Are you planning to run both fuel pumps at the same time, or is the 2nd a backup? A 340 is the max flow the FITech regulator can handle.

You have to run drag tires. Drag radials or slicks are OK. Just no regular street radials. Every tire will sit differently on the rim, but the tread should measure the same, no?

I brought:
Oil/filter
cap/rotor
plugs
coil
MSD
alternator
air filter

I drew the line at major component failure, but a guy had his car burn down essentially and put in serious work to get it running again...so it all depends on how determined you are.
