12 second junkyard 318

I have a word for your post.... Parragraphs!

For a low 12 second run at the 1/4 mile track, 360 heads become a needed evil, which aint so evil at this point of the game. Alloy heads need not apply. (AKA ALuminum.)
I seriously think the 360 valves in the teen head will do it well. At 1.88 - 1.60 in size, it is plenty.
Also, the factory distributor is all that is needed. The addition of light springs is all you would possibly need.

MoPar used to have a "Tip's" section detailing the parts needed to run a "bracket time." For 12's it was there "231" cam. For the low 12 second bracket, they recomended there "346" mech. cam.

Alot of the build is dependent on actual useage. Track only or not.
