Agree .Ask How I know this?

I agree, you'll be glad for any and all extra ground clearance you can get

Here’s an excellent online racing calculator which helps decision making. For tire diameter answer, you input proposed rear gear ratio, anticipated engine rpm and mph at stripe. This calculator is user friendly and lightning fast with answers.

I had a 1970s dragster with an 8-3/4 Mopar (489) rear with Mark Williams axles and spool and had no issues with it. It would work fine for your project.
jeff/21:
we ran 10x30 on 10" rims with sbc flat top pistons, flat tappet cam, vortec heads 1 carb on gas hooked up really well.
free isn't always the best 8 3/4"are a fair rear end but are harder to get parts for and will take away from the resale value/ are you going to run drum or disc brakes we went cheap disc from a small ford truck
chev impala calipers with circle track mounting brackets heavy but they worked well after the first season things changed weight removal bigger motor bigger tires more upgrades in the trans alky injection more work but a faster car
plan around your budget and add 30% little things add-up

Getting back to the three inch ground clearance - dragsters and altereds are allowed to have body overhang of 30" ahead of the front axle.
Not in line with your vision of period correct? OK, but if you do it right that front nosepiece - or wing - or bumper - or whatever can be made to deflect downward so as to trip the finish line lights two feet ahead of the front tire, effectively making your lane 1318 feet, allowing your car to trip the clocks two feet before it arrives there.
