Questions about 460 conversion......

tilted78f150 · Apr 10, 2005

Okay. I am puting a '77 460 in my '78 F150. I have some questions, hopefully you guys have the answers!

1)What fly wheels can I use? I am keeping the 4sp that was against my 351M.

2)And what starter would I use for that flywheel?

I think I have everything else figured out, but if anyone has any tips or hints,that would be awesome. [-o<

if you can find as 460 flywheel a 390 can be used. if i remember right just use a 460 starter.
you do know you'll need mounts for a 4x4 for the 460. there is no factory 4x4 460 mount the site below will help on the swap
www.LandLproducts.com can also help.

here is what i found out. any 360-390 flywheel will fit any 460. but 86+ have a diff. balanece. So your 460 to work with the 390 flywheel will need to be pre-86 to balance right.

If 86+ a mech. shop should be able rebalance it for you fairly cheap.

I read some place the 360-390 use a 164? tooth count and 460 is 185? count. but either count will work.

The ones i've been around using the 360-390's didn't say what count. I just know it was whatever count flywheel they found first.

When I swapped in my 429 (same as a 460 but with shorter stroke) I used mounts from L&L. It was 12 years ago, but as I recall I used the flywheel which was already on the 429, but changed the tailshaft to fit the tranny. Then again, mine is a C-6 where yours is a stick - so this may not apply. At any rate, the difference will be AWESOME! Have fun! (That old 351M will make a good fishing anchor - which is about all they were good for in the first place!) <_<

One more thought - I also changed out the oil pan to one from a van, also used the van dipstick & tube. While I was at it I also put in a high volume oil pump.

i'll tell you this whole conversion has been an adventure , the only major problem i came across was that you need to use a 302 pilot bearing not the one for the 460
(THAT SUCKED) thanks for all the info i will post pics when its finished !!!!!!
