800 Holleys to start out with, because that is what we have. Will see how they do on the dyno and go from there. Being prepped now by Ken Jones performance. He is somewhat of a legend around the Midwest, but mostly in his own mind. I will most likely end up with fuel injection on mine if it turns out that I like this boat.
The 8-71 has a chiller, I would put one on the 420, but where would I find one?

I`m running a baker mechanical pump with a regulator and tank return. -10AN lines
mild is running the Holley pumps self regulated and no return and it seems like no issues.
I was running out of fuel pressure with those at 6000rpm. Fuel gauge would start to drop to 4psi till I`d let off.

Where did you have your regulators set? Just wondering if you had set to the max flow, I'm running mechanical pumps on sc build with dual carbs and have the regulators but wasn't going to bother even installing given the new build. Mainly just to eliminate plumbing.
