I'm going to pull out the 4-speed and put in a T-5 behind my Y-block so two questions: #1-I'm looking at two ratios for 1st gear 2:98 or 3:35/3:37's,which would be best for around town stoplite to stoplite driving? 2nd--Anybody gone to a hydraullic clutch and done away with the Z-bar(more room for header clearance) and does it work on a heavy car(Courier) when launching off line?
