Can you use a later model intake from say a 1976 with EGR and AIR injection on a 1968 engine? I know you can block off the EGR but do the AIR injection holes cause any alignment issues?
Dont know for sure but I'd say it would not work. Probably could be made to work but why go to the trouble when theres correct intakes available.
Not mine. A buddy picked it up at a swap meet. Probably the only Buick thing there besides model cars and hub caps.
It would certainly bolt on, bolt pattern is the same for all BBB heads. The A.I.R. rails are pressurized by the air pump, and blow air into the small holes in cylinder heads meant for A.I.R. Those holes lead to the exhaust ports. No holes in the heads, no where for the air to go, not that it matters with no air pump. I'd say you can use it. EGR just gets blocked off with a plate. They are fugly intakes, but use it if no other option.
pretty sure you can block off the air ports. I know you can the heads on later engines to use any intake.
I put it in the small block group because it is for a 68 350 2-bbl engine that a friend wants to convert to 4-bbl. He found this at the KYANNA (KY & IN) swap meet in Louisville. Another buddy and I were counting Buick specific items. We found 8 hub caps, 2 model cars and a few brochures. Nothing engine related. My other buddy must have bought this before we got there.
One thing you do not want to do is to use a Carb that was made for a EGR Intake with no EGR hooked up or on a Intake with no EGR without recalibrating the Carb richer. Without doing such you will have a surging ping monster to deal with!
He only has the intake. He's more than likely going to run an Edelbrock that he already has on it. Not sure about any tuning or anything about the Edelbrock. I was just trying to insure the intake would work if the ports were plugged.
Indeed. My first Buick 350 was the engine that intake was used on. My 16 year old dumb self didn't put the oil galley plugs in behind the timing gear, so I broke it in and drove it about 10 miles with probably as much oil pressure as a lawnmower. Fixed the issue and it only lasted 5500 miles before it ate the rear two rod bearings. Cam was fine though lol.
