So why does the goodwrench motor only have 190HP when my motor has 210?

[TylerZ281500]

TBI with the ultimate mods, gutted pressure regulator with a tpi pump and an inline regulator, had that setup even before the swap.

i used the 350 block that was in my truck and the head gaskets blew, compression was getting low on it when it was a 350 and i foun the rings were shot, pulled the bottom end and the crank was toast, the engine was replaced by your 190hp crate motor about 50k ago. decided since i needed a new crank and stuff id go 383 so i started shopping around for my parts, collected them for awhile, head gaskets blew again and i pulled the motor and did all the stuff knowing headgaskets werent gonna fix it again.

the block needs to be ground a bit to let the larger crank clear.

Ugh - you're saying the factory crate blew it's head gaskets and munched the crank in less than 50,000 miles?

yeppers and i never beat on the truck. that was the replacement that went, i bough the truck with a replacement crate motor and the paperwork was legit and all that, dont know why the original motor was replaced either.

Unreal. It was still under warranty, wasn't it? (3/100,000)

Do you think the PO let it overheat or f'd it up somehow?

 

[TylerZ281500]

no signs of any overheating, it should have been under warranty but since it switched owners they wouldnt honor it for some reason. i know a few people who have had crate motor troubles. the only ones we havent yet are the more performance oriented ones like the zz4, 502, ramjet motors etc. i will only build my own engine fro now on even if i have to teach myself in the process, theres only a select few friend and neighbors that i will let touch anything driveline wise on any of my vehicles.

Well...that's kind of disappointing.

a hair but i got to build a 383 and then snap my truck in half

True, true...

That 190HP crate motor according to Summit makes 260HP with headers and a good manifold.

What's the "rest of the story"?

I doubt the stock ECM map and TBI can flow enough to support that.

Also, are you talking about this? :

Or were you talking about the "basic" one: http://www.summitracing.com/search/...-d-base-195-hp-engine-assemblies?autoview=SKU

The second one is for pre-85 cars. No-go.
