So I gather this is the current pro-flo efi manifold (pinched from Jtsllc1's thread) that has been modified to the 4150 flange.



Other than changing the flange, there is probably not a lot more to be done. An improved air-gapped Torker would tick a lot of boxes. 4150 flange is just a lot more universal for all sorts of applications other than Edelbrock trying to flog their full Pro-Flow system. Kill off the Torker in the process since there are already plenty of them floating around for people who really want to use them.

Be mindful of finished height so people can keep things under the bonnet as this would suit most people.

Couple other thoughts:
- better PCV baffling than RPM AirGap
- try for similar low-end and mid-range but better top-end than AirGap.
- fit under a flat hood without carb spacer and with drop-base air cleaner ... but spacer helps for those with cowl hoods or similar needing more plenum volume.    

The AMC RPM AirGap has good bottom end and mid-range, but drops off quickly on the top end compared to equivalent intakes for other makes.   Would sacrifice some bottom end to gain on top.  

Thanks, RD

Here is the same manifold but we made a thinner flange and coated the intake for heat sink. After testing with the lower plenum height we found the plenum size was more then adequate to feed the engine. This was the non ported intake we ran at the EMC. The second picture shows the extra water on the drivers side but we had to block all external water per the rules for the EMC.

Here is the air/oil separator we ran at the EMC because the E vac system and the Vacuum pump was not permitted. The second pic is the final height  ported 4150 EFI based on equalizing the runners.

I like the way you think...
Buzzman72...void where prohibited, your mileage may vary, objects in mirror may be closer than they appear, and alcohol may intensify any side effects.

I doubt they will, but for a gen1 just
mill .03 off each head face
and drill two holes.

That's it.

Sounds like your talking about 67 to 69 Gen2.

GEN1 has different configuration with water ports and top cover below the intake.
71 Javelin SST body
390 69 crank, 70 block & heads
NASCAR SB2 rods & pistons
78 Jeep TH400 w/ 2.76 Low
50/50 Ford-AMC Suspension
79 F150 rear & 8.8 axles
Ford Racing 3.25 gears & 9" /w Detroit locker
