I'm in the process of building a turbo windsor and my target is about 700hp street driven. Can you guys give me some pro's and con's of each for a steet car. Now this is not a daily driver, only a "night time" weekend vehicle so no AOD opinions please. I'd appreciate any feedback. Thanks.
How tall a tire? What rear gear? You want to do mostly "rolling" or standing starts? Manual shift? Transbrake? Can't really list pros and cons without more info...
Not sure on tire height, but 3:55 or 3:73 gears, trans brake, and manual. Will mostly do roll racing since it will be a while before I can get the suspension for dig racing.
OK just my opinion, I have a lot of 1st hand experience with C4's and none with Powerglides. That said:
Pros for the C4:
3 speeds
2.42 first (better with your 3.55's) vs. 1.76 in PG
cheap, plentiful performance parts, easy to rebuild
Lighter
Made by Ford
The guys I know running powerglides whether in GM or Ford vehicles are making really big power (so are you if you have 700hp) and run that trans in racecars where they know EXACTLY what RPM they want when they hit the traps. All things being equal, 1 shift takes less time than 2 shifts, too.
I think generally it makes more sense in a performance manually shifted auto trans streetcar to have a 3 speed.
