thanks, not much internal wise slightly shaved heads, double valve springs, a rebuild, and remapped chip (done about 80,000k before i did the manifold) don't have any dyno sheets but it has alot better throttle response and torque. it also has rebuilt trans with kevlar belts corvette servo and stage 2 shift kit built for 800hp worth $3500, i was planning to turbo it but unfortunately she'll be up for sale soon cause need a more practical family car according to the missuse

While youve done a fantastic job there, thoses runners seem mighty short. 10" is usually as short as one normally goes. Those runners are mad for turbo and side mount super chargers though. That will allow you to run a ver large cam though.

I was thinking exactly the same thing.

I'd like to see proper side by side dyno comparison for that one. Better throttle response maybe however I'd be amazed if torque was any better what so ever.

throttle responce may feel better but back to back there will be a torque loss down low and a hp increase up top, this design is nothing new and a few i have seen have tried them and lost to much down low that they went back to standard and sold off the custom one.
Having said that you did some nice work fabing it up would be great for turbo or supercharged setup.
