looks nice how much hp will a fully ported intake gain over a non-ported on indy 360-1s?
Not really much to be found in "porting" a 4150 flange ICH intake, as long as the port match & runners are right, the big power gains are found when converting it to a Dominator plenum VS running a Dominator on a 2" adapter on the 4150 plenum. Really all depends on the combination... but normally I see gains in the 15-25 HP range eliminating the adapter & converting the intake properly.

Holy crap that thing is short now With that low cut plenum it looks like one of those 4500 M1's now I can see it already... I have you go through all that work only to find out that the carb & air cleaner won't fit in the end anyways Ryan, did you remember to modify it to accommodate the bypass hose?

Height wise, yeah it better damn well be about same as your M1 LOL But no spacer required on this...
Forgot about the bypass hose, you're the only person I know who still runs one... looks like I'll be breaking out the 3/4" NPT tap tomorrow. LOL

Raff, I had sent my 4150 W5 M1 to Ryan to have it converted to 4500 but he said there just isn't enough metal in the plenum to do it.(because of the plunge cut on the outside of the plenum) I'm sure he'll clarify if I'm off base.
Thanks... I'll look a little closer tomorrow but if it wouldnt make any HP or TQ I wont waste my time and just put the adapter back on

Those M1 LG runner 4150's are notched down for accelerator pump clearance... That missing material is right where the 4500 carb needs to sit & seal. You'd have to weld up those accelerator pump slots & re machine the flange to convert one to a Dominator. & if anything I think it would make that manifold worse after studying them.
Thanks Ryan.... you just saved me a pile of work... I'll put the adapter back on and open that up and blend it in
