the LD4B is a very good intake as well as the LD340 intake

I am running a LD4B on my teen and was a big improvment over the performer

the holley street dominator is another good intake for a mostly stock street 318 also

its a low rise,single plane intake that works with a spredbore carb and a square bore

I tried both and they worked great,but went back to the LD4B for better gas milage

a stock intake with a q-jet is fair to midland performance and is also over looked a lot

ditch the performer and the sp2p,IMO

the LD gets my vote hands down
