keep breaking flywheels!! I have a gmpp 350 290hp crate motor in a '86 silverado with a tci th350 with a 1900-2400 stall. my problem is i broke 2 flywheels around the bolt pattern of the crank. the flywheels i have are pioneer non sfi approved. should I buy a heavy duty one? i'm lost any help would be very helpful!!!
im trying to think of what he said he's deployed so i can't ask him but i think he said something about going back to the gm flexplates. I thought it sounded funny when i heard it but who knows, just throwing it out there
