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

That's what I thought.

AFAIK, 27" tires fits in my stock Dart wheel well but deep down I think a 4.10 may not be right for it. 26" would likely be best.

Once I take the plunge and start getting ready to build this thing, i'll start asking around about converters.

As for pistons...poor tune/crap oils/and missfiring is what causes scuffing, not piston material..lets get over that part already..

I'm not Austin Coil but hopefully this thing will be tuned to a razor's edge.:thumrigh:

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

167's are flat tops with two valve reliefs. See them here.

are the 995 springs doubles with a dampener?

They are indeed double springs with a damper. See them here.
