bowtie headed engine.what kind of hp to be expected?

[jk93]

looking at getting a bowtie headed 350.has aluminum weiand intake,je pistons,manley i beam rods,gm crank.balanced rotating assembly.bored 30 over,running 4412 carb.has crane cam gold roller rockers.not sure of cam specs at this time.does anyone have an estimate on the horsepower it may be putting out?also what would be a safe rpm to turn this engine?as always thanks for the help.

If you can get 450hp out of a 4412 engine you will be doing good.You won't need to turn it over 7200-7400 because of the carburetor.

will these internals withstand 7200?

The crank is the weak spot.

Which Bowtie head ??

[jk93]

they are phase 2 heads.what crank would you fellas recommend?im on a limited budget.the track i race is 1/2 mile fast.my car has to weigh 3100 with an open motor.thanks for the replies.keep them coming please.

the carb is actually 500cfm.not 350.what other rules do you need to know?im not looking to build a motor ,i was wondering if this would be a decent hp motor and what rpm it could handle.i would change the crank if necessary.thanks for the replies.
