tpi to lt1 power???
I search already maybe i'm to dumb but I can't see were anyone has ever stated the numbers on power gained or e.t. improvement going from stock TPI on a stock motor to lt1 intake. Does anyone know either number? Do you have to switch heads and cam for good gain? will stock heads keep up with lt1?

roughly 20+HP
-15 FT LBS TQ
and your RPM power band is moved up from the 4,500 to the 5,000 range
switch the heads/cam and you'll see huge improvements over stock
with the LT1 intake, but stock heads should be just fine if that's what your asking?
