Wanted to know if you have any info if the hi ram will fit under the hood . I have the flat plates on mine with stock stands . I could not fine any info here or else where . I know you have your mounts on this truck . It looks like it has good clearance if it is the hi ram .

The manifold on the project truck was the Hi-ram, you shouldn't have any problems fitting it with your mounts either.

Toddoky , Just wanted to give a update on the hi ram intake . I have got my engine apart and decided to try to check clearence for the intake . I see the the intake is 12.3" tall at the highest point from the valley on the front . I stacked 2x4 on top of the valley cover to get 12" at the front . The hood would not close . Apparently the flat plates and stock stands and mounts must hold the engine up . I took one 2x4 off which made 11" tall and the hood would close with 1/4 to 3/8 clearance best I could tell . Just wanted to let you know for future reference .

I really wanted to run the high ram . The low rise is not a option for my engine upgrades and power level . The holley system was not out at the time I did my swap or I would have used it .

I look forward to getting my exhaust . I ordered the 3" system behind the rear wheels last month .

That's unfortunate that the Hi-Ram wouldn't work for you; all the non-Hooker fitment info I give out is relative to using the Hooker mounting components as a reference point and making my best guess from there.

Yea , I understand that point .

I re looked at the schematic dimensions and noticed it said at the bottom , engine block lifter valley flange . Was this measurement taken from the block or was it from the top of the valley cover . This may be a make or break deal . If it was from the block I will re measure . Just trying to make it work .

The engine block surface.

I'm not sure what the chances are but does P/N 12646HKR fit 67-72 frames?

I love the clearance this thing offers for true duals on a dropped truck.

I wish I knew myself if it fit the early trucks or not, but installation in those applications has never been attempted.
