For your carb the BG400 or the Magnaflow equivalent will be just fine. I have used a BG400 for years. Its still on the car now even though it is way overkill to feed my surge tank in the front. As stated above though you want to run good size line. What you need to remember is that it takes roughly twice as much methanol as gas for the engine to run. So you need twice the fuel supply. Typical good setup for rear mounted cell -12an from tank to pump, -10 from pump to regulator, 2 -6 or -8's coming out of the regulator to the carb. You have to run over 20lbs of pressure from the rear to the front or you may have stumbles launching. Ask me how I know
