I am looking to do a 350 build for my K10 in the future sometime. I will probably do a 383 kit with vortech heads. can anyone tell me what the best block would be (if any is better than others) for my build, like an engine number or something?
-
casting numbers that end with 010
-
ok, what makes these better than other 350 blocks. i looked it up and the 010 says it is a 350 put in cars trucks and vette's from 69-79 so what is different? just want to learn more about all of this
-
Different in the truck versus the Vette, vs the car.. Nothing.
The number means that is a good block, all of them are identical blocks.
-
Find a roller 350 vortec engine.
-
I was wondering about this.. if the roller 350 just means it has roller lifters.. why cant you just put roller lifters in an older block? or would that not work? or is there other things different too?
-
A roller block is already setup for roller lifters. Its cheaper to put roller lifters in it, because its setup with the spider in the middle that holds the lifters in place, otherwise you'd have to pay a bit more for the lifters to put in a non roller block. Someone help me out here, Im confusing myself.
-
:D I think I'm in the same boat as choptop.
Retro rollers are $. If my bottom end wasn't a low mile rebuild, I'd have gone complete roller motor. No reason not to. If your looking for a rebuilder, I'd lean toward a later roller block, esp. if your looking for Vortec heads. I think they're '96-2000 (complete 5.7l "Vortec" engine), don't quote me on that though. (Vortec heads are 062 and 906 castings, iirc)
Be prepared to run an electric fuel pump
Short of pulling the intake, I'm not sure how to verify that it is a roller block. (maybe someone can fill me in) If I'm not mistaken GM still sells flat tappet crate motors, so don't assume anything.

If I remember correctly, 87-92 350's that came in F-body cars were equipped with a roller cam from the factory.

Back to the original Q.

awesome info guys, thanks. Yea i forgot about the metal piece that holds the lifters in correct orientation. Thanks guys!!
-
Don't forget about the cam walk. A roller cam engine has to have the cam retained somehow from walking. The factory roller blocks are all set to rock n roll. As already mentioned $$$ for a retrofit roller set up.
-
ok well i guess that is that.. I am going to find a 96 up vortec longblock if possible that needs rebuilt and I am going to make an awesome 383 vortec for my truck, then I am going to try to find a donor vehicle with TBI and put the whole TBI system onto my 383 vortec. How does that sound?
-
Sounds like a plan.
