    The 650 DP is plenty.

    I concur. You cant beat it. If you need a street carb, the Quick Fuel HR-680 would be a nice deal as well, but for best performance the 650DP.

    Full roller don't tell us much. No way we can tell you what carb size you need with out knowing ...
    What cam size, what heads, what compression,

    Considering its a 355CI most likely not high compression and under 500HP and most likely not going to RPM over 6000RPM...its not difficult to select a carb. Most people over carb as it is. There is a simple math to it and being around engines of all calibers helps.

    It is possible he has 18ยบ heads, locomotive springs, .750" lift etc etc where a 1050 would be his best choice. But most folks with that kind of motor already know which size carb to use.

    I would say 650 to 750. If it was me I would go quick fuel 750

    Sorry guys left out some details. 2.02 heads, 10.5 pistons, cam 280h, lift 480 duration 230 @ 50 lift ......sorry guys when it comes to motors i know little. i bought this from my father who had it built a yr ago for another that has never been ran. Talked to a good friend of mine today and he was saying really no need for a 750 on a SBC.
