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.
