1. Putting together a 408 strker Cleveland with Scat crank. Do I need a spacer between the crank and the timing gear? If so, where to source?

2. Is there a oil scraper or screen used over the front of the crank, inside the timing cover? Where to source?

3. Do I require a Scat or other windage tray?

4. My block is bored to 4.020". What size head gaskets and which are the best brand/type? Approx 11:1 CR.

Thanks in anticipation.

There is some difference between a Cleveland crank snout and other SBF cranks, and I think the spacer you mention is required to use a non-Cleveland crank in a Cleveland. I have the same issue and need to address it soon. Dan Jones (and I'm sure others) knows the details.

You may be able to figure it out by looking at any missalignment of the gears.

"If" Scat is still selling Windsor cranks for Cleveland applications then the answer is yes you will need an assortment of specialized parts for that application.

If memory is correct, I believe Scat now manufacturers Cleveland specific cranks to Cleveland dimensions.

If the crank has a Windsor "snout" then you will need:

Specialized camshaft timing set
Crankgear spacer
Windsor harmonic balancer

My advice is to buy a "kit" from MME, Mark McKeown will assemble a kit that will have all the right parts. Mark uses specialized pistons designed by him for this application, featuring an off-set wrist pin to reduce thrust forces on the cylinder wall. Highly recommended. You get a superior kit, one stop shopping, assurance you are getting the right parts from somebody who has built many 408 Clevelands.

Victor Reintz performance head gaskets. I believe they were
originally designed for marine applications. For 351C's, the
part number is 3502SG which is Nitroseal material graphite on
steel core. No sealer or re-torque required (though re-torquing
it can't hurt). Don't confuse the 3502SG with their rebuilder
type head gasket (paper mesh on steel core) which is Victor Reinz
3502 without the SG. Victor also has a headgasket for higher
cylinder pressures (nitrous or boost), p/n 3446 for 351Cs but I've
not used any of those. If you can lay your hands on carbon impression
paper. It can be put between the head and block to see if your heads
and block are sufficiently flat to ensure a good seal. When using
premium multi-layer steel gaskets, a finish of 15 microinches Ra or
less is recommended. Victor is a German company, I believe, so you
may be able to source those local to you, rather than ordering from
the U.S. If not, I can get you a set.

There's an oil slinger. You'll likely need to nick it from a
used engine. I don't think I've ever seen a reproduction part.

What oil pan are you using?

Only the current 9000 series cast steel has the 351C snout and does
not require the spacer. The earlier 9000 series and all (non-custom)
Scat 351C forgings do require either a snout spacer or a timing set
with integral spacer. Scat sells a timing set with integral spacer
but beware it may use the suspect Rolon chain from India.

The crankshaft oil slinger is part number D0AZ-6310-A.

There are 3 sources I normally check for obsolete 351C parts:

1. Ford: Although 351C parts are obsolete, the 351C shares many parts in common with the 400, which was used in Ford pick ups in the late 70s and early 80s, and in the large Ford sedans too. Many parts are still listed for the 400. I normally reference a 1978 F250 with a 400 when I go to the Ford parts counter.

2. Perogie Enterprises of Hightstown, New Jersey: The business is owned by the Porubski's. Their pricing is expensive, but they have always had the part I'm looking for. I've been doing business with them since the early '80s, never had a problem.

3. DSC Motorsports of Anza, California: Dennis Carrico does a lot of 351C parts business on eBay, he has a lot of the little parts that are needed to assemble a motor. I've purchased a few things from him, never had a problem.

I'm sure there are other such sources, these are the ones known to me. I have an oil slinger on the shelf at this moment, I purchased it from Perogie Enterprises.

Thanks guys,

Dan's mailed me privately also as I'm always pestering him. Heck, he has my CHI heads for the forthcoming dyno day.

Cowboy, I'm in London, UK so as you can appreciate not all US shops are setup to deal with International orders.

I think most of Euroland deals with either Summit or Jeg's. If they don't stock the parts we need then it's normally a little more trouble sourcing parts.

I will locate your NJ parts store for a scraper.

I already have the bottom end built. My complete stroker kit came from one of Dan's contacts , AD Performance in Redmand, WA. I'm very happy with the kit, however I still need the small parts I'm enquiring about as my friend and engine builder is having to overcome all these obstacles!

If I ever purchase another engine I'll go with one ready built and dynoed. My way is the wrong way!

Dan,

I forgot to answer you question re oil pan.

I'm using a stock size Milodon pan with some baffling to stop oil surge.

Couldn't afford anything better! Anyhow, the Longchamp's not worth a dime:-)

Phil

The spacer you need is 0.300 inch.
Romac and JP ( both aussie companies) manufacture timing chain kits that have the spacer built in to the lower sprocket.

Phil,

I have a Scat 408 stroker crank in my Cleveland. I use a Cloyes Hex-A-Just Timing Chain Set and Milodon Windage Tray.

My engine is powerful and bulletproof (well, so far). Click on the link below, click on the DT logo and go to "details" then "engine build" for a list of all the parts that seem to work well for me.

Thanks again guys.

I'll give Summit a call now as I also need a few other parts.

I'll call DSC afterwards for any remaining parts. OK on the Aus parts, as a last resort due to time.

I want to complete this engine as soon as possible.
