Sorry I haven't commented on your mods, but truthfully I haven't got much into mods on my C4. All those mods are sound improvements because of the limitations of the TPI setup on middle 80's Vettes. To me, it sure sounds like you are the right track without having to go into the engine to boost horsepower. The main formula for horsepower is cylinder pressure. The more gas and air you can squeeze into the cylinders, the more hp you can generate. The mods you are doing help produce cooler, denser air, which equates to more air. Another mod that I want to try is a bigger bore throttle body, which you might consider. Good Luck!!

Actually, the reason for the screens is to create turbulence. Turbulance helps combustion which helps economy. Just a small tidbit for you.

Mech259, That's what I was thinking no reason for filtering that far back. also in another post someone mention pollishing the intake ports on the manifold and heads. I was taught to leave the intake semi pollished so it would mix the air/fuel better before it entered the cylinder. pollish the chambers and the exhaust ports after you remove the emissions humps(Ford). Breathing is a big deal for ICE's. Does this sound right? it always seamed to work pretty good.

Porting and polishing cylinder heads always helps performance. The more air/fuel you can get in the cylinders and the faster you can get it there helps on cylinder pressure and makes your engine breathe better. But this is intrusive work and porting and polishing is very time consuming, hence expensive. It is all done with a grinding tool by hand most of the time. Leave it to the proffesionals. LOL

IN RESPONSE TO WHAT A COOLER THERMOSTAT DOES (FROM WHAT I UNDERSTAND) IS IT FOOLS THE COMPUTER TO STAY IN CLOSED LOOP MODE LONGER WHICH MAKES IT RUN RICHER AND GIVES MORE TIMING ADVANCE. I'M NOT SURE ON THE SPECIFICS OF THIS BUT I KNOW IT HAS SOMETHING TO DO WITH THE COMPUTER AND HOW IT COMPENSTATES FOR A COLDER ENGINE THAT IS TRYING TO WARM UP.
