325-350 HP 360....is a stock mechanical fuel pump adequate?

[FlamesAreWicked]

I bought a Carter “muscle car” pump from summit for my 340.. it’s probably making a tick over 400hp.. we’ll see how it does.. I actually bought it before the 340 engine became an option. I was just gonna replace the one on the 318 at the time of purchase..

No stock mechanical fuel pump generates 25 PSI. No 350 HP carbureted engine needs 25 PSI either.
Come on, man....

You mean you're not trying to run 9's with that little 360?

No matter what is said about flow and pressure, too much is just about right. Put a pressure gauge on the car right in front of carb or fuel injection rail. And record it if you can?
If at ANY point in a run with a carb, the pressure drops below 25PIS in front of the pressure regulator (and that regulator better be in front of the carb somewhere) you ARE RUNNING out of fuel. I've proved this way too many times on different cars. On a 65 Dodge Cornet big block running low 9s, we found this out the hard way. After the fix, 35 PSI up to the regulator (down to 25 PSI midway 1/4 mile run) then regulated to 7 PSI big Holly Dominator,
picked up 3 MPH and 2.2 ET. 5/8 ID line to regulator (it was a triple bypass system) then -10 fuel lines to carb. (Think needle and seats opening and closing at least 20 tines in 9 seconds) Recording this proves this info.

With all due respect, what part of your response has anything to do with the question in the original post?
