Help selecting T-56 Magnum Gears

[kaptainkw]

Howdy Gents:

I'm in the market for a T-56 Magnum but would like a little input on selecting gear ratios. Here's the car:

• '67 Camaro Convertible (Dynacorn shell) converted to a '68
• AME GT Sport subframe, solid mounts, DSE subframe connectors
• LS2 with L92's on the way ~450 hp at the crank
• LS7 Clutch and Flywheel
• C4 IRS Dana 44 w/3:45 gears narrowed 3"
• 245 40 18's all around but my go 275's in the rear (~26" wheel diameter)
• I think a stock 1st Gen convertible is ~3600#. With the above and less the cocktail shakers I'd say I'm 3200-3300# range.

So here's my goals for the car:

Almost stock look but with all the modern amenities (tilt w/DBW cruise, power windows, doors, top, etc.) Sebring conv. seats upholstered to look like deluxe houndstooth, etc.

Fuel economy is important but it is a muscle car after all!!! If I were to say its primary intended use I would say it is a touring car for crusing vs. racing. Frankly the C4 IRS is somewhat limiting on what I can put through it and it is a convertible after all!

I've been told that for 1st gear launch you want between 10-11 final drive ratio which means I need the 2.97 first gear (10.24). And I think I want the 0.50 6th gear. I've looked at the rpm charts, etc. and I think I have enough torque so as not to have a problem in 6th gear.

I'd like input from those who know these cars and given my goals.

Thanks in advance!
