I have a 69 340 Ive been running in my challenger for 7-8 years I will soon be swapping for a magnum 360 stroked 408 soon to be out of the local engine builders shop. I am trying to get my pre-planning sorted out here...hence a question for the group...
Can I use the same flywheel from my 340 on the magnum block 360? (internally balanced) If so, I would then assume the bellhousing will also work?

Thanks for your help

Given that your Magnum has been converted to internal balance, you should be able to use your LA flywheel. Amusing it is, in fact neutral balance itself.

Bellhousing should be fine as well.

But you should dial the bell to the different block.

Yes I plan to dial the bellhousing, thanks for the help!!
