Am considering purchasing a Ford Racing Performance Parts (formerly Ford Motorsport SVO) Engine block. Considering a 351 SVO Siamese bore wet sump block, 9.2 deck height. Wanting 427ci out of the engine. Have a set of Cleveland style aluminum (B302) heads and intake for this setup.

Here is my question for any of you who may have experience in this area ...

The SVO racing blocks all seem be be cast with Windsor oiling systems and cooling system with NO cast in provision for a waterneck on the front of the block like the 351 Clevelands have. My intake manifold (matched to the heads ... M9424-B351) is a Cleveland style with no waterneck.

I am sure others have overcome this problem. What sort of setup is needed to put this motor together to run?

Thanks
Gene

Someone correct me if I'm wrong but if your putting cleveland heads on a windsor block you have to have a clevor intake.

He made a water mainifold. He drilled and tapped the end of each head for a 3/4" pipe fitting. Has it plumbed where a ~6" section of pipe sticks out from each head toward the front of the car. The pipes are connected to a tubular tank. 2" diameter X 12" long. The tank has a large fitting for the upper radiator hose in the center. When he first made it it was copper/brass, he had one made in the same size of polished stainless steel. Looks very nice. I know of another car that runs at my track with the same setup.

Ohh.. David, these heads don't use a clevor intake. These use a Motorsport intake designed by Jack Roush. The heads are the precursor for the modern Yates heads in NASCAR. They have canted Cleveland size valves, a rectangular Windsor style intake port and and exhaust port that is much improved of a stock 351-C. They look similar to a BBC exhaust port. D shaped, the D laying rounded side up. The intakes are dry like a 351-C, and have no water neck. The intakes look like a Victor Jr, minus the water neck.

I suspected that I may have to fabricate a manifold like the one you described. The B302 heads do have screw in end caps and can be removed for such an instillation.

You are correct in your information and description of the heads and intake. I have the B351 Intake which is port matched to the heads. The B351 actually was a A351 milled to work on the Cleveland 9.2" deck height block.

Any chance you could get me the e-address of your friend with the setup ... or a picture of the car showing the modification? It would be appreciated.

I am currently building a Cleavor motor ... a 393 ci engine using Windsor block, Boss 302 heads and Motorsport A385 stroker crank. I will be using a TrackBoss intake on this motor.

However, I am thinking ahead to my next project and wanted to do the 427 using the aluminum B302 heads and Jack Roush intake. Just had to figure out how to use the 9.2" deck height SVO block and get it to work.

Thanks to you both for your quick answers.

A pic of the car is on my website, but it doesn't show the engine. It does show what the engine can do though.... It's the Maverick on page 3

Thanks, the pics have me drooling! Is that a 6.09 dial in on the Maverick???? Is the 1/8 mile track or 1/4 mile? Just wondering!

Yup, that's the standard approach. Ford Motorsport used to sell a kit for it.

>These use a Motorsport intake designed by Jack Roush.

Edelbrock also manufactured intakes for the high ports, both under their own name
and Ford Motorsport's.

Actually, the intake ports were Cleveland based as well. The earliest versions (A3's)
used an intake port that was essentially a 4V with the bottom third or so filled in.
Later versions were narrower versions of the A3. The exhausts were circular in unported
form. A3's and B351's usually remained circular. C302's and D302's were sold in an
unported form and often got the D-port.

There were wet and dry intakes available in both 9.2" and 9.5" deck height versions.
You can still buy the Edelbrock AH-II intake which has a cast-in waterneck like a
Windsor but the intake fits a 9.2" deck Cleveland or SVO block. Not sure why you'd
want to do that. I prefer dry intakes since it makes for quicker manifold changes.
More common are the dry intakes for 9.5" Windsor or SVO blocks.

The screw-in end caps on my high ports don't look like they will budge. The previous
owner chose to tap a smaller hole near them. You can also buy water neck kits meant
for Chevy's though it's really a generic application. Moroso (and others) may have
what you need.

>You are correct in your information and description of the heads and intake. I have the

Yup. Also the bolt holes are drilled in a different spot though they can be
elongated to fit either deck height.

One word about the Motorsport blocks, don't assume they are immune to core shift
or other quality control problems. A friend had to send back a new block when it
wouldn't pass sonic check. Also, some are sold in a semi-finished state and require
align honing, etc.

If you're considering an aluminum block Fontana makes them in addition to Ford
Motorsport. I believe it uses a Cleveland oil pan though the rest of the oiling
system is Windsor based. I've also noticed RDI advertising a lower cost
aluminum block as well.

I recently waited 7 months to get a FRPP block through RDI (I just got it last week) and want to avoid that if I can in the future. I was under the impression that RDI was the only place to get aluminum blocks...

Thanks.

Thanks so much for sharing all the pictures! I really appreciate your help and efforts.

The Fontana block has been around for years and was designed for the rigors of sprint
car competition. One difference between it and the RDI is that it uses a Cleveland
oil pan though the rest of the oiling system is Windsor-based.

P.S. Thanks for the pictures.
