I'm trying to remember when and which version Mopar racing block came with the 4.84 bore spacing, I'm thinking around when Darrel Alderman started driving for Mopar and those blocks had the distributor in the rear like BB Chevy blocks do, special block, special heads and so on work
I can't remember the names of those heads either whiney


Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
