Flex plate patterns 727

[RED88]

Hello I'm looking at putting in a new higher stall torque convertor but am not sure of if it's a 10in. Or 11in t/c pattern.88 grand waggy w360 727. Any ideas? Much appreciated

The flex plate has two torque converter bolt patters for both the 904 and 727. AMC used the same flex plate base for all of the engines with different weights weights welded on for balancing to each engine. There is a picture of the 727 flex plates in the middle of this post.

why are you putting a higher stall convertor in? A 10" convertor is for race applications a 11" or 12" is more appropriate for daily drivers or towing. they make those with a little higher stall speed but only use if you have a hotter cam. smaller convertors also prroduce more heat than larger(more fluid capacity) also.

Just going with a 11in. 2400 or so stall.
New motor finally going in with rv cam eldobrock intake, headers and holley 670 truck avenger. Hei & E3 sparkers.
Prissy rebuild too nice at this point to beat up off road. That's what my tacos for.
Stalls speeds are fun can catch people off guard
