Call a cam company. Ask to speak to their tech dept., tell em what you've got, what you want to do, and what rules apply such as your vacuum rule. They'll recommend a cam that you'll be happy with.
The tech. rep. sits at a desk, computer program in hand, might even have information on the tracks you plan to run. i've never been sorry going this route. Myself, I always call the cam company that rhymes with train.

i'd worry about those heads before a cam your not going to get much with those small valves and that little carb what you gain in compression isn't worth the lack of flow find some 350 heads with 1.94/1.5's and you'll be much happier. right now pretty much any cam isn't going to work as good as it could with that setup

calling a cam company isnt allways the answer Iv tryed that about 3 times all junk.
the cam we like is a lunati bracket cam thats about what you want its a 460 lift like 224 duration not sure on the part # but if you want it I can get it for you summit has them for about 130$ with lifters. That cam has 3 track champs and well under way for the forth and thats with 4 different drivers. builds torque #s that are outrages dyno proven. And we had to run restricter plates that choked our 500 carbs down to what your 350 will flow.

Are you racing at St Tammany Speedway?

Badd_C0, what is the rmp range that you need to pull the 18lbs? I was running an street stock engine close to yours, except w/58cc small valve 305 heads and cast steel 4brl intake. The cam I used was Comp cam XE268H which had a very good power band. I ran the bleed style lifters for achieving the vacuum at idle. The engine made major power using a 600cfm holley 4-brl, would turn 6800 in a 3300lb car on a .3mile high bank track using .688 gears. You might want to consider that cam or the XE262H. That one is rated per the comp cam spec sheets to pull 18.5 at 1000rpm and use the bleed style lifters for insurance. Good luck.

not sure what the vacum is on the lunati but i will find out we didnt have a rule for that but it does idle smooth worst case the rhodes bleed down lifters would help I race up in central MN i sold that motor all i have is one with a custom grind so i will check with a friend of mine that is still running it
