fly wheel question

[scooterbob]

so dont want to sound dumb ...but the 4.3 and 350 are kinda simular  would a 350 flywheel fit onto a 4.3??

[Jjay78]

as long as it's the one piece rear main seal flywheel, the 1 and 2 piece cranks had different size hubs and bolt patterns for the flywheels

[scooterbob]

how i tell difference??? got one?

[Jjay78]

you can cross check the 427 one to see what i'm talking about, it'll show ya the 2 piece bolt pattern

[scooterbob]

got ya.. ill go out garage and see tomarrow...what boout the one off the 283 ?that 1 or 2

[Jjay78]

that's not only a 2 but more than likely the small 153 tooth flywheel, the one you need is the modern 168 tooth
