There are a couple guys out there that do very good work on these engines. Marc being one of them.
Pete did the heavy lifting on my car. Again, doing it piece meal, I'm sure I've got more than the 10 or so grand these guys all hover around. I'm 451 at the wheels. Wife doesn't like the car anymore, can't wipe the grin off my face. |

I just posted a .pdf on my thread re:Tuning the LT5. You will find a comparative dyno sheet there that shows the diff in hp and torque between three successive upgrades that I did on my car. Should give u a benchmark on the Cost/Benefit of each. OTOH, there are some that don’t care about cost/benefit. We just want to eek out as much power as possible.

drove my car, got out, hopped in a ported car that made 440 wheel. night and day. no downside, all up. If I had the money I'd have it done already

Thanks guys- this is what I'm looking for. From what I'm reading, a 4.10 gear, porting the tops and headers are a low risk , super high (fun) return on investment.

The downside is having to buy rear tires more often.

I will agree with the 4.10s making the car fun. but my car is still not ported and honestly, no plans to port any time soon
