While I hate to disagree, I do love to argue but the Holey ST is not that bad. Actually for an under 6500 rpm 351W it is an excellent intake. A friend ran one for years and finally bought a Victor Jr expecting big gains. Barely gained a tenth. He also ran it on a stroker with good results.
I used the FE version on my 428 with a 2 inch spacer. When I switched to a Blue Thunder I also saw very little gain from the swap.
Port matching is a given ( FE needs welding to match a CJ port) and for going racing an open spacer helps a lot.
