Looking for some advice on whether I should use 3.73s, 3.90s or 4.10s. I'm going to be building a Heads/Cam LT1. It has an A4 with 3000 RPM converter. This isn't a daily driver but it may end up with nitrous on it.

Anyone else have similar setups?

TIA,
Kyle

You will probably hate yourself with 4.10's in an auto...but then again its not a dd. I would say go with the 3.90

I managed 1.614 60ft. yesterday with a heads/cam Caprice with 3.73s 3400 stall and 27" tires, am I interested in trying 4.10s, yes BUT at the same time I drive it too much to leave a gear like that in all season. With your lesser weight I think deeper than 3.73s will hurt drivability more than it gains you on the strip.
