Why is that? How can this be? 70 Road Runner 528 HEMI 4sp FY1 70 Road Runner 440+6 V-Code AG 4spd EV2 69 R/T 4 Spd Dana 3:54 AG Vert B5 69 R/T 4 Spd Dana 3:54 AG X9 V1X V8R-WORKING 69 R/T Auto/Console 8.75 SG Vert R/T B3 08 Challenger 1st Edition Hemi Orange 69 Super Bee 4 Spd 8.75 SG AG F8

It'll make the intake only fit that eng but since the heads are on with that particular thickness of head gaskets you have no choice live every 24 hour block of time like it's your last day on earth

The Paper gaskets that are sometimes included with the valley pan are to thick to use in combination. The old sets that had the thin oilskin type paper gaskets were great for use when installing an aluminimum intake.. I am truckless..
