you need big heads, cam,carb and some real compression to utilize a single plane intake.
can your short block spin the high revs to utilize a single plane?

i run a hurricane (vic sr knock off) and like it alot. was like $140

check out professional products, they are cheap, but need alot of cleaning up on the runners for port matching to bigger heads, its made in china so what can u expect,lol.

i'm a bigger fan of the air gap manifolds myself..... although fitment under a factory hood just wouldnt happen in that case.
