Critique this combo - 318!

go with a med/tight convertor=3200 stall and 4.10-4.30@25-26'' tire gear to get into the 12's with this combo.jmo

As for pistons...poor tune/crap oils/and missfiring is what causes scuffing, not piston material..and besides, the stock pistons are softer than hypers and are they always scuffing and smearing themselves all over the cyl wall?
hypers are harder than stock cast, while forged are even harder though they grow more.
hypers are used though out production car engines today along with forged.

lets get over that part already..

now are those 167's domed? so you wanna use a domed piston with a closed chamber?

are we squeezing it over a hill for ???

are the 995 springs doubles with a dampener?
the same ones that I run on my 340 that are '135psi on the [email protected] and [email protected]?
your info is off.

The heads are good, the rest is preference-intake/header brand/ignition etc..
I like solid cams myself but in the range you're talkin or better is a good start.
BTW how it actually runs is a reflection of your tuning ablity or lack of.
