Anybody know the difference between Weiand SBC 4-71 intakes #7135 and #CV471? I got one of each, and the castings appear to be the same except for the logos and numbers... just curious if they are older/newer versions of the same casting, or if there's an actual difference I'm not seeing. Thanks in advance...
Judging by the change in the Weiand logo, I would say they are two different vintages of the same product. I believe that the one on the left is newer. Where on Earth did you find these? I have never seen a SBC 4-71 in person, loose. I have seen only a few on actual cars. I'd love to get one, but can't mortgage the house to get it.
Maybe one is from before 1998 when the Weiand Power & Racing company was sold to Holley Performance and the other is from after. (That's really just a wild guess, mind you.)
Yes Crager did make one too I saw one not too long ago sell for 400 which is a steal I have the 7135 version on mine its the newer of the 2 shown I would guess the CV 471 casting would be mid 60's vintage and yes they will bring really good money im guessing they quit making them in the 70's but thats just a guess
Good stuff - thanks. I should clarify that neither is for sale - I got uses for them both. I just wanted to understand the difference between the two. I'm really surprised there's not more info online for these things ...!?!
I have a partial Cragar SBC 4-71 setup I might be into selling. I got it to help complete a 392 hemi Cragar setup, but I won't really likely ever have a need for the SBC intake as at the rate I am going it will be about 2089 before I ever get my hemi project done enough to worry about yet another project. PM me if seriously interested. I am not super hot to sell it, but it is just sitting in storage doing nothing too important as is. I have the case, end plates and snout too, but probably want to hang onto those as I can probably use them for the hemi. The snouts might be a different length though. I haven't compared enough to check that. Also, I think Steve Sellers might be working on repopping some version of the Cragar 4-71 setups. I know he has one he has been working with but not sure what his final intent is with it. Check with him and see. As I mentioned to him, he should do a repop, but badge them as Seller's originals, not Cragar repops. personally, I would be more into a new Seller's version than a repopped Cragar. But, obviously the vintage Cragar ones have history factor. Check with him and see what he is up to.
Blake, I have a '62 Weiand catalogue I will look up when I get home, hopefully that will at least pinpoint to the early sixties which is which. However just knowing a little bit on early Weiand stuff I would guess that the C prefix is the earlier intake and I know the 7 Prefix was used later on, but hey I could be wrong. Reason I say this is that the Drag stars I have are prefixed like 'WC8' which is a Weiand Chrysler hemi 8x2 the blower intake I have is a WC671- easy to work out. so I take is that since they were making Chrysler products for V8's before Chevs the C mostly ended up as Chrysler, as in the WC, I do have a 2 3x2 chevy intakes that are C356. No W or V. will try to scan the catalogue when I get home.
If he repops them I hope he does and external back fire valve. You have to remove the blower to reset the back fire valve if it pops. The cone shape doesn't reseat itself very well. It happened to me at the track on a cold day and Ray at a local shop added a tee bar on the outside of the valve while we had the blower off. I have been able to use a pry bar to rotate it slightly with that tee and reseat the cone since that was added. Other than that they are great little intakes.
Here's my Cragar...you can see the extra material where they could be drilled for the 3-71 pattern...
I know its an old thread but does anyone know what the backfire valve should be adjusted to on 7135 Wieand manifold? Ive contacted their tech dept and am waiting for confirmation. My current setting is at 2" from the inside of the manifold to the outside of the spring cap. Any info I can find online states 1 3/8" which would wind my spring right in till the coils are virtually touching. Thanks in advance for any advice.
