Fuel question

I am putting p&p heads, cc306, roller rockers, p&p intake, 58mm throttle body on a 383 lower end. Will I need larger injectors and possibly a inline fuel pump?

Agreed. No way the stock injectors are going to be able to keep up with that, or the stock pump for that matter.

Look at the Racetronix plug-n-play kit with the Walbro pump, can't go wrong there.

Re: Fuel question

Theoretically the 30lb injectors are good to about 384 fwhp at 0.5 bsfc and 80% ds. Your setup is surely producing more than that. Go with at least 36lb, can get 460 hp at same conditions.
