Debate

    I think there are definitely pros and cons for each generation of interior; I had a civil engineering field job in the summer of 1997 where I got to drive a brand new 1/2 ton (very basic; tan cloth interior, 305/auto), and I remember being "wowed" by the new interior; That engine seemed really...

    Truck Value- 88 GMC c1500 2wd

    Cool truck!! (I see you changed the mirrors from the original chromed ones) My grandfather bought an '88 when these first came out; I believe it was a 1500/2wd/auto - but it was the EXACT colour scheme!! The truck I own actually replaced his '88, which was passed on to one of my uncles - as he...

    Driveshaft yoke comparison between 4L60E and TH400

    just a small correction on the highlighted; The 1963-1970 Muncie transmissions all used the smaller output - BUT(!) the 1970 M22 placed in Chevelles(?) had the larger output (and corresponding revised tail housing); The 1971-1976 Muncie three speed (common in 73-76 square bodies) kept using the...

    What carb is this its two barrel i thought that 350's in 82' had Quadrajet

    I am glad to see members here know thier stuff! Those 2GC two barrel cars are the most common stuff from the 1970's - iirc they can rival our TBI's for CFM ratings... seriously. As to the Dual jet, the first version (a Quadrajet with the secondary side unfinished/closed off) was only done for...

    Why no TBI Engine thread?

    I enjoy reading the TBI discussions; I intend to keep my truck stock looking, and running the OEM computer; I have understood that our heads don't flow well, but that goes along with the tiny cam, and measly (cfm size) throttle body. I would love to have more power, but more power requires two...

    1990 GMC

    Congrats on the great looking truck! I say, leave it as-is - in that condition, and that low mileage, I'd be hard pressed to change it. But as others have said, it's your truck :)

    GMT floor mats

    when I started looking into replacement mats for my truck, I hit proverbial roadblocks at every turn - those "Holley" floor mats must be a recent offering, becasue when I ordered ACC mats, that wasn't an option. Now, my truck has had from day #1 (as far as I can remember) carpeted mats; It's...

    93 Factory Radio repair options?

    This was my gut reaction when I read your post. Is there any way you can test another head unit, to see if therein lays your issue? I do not believe that the CDM controlls this, but as I have understood it's the "brains" of the stereo - the functions are separate from the "brains". I recently...

    OEM part number; original vs replacement

    Thanks for your reply, I will remember this when it warms up outside, and I revisit the steering components. This guy is a fourty plus year career mechanic (he was supposed to have retired over a decad ago!) - I have absolute confidence in his assessment of the alignment.

    Unopened cassette

    I have these for a couple vehicles, they are pretty cool; It transports you back to when the vehicle was brand freaking new!

    OEM part number; original vs replacement

    It seems as though I had a misunderstanding that was increased with the very first reply I received. This post is what got me to re-look into this: This one really rang with me, so I looked into it: This is the design of the part #26016461 for 1988-1992 trucks: This is the design of the...

    OEM part number; original vs replacement

    Please allow me to clarify; When I bought my truck it had an original design (and probably the original built-with) idler arm in place; This truck is incredibly low mileage, and has had the alignmnet done, and service parts installed in the past; When I got the truck saftied, it had a...
