I am set to dyno my truck this sat at rpm offroads open house in Bristol. I have never had a truck or a car dyno tested before but thought why not see what it makes. Here is my combo let me know your guess and I will post results Saturday evening. 466" stock crank with eagle h beam stock length rods. Probe. Forged small dished pistons 10.8-1 compression. Dove-c heads ported with 2.19 1.8 undercut valves. Flat tappet solid cam .648 in .624 ex lift 246 256 duration at 0.050 best I recall it was spec for a member here for a similar combo by Scotty j. Roller scorpion rockers 1.73 ratio. Ford racing victor intake no port work and 850 demon carb with 1"wood spacer. 1.75 tri y headers into 2.5 ex with cut outs. Still running full accessors minus ac compressor. Elec fan. But I will be turning a one ton 10.25 rear axle and t18 four speed with 205 t case and 33" mud tires so it's a lot of rolling mass. I turned this to 7,000rpm last truck pull but I'm sure I'm losing power by that rpm. I'm guessing 385hp and 495tq think I'm close?
