I bought a holley double pumper at a swap meet a few years back. The guy said it was a 650, he showed me some numbers on the carb. but i forgot where they are.

Is there ANY way to tell what size it acctually is, i bought it outta a crate and im planing on gettin a Proform center section for it, but i just wanna know if it is a 650.

Thanks

it says List-6210-3 (and under it it says) 0417.

also if it is a 650 could i buy a proform 750 center and use that with the parts ive alrady got.....im really lookin to get atleast 750cfm without having to buy a new carb.

thanks

the 6210 I believe is a 650 spread bore most lilely used on hipo chevys such as 327 to the 402 from '65 to '70. The square bore of the 750 won't match up. I've only known holley to make only two spread bores....650 and 850
