Buying the correct torque converter

[JamesF]

I ordered a 10417 torque converter from B&M thinking it was the right size but the hole pattern is different than the one I took off of the car. Date on 727 and 383 is 1970.

I used them, gave them the specs I had and hand built and shipped quickly. It was reasonable too and fit was great and even better works well with the setup!

Call John Cope @CRT and give him your specs. He uses PTC and builds to suit. I have two, and will use him in the future as well.

Ya you can use cope or a&a trans. Or just go directly to PTC

There are 2 different factory converter bolt patterns. Buy a B&M or aftermarket flex plate. Or if you know a good machinist have them redrill it.

The 10417 is an 11", same as the 383HP would have come with. If it wasn't originally a HP it would have come with a 12" converter with a different flex plate.

The 10417 is a 10" I think but I need 11 1/8 bolt pattern.

As you can see from the B&M picture, there are 2 different bolt circle diameters AND the larger size bolt holes for the Hemi (or some aftermarket) 7/16 bolts. The B&M plate pictured covers them all. Beware of the 1 offset lug too & which side of the plate goes toward the block.

Got mine from 440 Source, Not SFI and the only real difference is the $10 sticker as far as I can see.

Technically it's a 10 3/4" and has a 10" bolt circle, the 11 1/8" bolt circle is an 11 3/4" converter. A simple flexplate change makes the 10417 work for you.
