With that cam , you're goiung to find it tough to run pump gas (depending of course on what flat tops they are as far as pin height) You could also do without the 2600 stall converter. You really ought to go with a bigger cam to take advantage of the compression, 2600 stall and gearing.71, 302 30 over, flat top forged pistons with valve reliefs, wind age tray, 65 289 53cc heads screw in studs ported, polished, with 195 in 160 exh valves, beehive springs, 1.6 roller rockers, Wiend stealth intake, Lunati Voodoo cam Duration 262/268, Lift .499/.522., 600 cfm vacuum sec Holley, 3/4 length ceramic coated headers, sfi dampener, March under drive pulley's, MSD pro billet Dist 9mm ford racing wires, blaster 3 coil MSD 6al box, Northern alum rad Spal electric fan.

I am not sure what it is going to make I will lose some due to my AOD but I do have a 2600 stall and 380 gears in the 9. I just wanted a fun driver I am 99% sure I will have to run some octane boost with the iron heads. May switch to some AFR 165's later. Should be breaking in soon just been to busy to get to it the last few weeks. have to finish up some wiring and such. Here is a pic just for the heck of it. the felx fan has since been removed. and all the wires and such added.
My guess would be 275 to 320 HP depends on the heads. (How good the flow really is)
I did a search on TRW pistons and found a site that sells em and had a list with the comp ratios vs chambers. They would be 11 to 1 with 53 cc heads. The 60 cc ratio was 10.2. That will change too with different head gaskets and if the heads have been milled.Thanks...then I should be even more pump gas friendly. I though I had read and or calculated it at 10.7 to 10.9 depending on the gasket cc.
