flexplate and converter question

[mopar367]

i have a internally balanced 440 im building. i need a flexplate and torque converter. will a flexplate off of any 727 trans work? and will a 318 converter work ? or any 11 inch converter with no weights on it?

Short answer, yes. The flexplates interchange. There are two torque converter bolt patterns. One is for the stock large low stall converter and the other pattern is slightly smaller, and used on the majority of converters. Many aftermarket converters use the smaller bolt pattern too, but with larger 3/8" torque converter bolts. I think stock converter bolts are 5/16".

THERE ARE 6 BOLT FLXPLATES WITH 5/16 CONVERTER BOLTS AND 7/16 BOLTS AND THEN THERES 8 BOLT FLEXPLATES WITH 5/16 AND 7/16 BOLTS.
you'll need to drop your trans. and see how many crank bolts you got 1st. then match up your converter with either 5/16 or 7/16 bolts. hope this helps.

I thought only the Hemi and aftermarket cranks used the 8-bolt crank?

It gets strange. Most are 6 bolt, but in the crank where another bolt wood be is an indexed space, don't know hemis, but every sb and bb I have seen is 6.

Call Turbo-action, Paul will tell you.
