    Friend had a 355 with double humps 2.02/1.60 milled!! with around the same compression with a little better than stock bottom end but he had a proform 750 and a little bit bigger cam (solid roller herbert) and high rise intake he made around 500 hp to the flywheel.

    Not even that much. JMO

    I say not much over 300

    P.S. Take that big carb off of it.It would run better with a 650 cfm

    Sorry I upset you.

    Just stating my opinion that 875 cfm is way more than a 355 ci engine needs. Especially one with double hump heads. The engine would be crisper and more fun to drive with a smaller carb. Unless you are spinning that thing 9000 rpm an 875cfm is too big.

    It's your engine ....If you like it, I love it.

    ???

    Tod,
    You are 100% CORRECT!
    My 1st thought was 350-375 But I was BEING Nice!
    IF you think Is SCREAMING,then take it the Track and It will tell you DIFFERENT?
    Put a 4776 Holley on It and it will Probably p/Up 3-5 Tenths!
