Overdrive Options

I've thought about it a lot actually, even if you weren't as gifted as myself to have a shop, You still have to fabricate a cross-member either way. The cost to cut out and weld in a 1/4 piece of steel for the torsion bar support is laughable. We're splitting hairs here. For me it costs $700 to put in a 42RH with a decent torque converter. I lost count what Mopar to ya spent on his 200r4. As far as putting more power to the ground with 200R4 vs 42RH I still don't see conclusive evidence of parasitic loss between the two. Still going 42RH. Not going to debate further until I see something concrete.

Prior to switching to the 727, I could have given you a front row seat to parasitic power loss due to the MOPAR transmission. Now I guess you will get to see for yourself. Like I said... If all you are wanting is the final gear ratio to be close to 3.0 or something like that... Things are cool. If you want good acceleration, I am certain my car would have been much stronger with a 3.0 ish rear end ratio and a 904 or 727 than it was with 3.91 gears and the .69 overdrive transmission.... Much faster. On another note.... I did like the lock up converter!!! Mine was right at $1000 for 2800 stall speed. Todd

PS. Just putting a 1/4 piece of steel in place of the torsion bar support is not strong enough. There are huge amounts of load on that support!!! As I did the calculations on the strength that the factory support, I was surprised to find out how strong it was, and what it would take to achieve the same amount of support from replacement parts. Flat steel just won't do it. FWIW.
