Hello all. Well I pulled off the intake manifold, rockers and pushrods. Getting ready for new cam and a 4v intake and carb. As some of you may already know I have a 65 f100 352. The motor has 140,000 miles and was rebuilt 40,000 ago. The valves look good as do the springs. My question is: the casting numbers on the cylider heads reads C4AE 6090G from what I can find these are not the original heads for the 352. The intake ports on the heads measure 2.34 tall by 1.34 wide. From what I can find these heads came off a 427 CJ motor. IS this correct? Are these good heads to have? Will these heads play a factor into cam, intake and carb choice?

 

They were a common production head for that year; stock size valves. The G heads do have a reputation for good flow.

Just off the top, the 427 had a H (?) suffix. I'm sure others will chime in on that.

Yes those are good heads. And they are not from a 427 or 428CJ. They are more than likely the stock heads that came on the 352.

 

You are exactly right! C4AE-6090-G heads = 352 = 1965/67 F100/350.

For service replacement, these heads were replaced by Ford in 1968 with the 360/390 heads.

1963/65 427 cyl head casting number: C3AE-6090-J

Ford never applied the terms: Cobra Jet or Super/Cobra Jet to 427 engines.

No 428's till 1966 / No 428 CJ or S/CJ's till 1968.

 

Bill, You are right, it was Carroll Shelby that caused all them grown men to get weak in the knees and drool and slobber all over themselves at the mention of 427 anything.

Info appreciated, thanks much.

Dont kick youself too hard.I just let a complete C3 390 from a T-bird slip by for $125 on Ebay last night. 70 miles from me and no easy way to go pick it up right now. I do have a lead on a '65 352 down the road. Just hoping the owner wants little for it.

 

Some port clean up and a little bowl work and some CJ size valve's...C4"s will flow as well as out of the box Edheads......Make sure to check your intake to your heads for ports match....and also port match your gaskets.... JMO

RJ

Oh Bob, you better watch about getting Larry nervous!!! He'll bring out the Wagon and spank you with it at the track.....There can be nothing so embarrassing as to have a 4 dr. wagon put your *** on the trailer !! LOL.....

I think its pretty neat!!!

You wish and so do I that we had those C4G heads you had ported with those high bench flow numbers of last year Russ. Someone out there is happy with 'em I bet.

 

speaking of this bench flow system. Does any machinist have this or is it something you find only at Dyno houses or ? Any idea on cost to have a set tested?
