Re: Transmission question (700R4 vs TH350)

30% Anything Looks Good On Paper... Or Does It? I Had A Powerglide In My 68 Chevy.. Switched To A 700r4. The Over Drive Made A Huge Difference. I Was Getting About 11 Mpg Now About 16 Mpg. I Would Also Like To Add That Depending On Rearend Ratio, You May Be Looking At An Overkill. In My Case, I Drive Interstate And Highway A Lot. I'm No Longer Paranoid About High Speeds Because My Engine Stays Cooler With The 700r4 At High Speeds Which Also Means It Is Better For My Engine. Lower Rpms. The Powerglide And 350 Should Be Comparable Because Of The 1 To 1. Just Remember That You Might Not Save Tones On Gas... Well We Never Know About Gas Prices.. But What Benifits Will Be Gained On Lower Rpms?
P.s. I Put In A Lokar Shifter And Only Putt'n Out About 340 Hp.. Love The Gears.
