390 Replacement For 352 Help
My 65 F100 has the original 352 in it. To make a long story short, I am going to pull out the 352 and replace it with a 390. I know I can turn the 352 into a 390, but I want to keep the 352 as is, because it is the original motor.The plan is to store it away to return the truck to totally original condition some day.....
I am going to a local wrecker to get a 390 to rebuild for $300. I just wanted to confirm that a 390 should be a direct bolt-in for the 352. The truck has a
C4 automatic transmission.
I beleive the 390 was available from 1968 to 1976. Does it matter what year I get to rebuild?

I' thinking the truck likely has a Cruisomatic tranny but a sure someone will correct me. They always do...lol Yes on the drop in fit. Specifics on the year's differences will have to come from the more informed.

My O, I would go with a 360 because of the better heads and rebuild it out to a 390. While I was looking I would be seeking a reverse image 105 block too, but that's just me.

C8AZ-6049-M .. Cylinder Head / There were several different casting numbers used, but there is only one head.
These same heads could be on a 352 engine, because beginning in 1968, Ford replaced the heads used on 1965/67 352's with these heads. They also supplied 1000's of these 360/390 heads to their authorized rebuilders.
No F100/350 (or passenger car) w/a 352 ever came with a C4 transmission. 1965/67: MX Cruise-O-Matic = 14 transmission pan bolt holes (C4's have 11).

BIG warning! Make sure wherever you get it from, have them pull the pan, and make sure the crank is a 2U or 2UA - that's for sure a 390 crank.
Like many of the guys here say, on sale day, a 360 becomes a 390 REAL fast
If you mean "better" as in hardened exhaust seats (D2TE heads), chances are any 360 with a decent amount of miles on it will have "unhardened" those seats by now anyway. Induction hardened seats get soft after getting slapped by the exhaust valves for a long time

Regardless of the C8AE or D2TE casting numbers, there's only one part number for those heads 1968 thru 1972: C8AZ-6049-M.

I was thinking D2 or D3 heads. Chances of finding a 360 are higher than most others on any afternoon hunt. IMHO
Bill where did your number C8AZ-6049-M come from? I can't find a reference to it, not even Google search.

The C8AZ-6049-M is a PART NUMBER with which you order parts out of the catalog with. The numbers you see physically cast into heads are CASTING NUMBERS and are not the same.

1964/72 FORD TRUCK PARTS CATALOG / Text / Section 60.7 / Page 5.
and...
1965/72 FORD PASSENGER CAR PARTS CATALOG / Text / Section 60.6 / Page 5.
Looks like Google should have the parts catalogs, too!
Both of these catalogs are available on a CD from hipoparts.com for less than 23 bucks each.
As original, on loose leaf paper, the truck parts catalog has 4849 pages of text, 1961 pages of illustrations, which are then split into two huge binders.
Try balancing these two elephantine sized parts catalogs in your lap while typing numbers on a laptop computer!
Now you know why I use the CD.

Mebbe it's because I've been doing this scheiss for over 35 years.
It also helps when one has over 10K basic part numbers memorized.
Now, there's no need to look at dozens upon dozens of pics to find the number for a specific part.

If the power goes off, I can't come here and raise he!!.
Besides the CD, I have two complete parts catalogs on paper.
I don't care if the power goes off or not...I can still find the part number. If at night, all I need is coupla kitchen matches.
Besides, who needs the dang parts catalog?
Bob, I can walk around your truck and reel off, from memory, just about any part number on your truck, including the sheetmetal and trim, most of the mechanical components. I did just that on several trucks in front of about a dozen ppl at the WestNats in Yorba Linda.
There's a picture of me pointing out the part numbers in the SoCal/Hawaii Chapter forum: Thread "Post Meeting Report" / Page 1 / post #12 / first pic / the fat guy in the red/white shirt.

If so, than the D2 heads I pulled from my '74 highboy would have been out of date and incorrect... just curious.

1973's with T/E, all 1974/76's use different heads.
