What can anybody teach me about these manifolds? I've seen a few on Ebay and it looks like they were made in 1x4,2x4,3x2 form look pretty basic with a flat pad on top that looks like any of them could be opened up on a bridgeport to except a blower. If fact i seen to recall seeing one made for a blower. I haven't been able to learn much about them doing research online except that they were made by two brothers from Oklahoma and they may have teamed up with Ed Donavan on the Creitz & Donavan T/F F.E.D.team.
they ran a fuel dragster at MoKan in the early 60's I believe their drivers name was Coleman ---he never lifted--saw him running in the gr*** past half track many times--I think you are right about the Donovan connection---guess I don't have the info on the manifolds just sparked some memories
This was Jim and Bob Creitz,,Tulsa,Okla... Jim was not as involved as Bob...unfortunatly Bob has just p***ed away this year...
Have not seen one in years but as they were mfg. pretty early I would suspect they have very small ports and are meant for 265 early 283 motors.
He also had 2 different design intakes, the late ones are all 2x4s, and ive never seen a late design 1x4 or 3x2, but yes the 1x4 2x4 and 3x2 all shared the same casting and they just machined in what ever carb pattern they wanted. i also have seen a creitz blower intake and it too also looked like the same casting with the exception of the blower mounting tabs. ill see if i can find a pic of the blower intake, i think it was one ebay. heres a pic of my 3x2 creitz and a pic of a late creitz 2x4 and pics of a 1x4 intake, 2x4 intake and rims and gas pedal all from the hamb he also made spindle mount rims jeff
Got to talk with Bob Creitz a few years ago at the Hot Rod Reunion in Bowling Green. He told me they built several different manifolds mainly during 1958 -59 . Sadly he has since p***ed.
