RE: Elderbrock Perfomer EFI intake
A 347 is typically done with a bore and a stroke.
346.952 with 4.030" (bore) x 3.40" (stroke) or 347.466 with 4.125" (bore) x 3.25" (stroke).
Intake bolts up just like on a 302. The block dimensions do not change.

i think u made a good decision as in getting the rpm 2 i have it on my 306 and with the cam it pulls mad hard above 3000 and have not gave my new motor to the floor yet let off at around 5700 and it was a good sotp feel

RE: Elderbrock Perfomer EFI intake
Keep in mind as well that the rpm range listed on those intakes is the range in which the intake runs best on a certain displacement. In the case of RPM intakes for a 302, 1,500-6,500rpm is the best range the intake breathes in on a 302. It will run under and over that range, often quite well, but it's going to be dictated by the particular engine. RPM intakes have been known to make peak power as high as 7,500rpm in some applications, and run down at 1,200rpm in some.
