i just read a post on here about people talking about 3.73s to 3.55s and i have 3.27s right now and was going to put in 3.73. I already have the gears and all and have the HCI plus the novi 2000 nothing installed but should i stick with 3.27s or is it worth to put in 3.73, and how much would it cost and what would building up the rear end intail. Please i need help here i dont have much experiecne with rear ends and gear ratios. Thanks

I would install all your motor stuff and supercharger and find out what rpm you hit in the 1/4 over the trap. Depending on what rpm you go over at the 3.27's may be perfect.

You'll be fine with 3.73s. I'm running 430 RWHP under boost and nitrous with 3.73s. No problems with the gears at all. They feel great.

You wont run out of gear either way, there are people with much bigger blowers and whatnot running 4.10s, sometimes even lower(numerically higher) gear ratios and they are just fine. Depends on if you want a daily driven street car or a weekend warrior.

Youll be fine with 3.73's. Are you gonna run the stock block? HCI and a Novi 2k... If you are on the stock block watch the boost, your gonna be makin a lot of power.
