Re: What Fuel Pump for 350?
I know it's not a performance part, but I've had success with AC/Delco pumps like this: http://www.summitracing.com/parts/ado-40725/overview/ and this: http://www.summitracing.com/parts/ado-40987/overview/
I also had a really nice AC/Delco pump with 1/4" NPT ports that was "clockable" meaning you could rotate it for the best fit. Wish I could find that P/N. Edit: Found it: http://www.summitracing.com/parts/nal-6415325
According to Summit Racing, fuel pressure required for a naturally aspirated 400hp engine = 400 x 0.5 / 6 = 33.3, so this pump's 30 GPH rating would right on the edge at full throttle for any length of time.
The less expensive pumps in the links above have a 5/16" input nipple with inverted flare output. But, hey one of those worked great on a 5,800 RPM 383, but probably wouldn't support that RPM for very long.
Just found this one, and I gotta wonder how much different it could be form the ACs: http://www.summitracing.com/parts/crt-m6624
