the holley street dominator is a killer intake for a SB 318

single plane,low rise.small port intake just for a teen,be surprized how well it works on one being a open plenum

the edelbrock LD4B is another killer intake for a teen

duel plane,high rise,small ports and is a big boost to performance

I run that one with a 600cfm and voodoo roller cam,headers in a 85 stepside

big bump over a stock 4-v

a stock 360 intake will work with good results but does have the large ports...done it many times on a 318

i run a lot of 318 with the 360 heads also with a stock 4-v intake and q-jet carbs

IMHO..best bang for the buck..LD4B hands down

then the holley street dominator

both very good intakes
