I have been an avid reader of the boards for the past like 2 months just dont ever post cause i dont know much but i thank you guys for teaching me soooo much. THANKS!!!
BUt now i got a question i havent seen answered in teh search anywhere. First one is port and pollishing the heads and the intake what exactly does this mean cause i would like to do it cause it seems pretty popular, and also a stall converter i read some things of what kind to get for certain cars but no idea what exactly does so if you guys could hook me up with answers i would love you all even more (dont worry i got a g/f haha) thanks guys

Aight Mitch, it's like this.

Port/Polish the intake/heads/exhaust helps to eliminate the casting 'flash' (roughness) and help air enter smoother, and quicker. More air in + more air out = more hp.

Same thing for the intake, and exhaust manifolds.

a stall converter works like this -

Imagine a stall converter with a stall of 2000 rpm.

If you floor it, your engine will rev to 2k, then the tranny kicks in (yes, mucho simplified, but that's basically it).

Stock is like 1500-1700rpm (?) It really depends on where your engine makes power. You want your stall speed to be about where your engines powerband really kicks up. a 2200-2400 would be good on a well tuned, mildly modded 3.1.

 

If im putting a shift kit into my automatic do i really need a stall converter then?

 

you dont need a new torque converter but you could if you want
and i would also recommend a tranny cooler with that new shift kit
