Chevy Trans Adapters

Post by Powerflite »

I know that PAW and HotHeads both make chevy automatic trans adapters for the early hemi. Any experience out there with either of these or others I don't know about? I am looking at putting an overdrive trans on mine and getting a Chrysler A518 to handle over 500 hp or torque looks to put me back $2400. Ouch. Whereas, I can get a similarly equipped 700R4 for around $1200.

Also, is it better to spend the effort and money to put in a later model computer controlled overdrive for better shifting and economy?

Thanks in advance.

I used the PAW unit on mine with a B&M turbo 400 trans. Bolted right in with no problem. Not a 4spd trans but will handle 500 hp with no problem. You might want to check with TR Waters or Wilcap about other options.

GM Electronic auto trans on 392

Post by doctor_ratz »

I have driven a rod with a 4L80E GM trans and a TCI control module ---FANTASTIC. The thing will shift like a clutch type trans when under full throttle, and behave like your grandpa's Oldsmobile when you are cruising around town. It was behind a blown 572 chevy, so I think it can handle the Hp.
My advice - get a 4L80E for your 392, I did.
