My 1980 has been running a Holley 600 or 650cfm from factory. It has been rebuilt by previous owners more than 3 times. Now requires a rebuild or replacement. A friend suggests a new 750 Edelbrock. Any recommendation from other MC owners?

You don't want to put a 750 cfm carb on that 351. It would run very rich and you'd just be wasting gas and money. Likewise, you don't want to put an automotive carburetor on it either. The marine version has the bent J tubes on the overflow part of the carb so if it does overflow gas it just goes back into the engine rather then all over the motor.

Skidim sells a replacement marine carb.

Even a 650 Eledbrock will be half the price and is Marine compliant. My marine mechanic has good results, just looking for the right solution.

I went with an Edelbrock 750 Marine last season on my 240SC with an HO454. Never ran better!!! Was an easy instal too. You would want the 600cfm Edelbrock marine carb.

Good luck,

Matt

If cost is more important then safety then it's on you to make that choice.

Safety is obviously first, but I don't have data that says either one is not safe. If you have any, I would appreciate the heads up. I would install it with all required fittings and hoses. The Edelbrock is a marine carb.

I am not familiar with edelbrock marine carbs. I assumed you were just using an automotive carb.

Anyone use a carb spacer / wedge that makes the carb level, rather than tilted with the engine? They make 5 and 12 degree wedges.

Use the 1" spacer plate with no particular angle. That has worked for me for many years of 4160 use.
