615 hp requires about 52 gph, with correct A/F ratio. A Carter 460X elec pump will do the job nicely with adequate reserve; 100 gph, two models inbuilt [ dead-head ] reg or bypass reg model.
Are you sure you want to use aluminum tubing (what grade)? Aluminium is softer than steel alloy tubing, subject to fatigue failure due to vibration and impact damage. A-N fittings are great but so is compression fittings (Swag Loc, or Parker Hanifin or equal). Don't think Aluminum tubing would be SAE and Government allowable???? for safety regulations?? Just thinking out loud....

I am I the process of replacing a car-length of braided line (rubber inside) that leaks like a sieve, with a 1/2 aluminum line, with A/ N fittings, to duplicate the setup (1/2 aluminum, a/n) that has lasted for thirty years on my other car. Also replacing a leaking holley blue, with a trick flow 140, again like on my other car.
The pump isn't quiet, or loud, just average, but I can't hear it when the engine is running.
You know I grew up in the 60's and 70's and I have been around muscle cars since about 1970 and I just got used to wanting to hear that electric pump run when the car was running. So a little noise from an electric pump makes me smile because I know its working. Ron
You are faster than me, (for now, lol) but maybe my exhaust is louder than yours. Flowmaster 3.5" big block mufflers, tailpipes to the bumper. When the engine is off I can tell how its pumping by the sound. I had a Paxton 150 that pumped great, but lost prime when it sat for a couple weeks, even though it was lower and behind the tank. We'll see if the Trick Flow is better. The Mallory 250 gerotor was quieter than either the TF or Paxton.You know I grew up in the 60's and 70's and I have been around muscle cars since about 1970 and I just got used to wanting to hear that electric pump run when the car was running.
