Can any1 give their opinion on what kinda horsepower/torque my new engine should be making and also what timing is a good place to start (total not initial) and what kind of et I can expect providing it hooks up? The engine is a 383 with 10-10.5 compression forged speed pro pistons eagle steel crank stock style forged rods I have the trick flow 23* 195s with 64cc chambers 2.02/1.60 valves and heavy duty dual valve springs lunati cam is 246/256 duration at .50 lift is .550-.571 but I have 1.6 roller rockers and its a solid flat so IDE have to do the math but their lashed @ .24 intake .28 exhaust hot and I know the lift is about .588-.596 @ .50 (like I said IDE have to do the math for exact that's just a ruff estimate) it's rated from 3500-7500 rpm power band. The intake is a Vic jr speed demon 750 vacuume secondary carb msd 6al box and msd hei cap and rotor. The trans is a built th-350 with a 10" 3000 stall (will be getting 4000 stall when money allows) and has a 3.73 posi ( stock until 8.8 goes in then will be 4.10 gear) I have 26" Mickey et drags and comp enge 3 ways set at 50/50 and eibach drag springs. Any and all opinions will be very helpful thanks guys.
