Anyone fit sm465 with the original brake/clutch

I’m trying to fit a 292 with sm465 into a 1951 Chevy suburban. The problem is the clutch fork is so long it runs into the pivot point on the original brake/clutch setup. It’s at least 2” too long.

Curious if any of you guys have had luck keeping pedals in the same spot?

My thoughts are maybe if I cut clutch fork after first notch maybe I can offset engine to passenger side and maybe have enough room.

* moving engine up doesn’t help since it would still hit brake arm.
* moving engine down would have to be close to 4 inches down. That would need notching crossmember for harmonic balancer, oil pan clearance on steering linkage, fan issues.

Thanks for any advice.

Re: Anyone fit sm465 with the original brake/clutch

Are you running a cast iron V8 bellhousing and the 51 Clutch fork?

The late model clutch forks don't fit in AD trucks with stock pedals.

My 48 with the 250 in it has a cast iron truck bellhousing and a 48/53 clutch

I deleted that photo because although it is close it may not be the correct Truck pieces.

This would be the correct Chevy truck clutch fork setup eBay item number:256793482583

Note that it won't stick out of the bellhousing very far.

It helps if I upload the image the first time.

A better image of the 48/53 clutch fork. Could be 54 and 55.1 too.

Thanks for the reply. Yeah I’m using a cast iron bell housing looks like the same one as my v8 has. I’m going to move things around as much as I can next week and see if I can come up with solution. I’ll let you know. I was really hoping to keep old pedals down there.

Remember that the SM465 has a larger od on the bearing collar than an SM428.

I didn't think of that one last night but you have to use the cast iron bellhousing that came with it.
