Reaching out to anyone who might know what the best solution is to changing out a tired 302 with a junkyard 5 litre. The dilema is that I know the newer engine carries a 50 oz. balancer compared to my existing 28 oz., my question is; I kind of want to keep my alternator/crank/water pump pulleys in the same orientation, is this possible with a different balancer? and second; the car currently has a top-loader 4 speed, would my original clutch/pressure plate/flywheel bolt up to the newer motor with no issues? any insight would be appreciated.

 

the only difference between the old clutch assembly and new is that the older model assembly (depending on the year)is a 10 inch clutch and flywheel the newer models are a 10.5inch but you will need 50oz flywheel to match the balancer and with the new balancer you can reuse your accessories

 

oh..I see. So i will have to get a 5.0 flywheel(which didn't come with the motor) and a clutch/pressure plate to go along with it? I wonder if the toploader input shaft will be compatable after everything is changed?

 

i think so falcon!!
