Inliners International Forums General Discussion Hi Performance Carb cfm with B&M 144 blower

I would say a 600-650 would be a good choice.
Years ago a girl named Marry had a nice (IIRC) 65 Nova w/a 355 SBC & a Weiand 144 blower & the blower chart (B&M) for that size engine & blower a 750 was supposed to be the biggest she should use, she tried it, it ran good, then she wanted to see if a 850 would work better, she ran a 1/2 second faster in the 1/4.

So even those charts that B&M had are just good reference charts, there are many variables that can change what is needed.

You can use a smaller carb if you like, just will not get as much power & boost.
