Changing motor plate
« on: December 25, 2020, 10:36:49 AM »
Is there any way to drill a motor plate to a different pattern without starting from scratch? What about bbf to Chevy trans? Any ideas?

It would depend on what thickness plate you were starting with and any bolt pattern overlap. If thick enough you can duel pattern using countre sunk cap screws. We have a 392 Hemi with a powerglide.  :)

I would almost bet advance adapters makes a BBF to chevy adapter that you could buy and bolt through your Ford holes and use the chevy side as a drill guide.  If you're looking to use a chevy trans behind your Ford an ultrabell is the best way in my opinion.

I had a Chevy motor in this and a Chevy powerglide. I don't mind changing the Bell to fit the Ford I was just curious is there was a drill guide to go from Chevy to Ford to not have to build a new motor plate just pop in the new bolt pattern but keep the crank shaft centerline

Gotcha.  Advance adapters may have an inexpensive adapter you could use that would do just what you want.  I think I've got a pattern for a 351 I could overlay and cut a piece of aluminum with both patterns.  But I'm not sure which 351 I have or if it's the same as what you have.  You'll have to school me on Ford stuff

Yeah if it's 351 Cleveland it's big block pattern of it's 351 Windsor it's the smaller sbf pattern.

302/351 clevland uses small block pattern, the 351M/400 tall deck Clevlands use the big block pattern.

I have mounted them in the mill and changed to different engine combos on an existing motor plate
