Convertor reccomendation?

[bmoparmofo]

Hi, I have a 383 .30 over 10 to 1 compression, 495 lift cam, 268 duration, its in a 69 charger with a 727 w/ shift kit. I havent decided on the suregrip gear yet. I'm leaning towards a 3:91.Just thought I'd get some ideas for the convertor and also the flex plate. My 727 is in the shop now, I might actually get to start this thing this year!

if you do a search for a converter more than likely you would find that people recommend the following places: PTC, Turbo Action, Dynamic, ATI, Cope/CRT.  PTC and Turbo Action come highly recommended in what I have been reading and asking around for but you need to know what gears you'll be running too    So when you do call them up they can set you up.

Sounds really close to my combo.

I've got a 383 at about 9.2:1 494 lift with a 727 and 3.55 suregrip. I called Cope Racing Trans and he spec'd me a 2600 stall PTC. Haven't gotten it all together yet but you should probably aim somewhere around there.

Your combo does sound pretty close.I dont have much of a clue as far as 10 inch or 11 etc..anyone have some insight?

The turbo action 11in hemi converter would be a good choice with that combo

Thanks for the info, anybody here running one of them?

Also how much difference is there between this and the stock convertor? Its a original 383 2bbl car. Is this the difference worth the money? Thanks again.

I recommended one for Kam Cuda....he has it in his 70 Cuda with a 408 stroker. Lots of tire boiling fun !

Big difference from a stock 383 2bbl converter. Probably in the area of 1000rpm in stall speed. Definately a better match for your current engine combination.

Thanks Ron, is this the site your talking about?  http://www.compu-flow.com/TurboAction.htm   Just trying to spend my money the right way, unlike some of the things I've done in the past. I still need to make up my mind on rocker arms, hoping I dont need rollers. Also my underdash wiring has some wires butt connected and I'm looking at the year one harness. There goes my budget for the year! Hoping I can maybe hear the car run this year. I'll feel like I'm making some progress!

Several vendors sell turbo action...the one you listed is fine. You also need a matching flexplate and larger 7/16in converter bolts. 440 source has the flexplate and Summit will have the converter bolts.

Unless your cam is a solid flat tappet or roller you won't need roller rocker arms....the stock HD rockers from Mancini are fine. I just installed the year one harness....it's a work of art. 


What cam are you running ?

I have to look it up but off the top of my head its 495 lift 268 duration I believe.Any better vendors for that covertor that you know, I do need the flex plate and bolts as well.I hope year one has a good discount out..I think it was like 500.00 for the underdash harness but its better than a fireball.

Hydraulic cam ? If so, just use the HD stamped rockers and some good pushrods....no need for adjustable rockers, inmo.

That link you posted above has excellent pricing on the T/A converter....Mancini lists the same converter for $80 more.

Its a 383 .30 over 10:1 compression. Do you have any different links for a 383? Thanks for the help Ron!

[bmoparmofo]
