Has anybody ran a 500 performer on a stock port here? I'm curious to hear what you guys are running for jets, rods, and springs. I found a lot of articles using 500cfm and larger on street ported motors and 13b 6 port but nothing for a stock motor.
Thanks!

I'm pretty sure I need to invest in a holley red fuel pump or equivalent. My airtex I have in there now only flows 35 GPH 4-7 psi. I ran a length of fuel line out the hood from the FPR and reattached the pressure gauge to the end so I could see it while I drive, under WOT it drops from 5.5psi down to ~3psi gradually up to 5k rpms. Anything after 5k it starts to go lean and sputter.
Meh.... more money lol

I do realize that a 500 is slightly larger than what most would recommend on a stock port, but I do have plans to street port in the near future. I'm just trying to get this thing to run decent for now until I get another motor to port.
