That would be a *****in car and would haul a lot of ***, if thats the response you wanted. Stock pistons/compression or is that changing too? Most big cams want higher compression, stall, and rear gears. I see you stated the stall and gears but nothing about the bottom end internals.

It will probably be slower than you think.

You need to research exactly which parts and their specs before you can get any answers. Just throwing performance pieces on an otherwise stock engine can actually make you slower if the parts are not matched to each other.

I've seen it happen too many times.

I agree, do you have the part numbers and or specs for the parts you are looking at? Those would help in making a determination of power. Also, have you already bought these parts?

I don`t know if you mean a car or truck 350, but most truck 350`s of those years had small 1.71 intake valves, they`re not much good past 3500 rpm, even with a larger cam. As already mentioned, compression means alot, as of the factory ratio was likely 8:1, but most importantly, flow is power, and that`s what makes the heads the most important piece of any buildup, the cam plays a role, as does the intake, carb, exhaust, etc. If it does have 1.71 small valve heads, you can use a RV cam like a edelbrock performer plus, small tube headers, performer intake, and a Q-jet carb and it`ll fry the tires off without braking it from a dead stop and will pull like a dump truck until about 4000 rpm, then it`ll fall flat on it`s face. High torque engines are a ton of fun on the street and get decent mileage too, I`ve seen many go thus route as a buck saver mild build, and every time, it didn`t disappoint in the fun department, not to mention there dead set reliable.

isn't 750cfm a bit big for a mild 350?
if I;m right heres a fromula I found...

displacement X peak RPM / 3456 = carb size.

most warm 350's do well with 650 vac. sec for the street.

I have a 670 avenger on a SBC that makes around 425HP and for the street it works great - feels like fuel injection.
