Do any of you guys know the max port width dimensions that a Victor 351 (Jr, super etc) can be ported to? A friend and I were discussing a 420" W with 4V cleveland heads.
The heads in question will have a filled floor so the width is the question. From a quick glance the 351W and C have about the same port centerlines. Bolt holes will have to be re-drilled I think.

Please correct me if I am missunderstanding you , but are your contemplating installing a 351W Victor Jr. on a 351C head? If so, it's not going to work.  ------------------

Other than the bolt pattern being wrong, why not? The port will ne filled so the 2" or so height of the "W" intake will be close. The width is my concern. What am I missing?

By the time you hog all the aluminum to match the ports, they'll be no manifold left.------------------

After thinking about it, Alex is probably right.
The 2V port and the "W" port are in approximately the same place and similiar shape. The 4V port has a higher roof than the 2V port. So when I fill the floor of a 4V head, the mismatch is about 3/8" or more. Damn. Someone should make a 4V clevor intake. I would hate to weld a rear end seal plate on my SVO intake (9.2 deck A3 port shape) to mate it to a 351W block (along with spacers).

what about using a 351C intake with thin spacers? Or an SVO 9.5 deck height intake with welding and filling to match the lower ports?

I found a Yates intake at a swap meet and modified it for my 9.5 deck/4V cleveland combo. You'll have to fill the Cleveland head's port floor, slot the bolt holes in the intake, and drill and tap ports up front for the water crossover(there's usually blanked holes already in the intake), then port the livin' hell out of the intake to match!------------------

Didn't Nascar used to use this Clevor combination?? There should be some good intakes for this combination out there somewhere if you look in the right places..

Didn't somebody buy up all of the Track and Street Boss tooling? I swear that they produced a Cleavor 4V intake. 
Also, wouldn't the FoMoCO M-9424-X351 intake somewhat suit your needs? ------------------

Bush Performance re-introduced the track Boss intakes. They are for the 2V heads. Not near enough meat to grind out for 4V. SVO did make a intake for the C302 heads on a 9.5 windsor block. They are Mucho expensive now. Edelbrock still makes the AH-II intake which is for C302B heads on 9.2 deck windsor based blocks. The C302 will work with a lot of grinding and a little epoxy.
X351? as in cross breed, or cross pollenate?

The number on my intake is M9424 _351. There should be a character right before the 351, but it is not stamped on my intake. I bought it at a swap meet for $80.00, I think it was a defect as the none of the bolt holes for the cylinder heads was drilled. It also had a ton of aluminum in the top of each port. about 1-1/2" to be exact! I think it was originally a restrictor plate intake. Bob Holmstrom out of Michigan used to sell yates intakes converted for 4V clevors. I don't know if he still does this or not. ------------------

I know that Kuntz & Co. has a Wilson modified intake that will work but I also know that he wants a ton for it as it IS very valuable. 870-246-2595 ask for Jim if you are interested. ------------------
