Shelby 289 and 302 Cross-Ram intakes
« on: October 11, 2019, 08:42:30 am »
Boys,
Especially Randy, what are your opinions on the Shelby 289 (and 302W) 4V and 8V Cross-Ram intake that was marketed by Shelby. I used to own the 8V version, however never ran it. Thoughts?
Current lifelong project:
1969 Mustang Fastback/FOX chassis, 6 speed, 4 wheel discs, with a modern Can-Am 494 (Boss 429), Kaase headed, intake mounted with a 1425 cfm 'B' Autolite Inline carb, ala Trans-Am style…Whew!

   Scott,
  Gary Goeringer ( TA22) ran one on the Bill Maier car when he owned it with great success. He was a bit tight lipped about the power advantage but he kept running it which means it was good!  It is a good "base piece" that could benefit from some internal changes and still look "stock" on the outside. I tried to use one with the Paxton blower I used to use but the box interfered in too many places to be practical. FAR superior to any other cross ram for the 289-302.

Do you think it's better than the Magnesium cross ram for 58 Weber's that I used to have?

Roy,
Im sure Randy will agree with me, your talking about two different animals. Your Weber 'cross-flow' is an IR intake, not the same as a traditional large plenum 'Cross-Ram'. Im sure your intake probably works better tho…IF you can find the 58's.

Roy,
Did you have the 58 MM Weber's? That seems to be the downside to the 58 Weber manifolds is that nobody has the carburetors.

   John side drafts are easier to find than downdrafts like I had.
 
     Roy,Yes I would say with certainty that the box manifold was superior. Torque for sure and at 'least" equal in power. Webers were always losers to me.

I never did get the Weber's for the intake. I looked for a couple years and then someone told me that if I did find them they would be about $10,000 and I believe today closer to 20,000. I traded the intake to Jim Inglese for a set of brand new Weber's for my Mirage GT40 engine which Jay Cushman now has.

Roy,
Absolutely correct, 58mm Webers are almost impossible to find. IF you may remember, a guy named Bernard in So-Cal during the 1980s had a genuine red 427 SC Cobra with the rare 58mm Webers on his car. He later returned (with the car) back to his home in Germany.

The only ones I've ever seen were on a couple of Can-Am cars and vintage racing.

I thought that SOHC motor addict Scotty had three of them in the 1980s when I was dealing with him for FE wedge motor parts. He had a SOHC 58MM intake, that he showed me along with a couple of the carburetors.

John,
Yes, Scotty had a ton of rare 'Cammer stuff. His '32 was also featured in a Budweiser commercial around the late 1980's. Shelby Rob knew him very well….Im sure he will know what intake you are referring to.

   The ones you guys are talking about are DOWN DRAFTS. Side drafts are not quite as rare as the "39" downdrafts. The three I had came from Bruce Sizemore's Modified Production  Pinto. He got them from Ford Engineer Denny Wu and WERE serial 2,4,and5  of the run. Down drafts will NOT work on a side draft manifold.

Randy,
You are absolutely correct. Bernard and Scotty's intakes were down drafts. Randy, btw, Im sure you will remember Bernard and his Cobra…he bought that intake (and other parts) from R.M.

Jay,
'Shelby' Rob has a couple. That said, I don't think he's selling…I already asked him last week!  lol
