I've got a 351W with an auto transmission. I'm swapping in the t18 from a donor 300. The 351W is a '90 and the 300 donor is a '89.
My plan was to put the flywheel off of the 300 on the 351W in place of the flexplate., but I've been doing some reading and I believe that the 300 flywheel has the wrong weights for 351W.
Can someone verify that this is true?
What flywheels would work for what I'm wanting to do? I have some flywheels off older (late 60's,early 70's) 302. Will they work?
You need a 28oz flywheel for the 351w, the 300I6 is neutral(zero) balance. Pre '81 302's were also 28oz imbalance so one of those would work as long as it is the right diameter.
