Hp gain with Vortec heads enough to go IMCA MOD?
Ok guys need a little help . thinking about going from USRA Bmod to IMCA Amod and have any engine question. current motor 350 4 bolt , 40 over, 0 deck,stock crank, pm rods with arp bolts, KB flat tops, balanced, prc 108 cam, 882 heads , performer intake, and keith dorton 4412, 50/50 race fuel. this is a standard bmod motor and pulls good to about 7k which is what i chipped it at. any est on this hp? now because of local track changes i am thinking about going to Imca Amod with these changes: standard vortec heads with maching for new springs and 550 lift springs, performer rpm intake and a 650 or 750 carb. Still would limit rpm to 7k. what hp would this new combo make? and would the performer rpm be the right intake or should i victor jr? My thinking is that the 604 crate runs in Imca Amod and with Vortec heads I should be able to compete. Thoughts?
