Is this a good block and rotating assembly to start with?
I am looking to get an almost complete engine from a guy pretty cheep.
Going to give him 100 and some old headers.
Was wondering if it was a good block and all to start a decent build for my truck.
Nothing too extreme. Still want it streetable and all but want about 300 to 350 horse.
He said it was from the mid to early 80s and I believe from a truck.
Cant seem to find anything about the casting number.
Just want to make sure it is not a smog engine or anything. I want some decent power.
When it comes to trucks everything between 1977 and 1987 is a low compression - low output smog motor, but that's mainly due to the heads and cam.. which can be changed pretty easily. If it's a 4bbl 351 from this era it's the 351HO and that's a good platform to build upon, swap on some better heads and a full exhaust system and 300hp isn't a problem. If it's a 302 you're gonna have to work a bit harder, it'll need a complete HCI combo to make decent power. In both cases the stock rotating assembly is more than capable of supporting this power level so nothing extra or even that special needed there, if you're rebuilding it just get it to stock spec for a late model engine('87+) to give it about 9-9.5:1 CR with most available cylinder heads.
Basically what I was asking is if the stock assembly could hold it and if the block was alright.
Sounds like it should be alright.
I am changing the heads and everything else.
I read somewhere that it was a roller cam? Is that true?
Not looking for anything stock. I have my stock 79 with only 112 on the dash.
(3rd owner).
Looking to slam the truck on the 20s I have with some sattin black and red interior.
I read somewhere that it was a roller cam? Is that true?
Roller cam didn't appear in truck engines until 1992, though all blocks cast from 1987 on(E7TE casting number) will accept the factory roller cam assembly even if the motor didn't originally come with a roller cam.
Yeah compromises have to be made. It's no big deal in the long run.. you can still get roughly the same power level with a similar spec flat tappet cam.. at a 1/3 to 1/4 the cost.
