Injector Size
I have a 502 that is being bored and stroked to a 540. Also having a bigger cam put in, not sure just what size yet, but a little bit larger than stock along with heads being ported and polished. Just wondering what size injectors that I will need to run with 5psi of boost with a procharger? Also what deg of timing should i run or will the computer take care of it? LASt of all will I need to have the computer reflashed?

Marren hooked me up on what I needed AND had the best prices. I'm going to guess #55 but get an educated opinion from a real builder. (that's what I have in my high compression 540's)

Assuming worst case conditions of 60degF air temp (conservative, since post-blower air will likely be much hotter), 29"HG barometric pressure, 11:1 AFR, and 133% voleff (5psi boost ~ baro + 1/3), you'll need ~60lbs/hr of fuel. If intake air temp is raised to 150, it'll buy you ~2 lbs/hr of head room. 1 AFR increase (leaner) will buy you ~5lbs/hr of head room.
