I am looking to add some reliable power to my 500hp 502,.i am currently running.88 heads An a 525 cam hydrolic roller,.i have an opportunity to buy a procharger kit an a 177 blower,.i only am looking to add about 75-90hp around 4lb boost,.please help

pass on both and get a 8.71,you and your engine will be happier!

I can't really afford that,..these are my options

What procharger unit? The 177 is good to the upper 500's from what I recall off top of head. Above that she will make heat

There is zero comparison between the m1 procharger and a 177 or even a 250/256 for that matter. The m1 is much more efficient.

502, with 250 blower, 525EFI cam, and Dart 310 Pro 1 heads. Non intercooled.

I would not put a 177 blower on a 502.

I have 8 years with 177s on 454s reliable 100 hp addition. Sounds killer verses procharger. Both setups have 5 lbs of boost. Blower also less garbage to install. Fuel cool and water to air chiller makes for too much .

I'll just put this right here.

There`s another option: leave it alone till you can afford to do it right.
