The Buick Motorsport Intake Casting 25500029. Is it a off center of a on center. I think the Edlebrock intake was on center and the Buick Motorsport was off center. Just need to confirm.
My recollection is that all the Buick Motorsports 4BBL intakes had the same casting #. This excludes the goofy one with the carb twisted 45 degrees. The only way to be sure what you have is to mock it up. From what I've seen the Buick Motorsport intakes with the short carb flange were Off Center and the tall carb flange were On center. I wouldn't say this is set in stone though.
Put the heads on the block and set the intake on top. See how the ports and bolt holes line up. If it's the wrong one for your combo it will be pretty apparent.
Only solution is to cut the intake in 1/2 and re weld it but it could be ugly. I have an spare offcenter intake but one side is milled .100 not sure howd you fix that one either.
Stage II heads are everywhere. Why do you want new ones? All that is going to do is cost you a bunch more money to have them ported etc. I know one guy with 9 sets. Shoot me a PM or whatever they call it these days and I'll put you in contact with him.
norbs, there are few shops around that will make you a set of headers and fit them on your car, THE FAB SHOP,
here in indiana, they have a web site, i know a couple more, just get your pocket book out, its only money,
good luck oc,,,
Thats me, my username was changed. Its very unlikely I'll be making any more headers in the near future. I'm cutting back on side jobs and concentrating on my car to get it ready for next year.
I have two oncenter and one offcenter, one oncenter has been converted ,
the offcenter is on the engine in my car now, my onffcenter was on a N/A engine when i bought the complete engine. it had a big holley domniator carb.on it other wise it has had a lot welding on it
it looks good and has .050 smaller ports than some stage heads,
i tried to sell the oncenter intake it was on a ruggles engine that i picked up,
anyway i still have it for sale, good luck oc,,
I have an off-center with 2550029 on it for sale. Has been converted to injection, gasket matched, and a flanged welded on to use a hemco upper plenum.
Comes with a coil pack mount custom made for this intake. The intake has been powder coated and looks very nice. The intake in the link and almost identical to my except that the injector bungs on mine are higher on the intake as opposed to being more towards the head. http://gnttype.org/techarea/pictureguides/intakes/customstgII.html
