I'm trying to figure out my 460 swap, and most people use the 390 flywheel. However, what i'm finding is that the 390 flywheels are 184 tooth and tend to eat starters....where the old 351m flywheel was 176 tooth. Since I'll be using an np435 trans off the old 351m, i'll be using the 351m starter that goes with it.

I have found that the 429 engines had a 176 tooth flywheel, but they and the clutches are big bucks, and this is a low doller build.

I'd like to use the clutch and flywheel from my 351m, but being an externally balanced flywheel, it won't work.

Can i take the flywheel in to a machine shop and have them balance it for an interally balanced setup?

Any easier ideas to my situation here?? Thanks all

 

Even if you could get the weight cut off, the flywheels bolt pattern is different between the two & there would be no way to fix that.

 

really? oh well...I heard it would bolt up..thanks for the info on that then.

 

A shame you didnt post this a couple of months earlier/ I had 2 brand new complete 460 flywheel, clutch, pressure plates and bell housing set ups. Sold them for 200 a piece

 

that brings tears to my eyes

 

Just seen this ad on craigs list in NE PA. bell housing at the end IFS with 410 gears

 

curious...
is it not true that the flywheel from a straight six
is neutral balanced.?

and matches a 351M.?

will it bolt up to a 460.?

i realize no one may have tried before...
because the ring gear would be wrong for starter.

but for the above mentioned...
would it not work.?
