The guy that's selling this lives near me. I don't know where he keeps finding this stuff.

I bought a pair of 351C heads from him once and I couldn't believe the stuff in his garage.

Yes. A guy had a bunch of them at the big Columbus Ohio all-Ford swap
several years back. They were in the SVO catalog one year and had an
SVO p.n (-T351) but I don't think they were ever made legal for racing
class they were desined for. The SVO catalog is at home but as I recall
everything about them is custom and there was a long list of custom parts
(rockershaft, valves, pushrods, pistons, etc.) that's required to use
them. Don't qoute me but I thik there may have even been a special
part number for a tunnel port block (different location of the lifters
and pushrods to match the heads).

Things like this make me believe class racing rules have stunted the
development of pushrod engines. If you design something that works
too well it gets outlawed and never sees the light of day.

I just checked out the ebay link... what's the purpose of 'split' intake ports? Is it to promote swirl? They're far different from the old FE tunnelports, with pushrods running through ports big enough to stick your left leg into

The intake with that port layout almost looks like a chevy intake

I just wonder how well it really worked. I mean, even chevy went to spread intake ports like a Ford has for their NASCAR stuff.

I saw those heads at Columbus too (and in the motorsport catalog). The guy claimed the one set was off of a car ran by Dick Trickle in ASA or ARCA or something. I think the heads were an attempt to have the intake ports more even in length. Supposedly that was an advantage with a single 4 barrel intake. However, the fact that Chevy now has a ford intake layout I'm kinda confused about the whole thing!

This was actually a good balance between the Ford and chevy port layout and does require "special" individual parts. Because of chevys protests, they were not allowed.

RDI north of Charlotte used to have several sets of heads and intakes for sale. Probably still do.
They require special Jessel rockers also.
Dick Trickle won a Daytona or Talledega Arca race driving a car for Junior Johnson with a set of those heads. That the only time I have ever heard of them being used.
Supposidly developed my Johnson's team....

I think you need to keep in mind that all these specialty pieces are cast with unfinished ports with plenty of room for custom porting. Can you imagine a Nascar engine builder using heads as cast?

Now that I'm married, the team vanished.

This set up was used in ARCA by my friend Jack Bowsher. It was the fastest car on the track until it suffered valve trouble due to the extra heat incurred by the design.
