YOU SAW IT HERE FIRST
The custom built 455 low profile intake manifold 
skunk works project– well– its here 
This baby has bosses for drilling injectors for a direct port kit and NO exhaust CROSSOVER 
! Betcha your intake is cracked on the thin wall between the secondary ports– go ahead I’ll wait till you check———– See, and when that crack reaches the floor of the intake the exhaust gases in the crossover will contaminate your vacuum and guess what, your motor no longer goes! every intake we see has this potential problem. This all new aluminum intake will allow you to keep your flat engine cover while updating your motor to an all new intake. $600 and cheap if you think about the hassles it will save you. Yes, they are in short supply, allcustom made stuff like this is so give us a call– if we have one it’s yours, if not you can get on the back order list and have one of the next batch.
I would like to thank Gary Rockwell for having the gumption and faith in the GMC community to put this intake project together and get it to market.
