I noticed BB Chevy pistons had the right bore for a 383 but wasnt sure if it would work. I can hear my engine builder now...lol.

I would love to hear more about this if some has tried it.


I have the Enginemasters crank with 6.7 rods and 1.32 pistons. The 1.32 pistons can be used with a number of different stroke/ rod combos. works wit ha 3.75 stroke , 3.9 stroke and a 4.25 stroke. I'm thinking of upping the stroke on the 383 stroker I'm doing now to 4.25 , just need a 6.535 rod.

The one issue you may have is the valve reliefs on the BB chevy piston may not work with your wedge head mopar configuration , might be easier to just buy a mopar piston.


running up my post count some more .
