“Best” all around axle ratio: ~450hp w/ A904?

I had a very similar combo that on 245 street tires and with a 4-speed/3.55s went 106 in the quarter@3650 pounds. The Wallace Calculator points to 330 hp, so you might be bang-ON!, except ..... yes, I was shifting at 7000, lol.
This was a one-run deal with street tuning. It was a 2.5hr ride to the track each way so when it went 12.9 I did not care to know any more.

Definitely north of 320. I'd bet anything is makes north of 360.

Thanks Gent’s. IF I ever get to dyno this engine (not happening) I’d hope for better than 360 hp. But IDK.
I took it to the track @ Orlando w/mderoy to dial in the car some. With 3.55’s on 26” tires and a tight converter I wasn’t expecting much. The best trap was 101 with a OE shifter that gave up the ghost after the first run. First run it fell on its face since the carb was a OOTB Summit 750. (AKA Holley 4010) Mike gave the carb pump shot a quick twist and said try that! It worked but the shifter would not go into first. I also never let the tire pressure down from the street driven 35psi. It was terribly slow but still fun. Just stab and run from idle.

I know there’s lots left in it but I have not been able to get into the track yet. Just do remember it’s a street driven car designed for easy driving and not racing the track.
