Welcome to FEBO.
I have 15X8 with 4.5 inch backspace P275/60R15 tires on the back.
15X7 with (I think 4 inch backspace) and 215/65R15 tires.
A lot of guys run 225 or 235/60R15 tires on the front. I like the 215/65R15 tires better. They are around the same width and a little taller.

I used a 1/2 inch pickup tube and it caused more problems than it is worth. I got it to work but I would not do it again. My engine is a 440 block 512 stroker.
If I had a suggestion, get the Hemi pan and 3/8 pickup tube from 440 Source.
I am assuming you are using a 440 block also...

OK, this is out of a Chilton's repair and tune up guide for Barracuda Challenger 1965-72. It has a copyright date of 1972. I have the 16th printing dated January 1988. This book seems to show 11 inch rear drums for 383-4 engines and larger and 10 inch rear drums for 383-2...
OK, all you brake geniues...
These are pictures of one of the rear drums on my BS23N1B 1971 'Cuda. What size are they?
The fronts are factory disc brakes.

I use my phone to read this forum all the time. Heck I probably use my phone on this site more than my computer. The only time I really need my computer is to upload pictures. My phone can't do that here. If you ever wondered why I leave a couple of marks at the end of every post, it is...
I am using six pack 2300 series Holley float carbs. Thanks for the complaint on the car. I will be putting on white billboards soon. I will post more pictures when I am done.
