help flywheel question

[jonsranger]

hey guys, i got a 73 302, and im trying to get a flywheel, i bought it off a guy here but i cant remember who it was, but any ways, i know you have to match up the crank, harmonic balancer, and flywheel so there wont be vibrations, the harmonic balancer i have is about 9 lbs or so, i am assuming that that would be the 50 oz balancer, but how do i make sure that it is right for the engine, where are the numbers to see what crankshaft i have, i do not want to take the engine out and the oil pan off. the engine also came with a flexplate would that matter in which balancer is used?

thanks
Jon

I'm going to say 28oz, but don't take my word.

ok i found out that it is a 28 oz harmonic balancer. now i need to find a flywheel, all of the local autoparts store dont have one, and the cheapest one i found that i can order through the local performance place is like $275.
is there anyone who makes one cheaper?

Take your pick.

Aluminum or steel

$89-$270+ Depending on model

Also, since it sounds like you're going manual tranny and the donor engine was an automatic, don't forget to change the carrier bearing in the back of the motor. I think automatics and manuals are different sizes.
