Stroke with only Pistons and Crank?
So here’s my .02 worth after doing this on my 340 last year.
I took apart my original 340 in my dart, hadn’t been touched since 1983. I had some wall taped so a bore job was needed. Might as well resize the rods and add new bolts. New bushings on the small end because they are 50 plus years old. Grind the crank and balance the whole thing for the new pistons.
Real life use says I don’t need forged pistons, it’s a mostly stock car. Once I priced everything out it was cheaper to go with a stroker kit from Scat. It came balanced and Ronnie at RAD machine said he likes their stuff.
It was a hundred bucks cheaper to buy all new parts and then I resold the original steel crank, 340 rods and the TRW std bore pistons that I installed in 1983 and recovered $400 towards my purchase.
The kit uses stock small block rod length 6.123” and now it’s a 372” 340 with stock manifolds and exhaust it’s a nice package in my car.
