well, gettin down to the nitty gritty, i finally found out the antics of my engine, first, to correct myself, it is a 350 4 bolt main with arp bolts, have a 10/10 forged crank wi01 and with chafered oil galleys for better splash and powder metal piston rods with 3.48 stroke, my pistons are dished pistons with molly rings and a cam with 280 lift on intake and exhaust with advertised duration of 480 from lunati voodoo cams, the heads, which was my main subject is one 601 and one 801, looked and looked and found the cast and year and the 601 has a 54cc chamber and 801 has the 53cc chamber,  i have 1.5 roller rockers with screw in studs, i have stud pins since my lift is close to 500 with solid flat tappet lifters, have teflon valve seals and new springs that are good to 550 lift with a 1.160 coil bind, larger valves were put in, i now know the size of them, my intake is1.94 and the exhaust is 1.50, here is the big wuestion, how would i find out what size intake and carb i need and how do calculate what size stall converter i need without using a dyno, will this application of parts be suitable for u all, tell me what u think, willl it blow up in my face or will it last a few thousand miles for, at least a few ppasses i hope,
