the motor I have now is a stock lo3 so anything is a upgrade.

I need an honest opinion. I want to build a 350 (Budget) a man gave me a set of (good) camel humps off of a corvette for it (with bracket holes) what do you guys think. this is the bottom end this is all I know about it I bought the block made like this:

Fresh 40 over 350 block 2 bolt main with arp main studs
Bored and honed with torque plate, decked
Brass freeze plugs with clevite cam bearings
Cast crank turned 10/10 with clevite main bearings
Rebuilt rods with arp wavelock bolts and clevite bearings
Speed Pro Hyperutectic flat top pistons with speed pro moly rings
Assembled with all clearances checked
not a super fast race car just a fun DD anything near/close to 300hp is fine

talk to me!!!!!

 

Vortec heads will give you a lot lower compression, better driveability, and flow a lot better than any other gm oem head. They come off of the '96-02 tahoe and trucks.

 

You can get 300 horse on that set up but you'll be pushing streetabilty on a stock stall. I'd imagine you need a pretty high lift cam if those heads aren't machined.

 

hey, quick "?" IF I get a fresh set of Vortecs to go in conjunction with this bottom end I guess what I'm asking is what I can expect as far as (CR) and octane, streetability,horsepower, Daily driver?, detonation probs, Quench, remember the block is decked. it will have a carb. and of course the block still needs: intake, carb, oil pump, headers, oil pan, dist., cam, double roller timing chain, lifters, and rods

 

rumor goes.... vortec heads.. lt4 hot cam and 1.6 rr equals to about 400hp....

 

on a stock bottom end

 

"Driveability issues?" or should I say on premium gas or rocket fuel?

 

No? with that combo it should be 89 probably, and that would be fine.
