I have a 418 ls3 that made 456rwhp and 427ft torque!!! Through a a4 with a yanks 3200ss converter unlocked!!! It also has stock 315 rear gear set,and full bolt on as well .I thought it was pretty low my self ,I wanted to see what my motor made.. The dyno operator said it could use a little more timing and that it was lean down low.. I have cnc ported ls3 heads and will have the new tsp aftermarket ls3 heads so I can see the difference in power . The motor runs strong and raced a few low 11 second cars and walk around them on street tires.. I have a set of nitto's nt05r coming for next year.. Just curious to see what you guys think...

Will this thing run in the 10's with a good set of tires? That's what I'm hoping for on horsepower and will be adding the bottle next year!!!! I'm also adding the new prc 250 ls3 heads to see what kind of power she will make but they are going on early next week and then the dyno!!!!

Just put new heads on it and and now it just made 510rwhp and 476ftq!!!! un locked, so hoping with the new power we should be able to get er in the 10's.... My drag radials came in yesterday but it won't be untill next year to see what she will do....

60hp from heads? Thats crazy. Was anything wrong with the ls3s?

Not that i know of!!! the new head design is just awesome , 13* compared to 15*heads. I was able to mill for alittle more compression without effecting the flow numbers i assume.But the smaller runners helped pick up velocity which I believe helped in the added horsepower... it was 54hp but thanks for the extra ..lol :cool:

Nice gain !!!!!! Even on an engine that large it still pays to match the runner
volume for proper port velocity :D

They where either tsp or scogging dickey cnc ls3 heads to the new prc 250 ls3 heads from tsp!!!! I bought them from a guy named Jason on this site and they where new with light weight valves casting numbers where the 821's.... They worked good but these worked better!!!!!:burn:

Well I'm putting a gz vacuum pump , halltech killer bee2 and a set of stainless works 1 7/8 headers.. What kind of gains can be had? I'm thinking around 25 rwhp or so??? I want to get it dynod again but will wait till after Christmas just want to get an idea of what to expect...:cool:
