1969 Ford Cleveland heads
 

Aren't the 2 bbl & 4 bbl heads the same? The difference in compression is from the dished verses flat top pistons.

thanks in advance,
John

The 351 Cleveland didn`t come out until 1970. The 351W debuted in 69. As for the Cleveland heads, the 70-73 4 barrels had larger valves and ports than a 2 barrel version. The 70-early71 4v heads also had smaller combustion chambers than the 2 v or late 71-73 4 barrel castings.I heard that there was an oddball "smaller" 4 barrel head towards the end of the 351C`s production run, but I`ve never seen them myself.
As for the 351W heads, I believe the heads are the same for 2 or 4 barrel applications.

The only Cleveland style cylinder head in 1969 was the 302 Boss head.

Re: 1969 Ford Cleveland heads
 

The '73 Cleveland 4-bbl heads had the large ports, but the same valve sizes (2.09/1.66) as the 2-bbl heads. All had the large combustion chamber.

HHmmm, lot of years since I even touched one, but;
2bbl 2.05 int 1.65 exh open chamber ALL (70 some cc I think)
4bbl 2.19 int 1.72 exh open chamber police int head 71-74
4bbl 2.19 int 1.72 exh close chamber adj valve train boss 351 1971 only
4bbl 2.19 int 1.72 exh close chamber hyd valvetrain 351 CJ 1971-74

Memory being what it is, I'm thinking the hyd 4bbl CJ head and PI head might be reversed.

And yes when your running a stockcar and they have a cyl pressure rule, one open chamber and one closed chamber head will give 155psi(165limit) and the open will give 120....until your caught 5 races later...don't ask LOL!

Re: 1969 Ford Cleveland heads
 

Oh yeah, something else, the 2bbl intake can fit a 17 year olds 3 fingers and the 4bbl will fit 4 fingers to the knuckle! (like sewer pipes) LOL!



good times.....

Re: 1969 Ford Cleveland heads
 

ACTUALLY the 73 and 74 heads had the 2.05 intake valve and 1.65 exhaust valve. but if you could talk NHRA into letting us run the 2.09 intake valve pleaese let me know!!!!!!!!!!

Re: 1969 Ford Cleveland heads
 

Just have uncle Carol or uncle Bill write a letter. You of all people should know that...

Re: 1969 Ford Cleveland heads
 

Actually Duane, it's 2.05/1.66.

Re: 1969 Ford Cleveland heads
 

I just looked up the guide to see how close I was. (blueprint guide won't open at work)
ALL 4BBL HEADS ARE 2.19!! I don't care what the guide says as obviously it's wrong. I used to run 454 chev valves in my heads because in the early eighties the chev's were like $4.00 a piece and the fords were $12.00 or something like that. I had D1/D2/D3 heads, if they were 4 bbl, they had 2.19's.

Has nobody run a 73 cleveland? How come this has never been protested or the issue been raised?

Yes the 2bbl's were all 2.05's x 1.65 (guide shows 1.66) The 2.09's have longer stems heehee same diameter stem though.

Re: 1969 Ford Cleveland heads
 

1973 4-bbl heads had the smaller valves. I just put a set on a friends '73 Mustang convertible and they were the small valve heads. I also have another set in the garage. So NO! All 4-bbl heads DO NOT contain the larger valves. All CLOSED CHAMBERED 4-bbl. heads contain the larger valves. The D3ZE-AA heads came in both large and small valve configurations and that casting # is the legal replacement head for all open chambered 4-bbl heads. Rarely, the small valve versions show up on e-bay. In fact, there is a set of '73's on e-bay right now The ad says they have the 2.19 Intakes, but it's obvious they still have the 1.66 exhaust when they are compared to the '71 large valve heads also on e-bay. The space between the valves is significantly larger on the '73 heads.

Re: 1969 Ford Cleveland heads
 

I guess I'll go to bed tonight a little less stupid! LOL! I've never seen or even HEARD of small valves in a 4bbl head. I had dozens of pairs stacked like cord wood years ago. Any time somebody had "an old cleveland" laying around I'd scoop it up because of the volume of cranks I was going through. (before I learned about the oil line in the valley trick). I grabbed 2bbl and 4bbl engines. Never saw or even heard of small valved 4bbl motor.

Was canada different???

Was I in a sheltered community??

very strange/suprising....I suppose now somebody will say the 351W came with a 4bbl in certain years too! (Just kidding)

Re: 1969 Ford Cleveland heads
 

Yes, 1969. Check the NHRA Blueprint sheets.

Re: 1969 Ford Cleveland heads
 

Psst, I was kidding...I know...it was a joke...69 and 70 actually...

Re: 1969 Ford Cleveland heads
 

(before I learned about the oil line in the valley trick).
That trick would be illegal in NHRA Stock...

I'm sure Vern is lovin' you guys right now! But then again, maybe he does run the small valves?

Also, SSDiv6 is correct. 1969 351W with 4bbl factory rated at 290 HP. I had one in a '69 MACH 1 with a 4-speed in high school. Always beat the Clevland racers and always had to prove it was a Windsor! Always thought it wouldn't be as bad as people say in Stock.

Re: 1969 Ford Cleveland heads
 

The NHRA Blueprint sheets show a 351C @300 HP for 1970; does not show a 351W-4-bbl for 1970.

Re: 1969 Ford Cleveland heads
 

Thats right, 1969 was the only year for a factory 351W with a 4 barrel in a car. In 1970 all the 351 4 barrel engines were C`s, although both the W & C were available as 2 barrel engines.There were plenty of factory iron 4 barrel intakes made later than that for marine 351W engines, and Ford did make a 351 HO 4 barrel engine in the mid 80`s, but only in trucks. As for the small valve 4v Cleveland engines, I used to own a 73 351CJ engine, and I was certain that it had the open chamber, large valve heads, were ALL 73 heads supposed to be small valve?

Re: 1969 Ford Cleveland heads
 

Not that it adds alot to the thread but I had an F-350 in 1985, it had a 351 W w/ a Holley 4 barrel.

Re: 1969 Ford Cleveland heads
 

The 351W HO with 4 barrel was avalable in the police cars also. the 73 4 barrel 351C open chamber head had a smaller intake valve than the 72 head that was prone to cracking between the intake and exhaust valve.

Re: 1969 Ford Cleveland heads
 

Ever see the Australian 351C 2 barrel high compression heads? Ford North America was asleep at the wheel back then. I'd like to see a 351W run in Stock with that little tiny carb on it.

Re: 1969 Ford Cleveland heads
 

With the appropriate HP factoring, an engine with a little carb can be a contender.

Yes sir, that is the key to all Stock Eliminator Racing: Accurate factoring and no cheating!

But I still would like to see how quick a 351W with the (what is it a 490 cfm carb?) could run.

Re: 1969 Ford Cleveland heads
 

I owned a 1970 Mach1 Mustang with a 351C and it was rated 300 HP from the factory.

Re: 1969 Ford Cleveland heads
 

What about a 69-70 Shelby GT350? They have a good aluminum intake but i'm not sure what carb.

I'll bet with the right amount of money it can be a Holley 850. :D

Re: 1969 Ford Cleveland heads
 

Tom,

Please define "the right amount" part. Many of us are on tight budgets but if we combine our allowances...
