new best et/mph!! should I go 4.10s though?

[Josh91]

I've done the 3.73 to 4.10 swap. It was one of my best mods to date. Just for a quick comparo, I raced a buddy before and after the swap. At the time I had stock heads/cam, but did have intake, rr, pulleys, converter, etc. With 3.73 I would pull him out of the hole, but he would catch and pass me before the 1/8 mile mark easily. After the 4.10, I would pull him hard out of the hole and he would never catch me. That is quite the improvement IMO. Well worth the $$.
