I did a quick search but didnt see anything about this. My buddy has a 1954 chevy 235 and a late model (72?) powerglide. I know someone on here has done this or atleast could point us in the right direction. Trying to find an adapter plate and info on what flywheel he'll need. Thanks
Bendtsen's sells em. $795 for the kit (adapter plate and flexplate). http://www.transmissionadapters.com/Chev%20235%20six%20cylinder%20to%20Chev%20V8%20Style.htm http://www.transmissionadapters.com/Pricing.htm
Why go to all that expense, just to have two gears? That's even a step down from the original three speed. And a costly step down to boot. Go with a T-5. Best all around swap for the backside of a 235 ever. If an auto is the dead-set decision, the at least go with a 200r4. 235's need more gears, not less. r
Raven, Im in the market for a 53-54 chevy. Most Ive seen for sale dont have powerglides. I need an AT in mine (bad knee). You mentioned a 200r4 as an option. Im not tanny smart at all. What years could I find a 200r4 on and which models came with them stock? Also, would any 200r4 bolt up to a 54-62 235 or would there be an adapter plate needed? Thanks alot for any help.
An adapter will be needed for any later GM automatic, but it will be the same adapter in most cases, giving a lot of flexibility about tranny choices. A Powerglide will work fine for normal driving chores, a TH350 3 spd auto would be better, perhaps best, since it is stone simple to install, widely available and durable. Only a passing gear 'kick down' cable to hook up, unlike the 2004R, on which the Throttle Valve cable is CRITICAL as to adjustment. And while I personally like the 2004R, if you arent doing a lot of highway driving it is really unnecessary. For a TH350, a rear end ratio from the high 2's to low 3's would work well. If you do choose a 2004R, you'll want a rear gear of at least 3.55 and 3.70 would be even better. Ray
