That 318-2 dime rocket

[Mark Yacavone]

H.O.D. ,One thing I can say about Billy, after about 40 years, is he can speak for himself, so I'll let that last one pass.

Couple tips..
1, There are about 2 or 3 of those combos out there. I don't think any of them frequent this forum, so I suggest you do a little research , and track them down. I'm sure they'll be glad to talk to you.
2, When going back and forth between a 2 bbl and a 4 bbl. ,you're going to want to change a lot more than just the carb and intake.

The 318 Four Barrel is very good @230HP

My boy held the record a couple different years with it
and won his class @ Indy on a modest budget (ran 1.+ under
when he needed)

But only legal in 78 up 318.

Two barrel was under index but never very great for us
