5.o hp knowledge needed
Is there anyone that could help me with figuring out about how much horsepower my motor is putting out and what else without going crazy would help gain more? I have an 87 5.0 block that’s been bored .030 over, balanced pistons, rods, crank, flywheel, and harmonic balancer. Honed rods for wrist pin fit. speed-pro forged pistons w/metric ring lands, Dura shield coated main and rod bearings, eagle connecting rods, oem factory H.O. cam, roller lifters, gt40 heads, pertronix y pipe headers, ford cobra duel plain intake, Holley 4 barrel 600 cfm carburetor, and a k&n air filter.

I forgot to add I have an h pipe and 2 1/4 inch exhaust, the ignition is Pertronix billet distributer with 9 mm plug wires.
I also noticed by reading a little more I posted this in the wrong area. Sorry I was not sure wich area it should go. If I could figure out how to move it I would. Again Sorry.

So what would make improvements in horsepower without doing major work. I was thinking of adding roller rockers to it this winter but not sure if there are major differences in each brand. They should give another 20 or so right.

No, not at all. You increase horsepower by increasing the volume of air & fuel that the engine takes in. Everything you've done so far is purely cosmetic/strength oriented. If you want real horsepower, you need a good top end. Heads/cam/intake.

Ok. I thought the gt40 heads, other than being heavy were good heads. What would you suggest doing from here. I would like a good driver but would love more horsepower as well.
This is on a 65 convertable that was cloned after the 66 gt350. That's why the cobra intake, was trying to keep it a classic looking not really a restomod.
