I'm a T-56 hater, plain and simple. Too long, too big around, too heavy, not enough benefit from another gear to spend that much money.

You would not be able to tell any difference in performance between a 3.73 and a 4.10 gear. My $.02 would be to run the TKO 600 you have, put a 3.73 in the rear, and cruise at 70 in the lower 2000's.
If you stick a 3.73 in it and go the route of the 325-50-15 tire that pretty much is equivalent to running the current 315-35-17 with the 3.31 so I would expect no change in gearing performance. Would you still advise using an aluminum flywheel in this instance or would you be moving to billet steel style.

I have a 408 that Vizard built, dynoed 600+ hp. When I got it I replaced the sup vic intake with vic jr, the 950hp carb with a 750. It has more cam then what you are going to use. It is a monster.

I also have the ally flywheel, no problems, have the same looking clutch, no problem, also have a single disc organic/metallic, no problem. The springs on the disc help to smooth things out, the other car doesn't have these and I can tell the difference.

My rear gear is 3.55 or so with the .82 od, no problems. I really like the gear spacing of the tko600 and .82 od. Any change in the rear gear to a larger number is going to be useless, skip shifting? You go through the gears so quick.

I also have a vacuum advance on the dizzy, this helps a lot on the sound out the exhaust, burns cleaner also.

Me and another guy were out the other day, halfway into the throttle is about all the concrete available.

Sounds like you have a nice setup. I've driven a 445w that makes a tad over 600HP and TQ using hydraulic roller, victor Jr., 850 carb, single disc clutch billet steel flywheel, 3:46 gears with a .82 Tko600 and avons. It is completely streetable and full throttle could be used.
My car will need more gear than the 3.31...I'm going to a much taller rear tire that when used with a 3.91 will match the older SPF gearing that was 3.73. I'm willing to try it with the existing 3.31 but I don't believe it will be enough gear for me.

I'm not sure what tires Vector1 is running but I will be going from Goodyear Eagle F1 GS-D3 to drag radials.

If those are the same tires as mine they aren't worth the rubber they are made of when it comes to traction. I'm running the 315/35/17s and with my 3.31 gear and down on power 427 it spins them unless I am in 3rd gear. I would think a stout 302ci could kill these tires.

I figured an update was due. While the motor was out we went ahead and committed to having it completely freshened up. All the machine work and head freshening was performed by Craft Racing whom originally built the motor in 2004. There is still alot of work to be performed but we are getting there. We are in no hurry to get this completed we are taking our time and want to do it correctly without cutting any corners due to budget ect. I expect we will be back on the road early spring. Big thanks to Pman1961 as in no way would this be happening without him. I also need to thank Lance from Craft Performance and Brent from Lykins Motorsports for their advice, assistance, and parts support.

Engine back together - 427W all back to original spec with the exception of a cam selected by Brent Lykins

T56 Mocked up so the mounting brackets could be fabricated

Engine back in the car temporarily. We will need to remove the engine, headers and sidepipes once again before the final install

Thanks for the shout out ACE!! We will be back at it this weekend verifying driveshaft length and see how the shift lever in its current state fits in the tunnel hole. I expect a little mods there as well. What the pics do not show is the cross member has been modified and welded in place. Once tranny is out, we'll prep and paint frame, etc. I'm looking forward to the completed project as these are the improvements I plan on doing myself one day!!
