331 Stroker Kit question

If you have to buy a crank already, then I see no reason not to buy a stroker crank. I myself went through the same thing a while back with my '93 mustang. I ended up buying a 331 street fighter kit from probe and I loved it. Erik D. '94 white lightning

I built a 331 stroker from scratch. Just remember that there's a LOT more to it than changing the rotating assembly if you want to maximize performance (heads, cam, valvetrain, intake, etc, etc). If not, then just make sure that the new crank has the same balance as your damper and flywheel unless you want to replace those also (ie 50oz or 28oz). Without better heads etc the added volume will not fill as well and you'll run out of breathing capacity sooner. The stock heads breath pretty horribly supplying 302 inches so you can figure what they'll do trying to supply 331.

I would ALWAYS balance the rotating assembly on a stroker kit. When I built my 393 stroker Windsor, It was supposed to be used with the stock 28oz balance. If I had tried to bolt it together the motor damn near woulda flown apart. the balance was WAAYYY off and a ton of weight (comparitively) had to be added. I did ask if maybe we ended up with a crank for the 50oz balance and the balance shop said, "no". I bought the kit from CHP. Nice price, bad balance. Just goes to show you always have to check everything twice and to assume that if the manufacturer is gonna screw one up, it's gonna be yours.

I second that. Though my rotating assembly was "balanced", I am very happy I had it precision balanced. It was close but not as good as it should be.
