Differences in 340 and 360 crank flange bolt pattern

[Heywodja]

I have an internally balanced 360 crank and will be installing a new flex plate and torque converter.

I need to know if the internal balanced 340 and 360 share the same bolt pattern on the flange.

Thanks

OEM cranks Yes.

All A, B, and RB engines share the same crank bolt pattern.

Hemi and some old truck/industrial engines are the exceptions.

Pretty sure my engine is not a Hemi... lol

The cranks either have symmetrical or offset bolt pattern...

Then the converters either have 10" diameter or 11" diameter bolt pattern to attach to the flex plate...

Figure out which crank bolt pattern you need and then match the bolt pattern for the flex plate.... Click on each of the top 4 links on this page to get either one....
