383 1 Piece Rear Main Flexplate, help me find one

[sled_dog]

I'm having a hard time locating a 1 piece rear main flexplate for my 383. It is externally balanced. I need one to get my balance work done. Summit's new site is useless.

This is the only one I've found so far. Not liking the $85. I don't need a freaking SFI approved one, its just a rockcrawler.

$40 is sweet but I don't know if I can wait that long on shipping. Have to decide quick. I'll probably end up buying one through the shop doing my work.

ALL 1 pcs RMS flywheels and flexplates are externally balanced.

dude 1 piece 383 cranks are a dime a dozen. Eagle makes them almost as much as they do 2 piece ones. Not all 383s are cut down 400 cranks, aftermarkets do make specific 383 cranks you know. My crank cost me like $175, what an amount of money to blow

 

[beater_k20]

well 400 were gone after 80, so none were ext balance

and all 400 are two piece

how do you have a one piece 383 crank ?? and why ?

this is very interesting

actually no, its not.

am i missing something ??

YUP!

wish i had the cash to just waste like that,.,. hummm.,.,.,

actually, its not any more expensive to build a 383 off of a 1pc RMS block anymore, crank prices are comparable.

in 85 when they ditched the 2pc RMS, they also lost the ability to easily internally balance the engine as the 86+ sealing surface does not allow metal to be added or removed, so the flywheel/flexplate have to carry the weight.

I just bought a balance plate, thanks guys.

And the reason for ther 2 piec block for me is factory roller camshaft setup and I had the block.

if you're running a 1pc RMS crank, not only do you not need the balancing plate, it physically wont fit, the bolt circle is different. you cannot buy a neutral balanced 1pc RMS flywheel or flexplate, they are ALL counterweighted.

Yep Beater_K20 is correct. When the 1 piece RMS came out all SBC's were externally balanced on the rear of the crank but not the front. I built a 383 using the 1 piece RMS and when i had it balanced it was a minimal amount of work to balance it using the factory flexplate.
