A-500 A-518 with a440

[jos51700]

There are adapters out there to adapt small block bell housings to big blocks. Is it possible to build one of these transmissions to live behind a mild 440 in a lighter street car that will never see slicks?

I want overdrive behind an automatic big block but want to keep it all Chrysler.

Yes

 

[RustyRatRod]

Sure. Why not?

What parts would it take to build an A500 to hold up to the torque of a 440?

I think its J and W who make a racing bell for the 727 that bolts to the pump bolts. Same pattern on the 518. A stock 518 will hold up to a 440 just fine. There isnt really a good way to adapt a small block trans to a BB without sawing off part of the block due to the starter location difference.

I wouldn't do it.

jas0162 is right. Around 2004 we did a 518 (P5249166 if you can find one)with a JW conversion bell and stuck it behind a 500 CI big block.
Trans tunnel work is required and cross member. Also a 10'' converter will be needed as a stock converter will not fit inside the JW bell housing. It can be done. Would I do it again ? No. Silver State offers a good overdrive kit that works well and much easier to install.

It may be easier just to install a overdrive unit.

I wanted to do my 88 D350 pickup and have priced all options out as far as new parts go.
518,Silver State or the Gear Vendor when all said and done it ruffly in the $4000 range.

I cannot advise you specifically, but remember, the "some years" Cummins used the same basic trans--which is a 727 in "old speak" behind the diesels. 47-48RE is "in reality" a beefed 46RH/ RE

Where are all the 904 fans to chime in on using the A500? Ferris? Anyone?

 

[Darter6]

Sure, A A500 is a tough tranny too.
Works as well as anything else.
