Default FPR for carb setup

I saw in a prior thread that someone used a Mallory 4307m regulator.

Is this best product for the sawp?

Default Fpr

In the Summit book it is part #MMA 4307 Mallory. It is a 3 port with return line on bottom.adjust your FP to 4-6 lbs. I run mine at 5 lbs for everyday driving 1 to 2 lbs of fuel pressure in very noticeable in power & MPG.I have had the mallory FPR for about 4yrs. It's about half the size of an aeromotive works great. Tie your FPR & return line down tight with 50 lbs of FP going back to return line it will jump a bit.

Has springs for both carb and injection so should you ever wish to run a aftermarket injection setup , no need to buy new reg
