225 slant rebuild for more power

I run high volume oil pumps on my slant , and already reused it on two camshafts on the same motor in my dart no problems 50 psi cold 45 warm. Although I would not run comp cams slant six camshafts, I have a slant im building that broke off the oil pump gear straight off the camshaft.
I’m looking for an intake right now I’m thinking Aussie speed long runner 2 barrel and Holley 350 avenger. I think this will be a good combo for the regrinded cam new lifters and 318 springs. Going to deck the block shave the heads and new rings and bearing hopefully I can use the same pistons they haven’t got back to me yet. I haven’t even thought about carbs and linkage yet but I know jack about carbs so please hit me with some knowledge thanks guys hope you all had good holidays.
