Need opinions, going to setup the boat this year with an offy tunnel ram on my BBF. I have two sets of carbs, both Holley mechanical secondaries. One set is 750's the other set is 660 center squirt and opinions on which is better or worse ?

I run 660s on my tr on a 455 and there bitchin. Everyone bitches about how they suck gas but there honestly not bad. Its not a prius by any means but whatever. There made for tunnel rams id run those

I know on my setup its a veryyyy tight fit. So tight we had to grind off the holley logo on the middle bowls.

Damn.... That's some tight clearances.

I run #6109 750 dp in line and my clearances are good, and they have secondary metering blocks with side hung bowls..... The difference is the 750s are prob dps and are progressive throttle linkage from primary to secondary barrels while 660s are 1:1 meaning all 4 (8 in a dual setup) open at the same time.... Really it prob doesn't matter cuz if ur running dual carbs on a tunnel ram, the last of ur concerns is mpg
