[QUOTE=. I have though about the T200,but the 460lE has such a low 1st gear 3:08 I believe.I am hopeing to keep the rotating mass down and I want to stay with the 10 bolt and a 4:56 is the biggest I can get into that housing.(Before I go to a 12 Bolt) QUOTE]

I am not an expert but I would think with a six cylinder you will need way more gear than that.

I agree. Better just get a 12 bolt at least.

That is also what I figure both the 200 and a 12 bolt. I have pretty much figured the 4:56 was not low enough.My 1st question is trying to figure what my trap rpm might be.Min. # in O/SA will be 3215 and the factory rpm is 6000. I've done some of the HP math and it looks like I need about 285HP to run .7 under. O/SA index is 13.15( I also weigh 260#) so it seams a diet is in the future.So right now I am getting the chassis undecarriage done ,and the engine comp. cleaned and painted.Thanks for any input.
