sbp wheel suggestions for 64 Valiant

Back in ~1974, I had a 65 Valiant SW with a 340 in it, and Hooker fenderwell headers were the only choice. It barely turned corners with the factory 13s on it.
Today there are better choices.
IIRC Hooker makes an under chassis for SBMs that has five pipes going down in the usual way, and just 3 in total going thru the aprons. Those would be my Choice.
5204 is a number that I seem to recall.
Get your exhaust sorted BEFORE you start working on your project as the Hookers may not work on all heads, all transmissions or all steering boxes.
After you get that sorted, find an oilpan that fits your chassis.
I would leave the body work for last, cuz there may be sheetmetal mods required to fit the wheels and tires.
