If so how much estimated horspower/ torque? Started out as a 502 mag.
509c.i., 088 rec port heads w/ 2.25int, 1.88 ex valves, bowl ported. Crane roller rockers and hardware. Crane 731 rollercam. MPI intake setup.lightning headers.
Dyno#'s would be good but a guesstimate will work too.

I would guess around 500-520....probably pick up a little from being a 509 and give a little using MPI system. Put intake and carb on and might see 550ish. Cam is too small to benefit from twisting the motor above 5500....

Maybe just a little more with the ported heads and added cubes...

I would very much agree with these numbers. I have a lightly ported MPI intake, Dart Pro1 heads, a slightly larger camshaft, and 9.5:1 compression. Mine made 540HP on Lingenfelter's dyno between 5200 and 5300 RPM.

I'm running similar engines in my top gun except I'm using ported dart heads, a slightly larger cam, 9:1 compression, modified mpi intake manifold and redesigned fuel system.
I'm running about 540+ HP at 5400 RPM's.

This is my engine combo using the azsm type mpi lower intake and an M3 s/c procharger. I was just wanting a ballpark figure for bench racing purposes. I appreciate the responses.

BGIII- my manifolds have shortened runners that were also extrude honed by ASM. I scraped the entire cool fuel system. Now I have 1/2" pickups with #8 lines from my tanks to RAMCO fuel/water filters, then #8 to WELDON 600 pumps, thru check valves and #6 to WELDON filters and then to the front of the fuel rails and out the back to WELDON regulators with mechanical psi gauges then #6 returns thru fuel coolers and back to the tanks. I probably could have omitted the fuel coolers since I went back to the tank but they can't hurt. It was an expensive fuel system(x2) but good insurance and maybe a few MPH.
Hope that info helps
