With my small cam and old ***** it feels great
Interesting... I was wondering if a 3k may be too much with the 3.23/2.48 first gear.. so I'm looking at keeping 3.23s and going with a " modified" stock 80e converter.( upgraded clutch and restalled to about 2-2500) or 3.73 gears and a 3k circle d 258mm? Just curious which would be quicker on the track... ?
