RE: [BaadAssGremlins] 5/16 feeding 400hp

Your line is way too small, you need volume to feed the motor. Be careful, you can lean it up too much and hurt the pistons….

Went back and reread- one other thing you are using an electric pump back at the tank ? If not do so as it will help keep the carb and manual pump supplied even with the small line. Good luck Rick

I am having issues with my 401. Under load my car does not like to rev past 4000 rpm. My timing is 34 or 33 degrees advanced at 2500 rpm,
I have tried both an Edelbrock 800 cfm and Holley 770 Avenger and no difference.. I have the Duraspark ignition.. I will be upgrading to TFI as we speak.. I have a brand new Edelbrock RPM fuel pump(which made no difference..

I was talking to guys at the local speed shop shop and they said 5/16 line is the problem. I have heard 5 /16 will support 500 hp.

anyway I know at most i might have 420 hp.

My specs

401 bore .040
forged 10:5 to 1 pistons
edelbrock RPM heads/intake
Comp Cam 236-246 @ .050 520 int 538 ex
edelbrock shorty headers
Edelbrock RPM PUMP 5/16 in and 3/8 out

I looked at one of my plugs (i dont feel like taking headers off yet)
and it shows perfect light brown color...

Any suggestions?

Rob
