Friend of mine is wanting to build a 440 stroker. He's asked my opinion on the stroker kits from 440 Source. Forged crank, rods and pistons. Comes with bearings and rings. He's not buying their heads.
Any opinions as to the quality of their stroker kits?

all good parts here.. fit and finish. ordered it balanced and it drop in.. no complaints.

Over 11k street strip miles, still rotating

Thanks guys!

Probably have around 4k street miles on mine and 20-30 passes without issue. It's a low deck 470. Dropped right in without issue.

Using their 4.25" kit for a 400. Something over 3k street miles and their parts have been great.

I ran 8.60’s@155mph with one of their stoker kits for three years. It’s been in a street car for over five years now.
