I am having my engine built on the mild side and I was wondering if you guys had a guess on what kind of horsepower it might put out? I am using my stock l98 heads, they have been ported and given a 3 angle valve job, also new performance springs and roller tip rockers. ZZ9 camshaft, Mini Ram manifold, headers, Bored .30 over making it a 355, Forged pistons bumping my compression up a little. I wish I could afford better heads and get a bigger cam but its not really in my budget. I will probably spray it later on to make the horsepower I really want. I hope this is good enough set up to a least be quicker then any LS1 on the road.

 

Faster than any stock LS1 ... Hydraulic roller lifters and cam would help a lot .

 

I doubt you're but you should be able to run with most of them that are mostly stock.

Your heads are holding you back BIG TIME. They're your weak link right now. Assuming of course that you have a good exhaust on it.
