Doug, the 10.5s only fit with a rear spring relocator kit and judicious slicing of the inner fender well and the outer inner wheel lip. The outer lip is not rolled, just relieved along with the wheel house trim. On the inside the snubbers and perch were excised back to the inner well. The rims are 15 x 10s with a 5.5” backspace. The Strange housing is 1.5” narrower than stock.

351crules, the trap rpm is 7K and the shifts are at 6800-6900 Peak power is at 6600. Without powershifting the Rs drop bit but have to check logger to see by how much. Engine is tired, not likely 630+ hp at this point. That value came from a fresh build on a numbers friendly dyno.
The rear set up is Caltrac bars with their split mono leafs. Also their 9 way adjustable shocks.

745 peak hp. No idea at what rpm, ( not enough cam specs which is fine cuz then I can’t get it wrong)

That would be awesome Joe. That would double or maybe triple the number of FE powered machines there at one time, lol.

Dale, the slicks are a 29 x 10.5 Hoosier. D06 compound. Run them anywhere from 13.5 - 12.5 psi. Car is is 3650 with driver and 1/2 tank. I recall you sharing the relationship,( or lack thereof), between mph and ET in the past when I lamented that the car is not quick enough for its mph. Most of that is the driver here.  So I’m looking for help from the equipment, lol. Figured a decent 60’ would at least find me a tenth off the ET.

This trip was the first time out with my Viking DAs in the front. Wheelies are tiny now, front end more under control. The old 90/10s had the car pogoing one through third. I had the rebound setting on 4, then 2. Might try 0, the 90/10s were very good on extension but the compression was laughable on my car.

Thanks much for weighing in.

Fortunately there was a rescheduled test n tune Friday. So many rain outs here in the Northeast this summer/fall. Was going to go two other times this month but Ma Nature said forget it.

Managed a new low ET even with a poor 60’. Went 10.68, mph of 125.71. 60’ was only a 1.56. Car has 60’ 1.46. Problem was my line lock was wonky. Only one good burnout all day, car would just slide. The good burnout netted a 1.52 on a different pass.  So I feel car has a 10.5 in it but won’t find out this year.

I have some arms. The needle bearing assemblies are frozen from being in a humid environment. I have them soaking, could be freed up possibly

That steady speed A/F is fine Howie. If you are under light load cruising it could be a little leaner too.  You’ll get to tune more after that mess gets cleaned up. Some of those upstream adjusters look mangled. Is that just the camera?
You have some spare Erson parts?
