Bought a 86 F250 cheap & my buddy said it had a 460, the door tag said it should be a 460 but the valve cover has a 370 sticker & the only number I saw on the crank was 1VAB, rods were C9AE, block is D9 & I couldn't see the numbers where I usually see them on the heads....

Isn't a 460 crank suppose to be 2Y or 3Y something, or did this change with 79 & up...

Anything else I should look for so I don't have to take the head off & measure the bore & stroke(what should it be for a 370??)

I sure could use some help, I'd really like to do a mild build on this if it is a 460 with all the great info in this forum...

Thanks

 

Yes the 68 to 78 460's were 2Y and the 79 - up were 3Y.

Sorry, I don't know what you have.

 

You'll have to pull the pan and get the crank ID from the #1 throw. How did you get the rod numbers?

 

I pulled the pan off & turned it over & all I could find was 1VAB and it looks to be stamped on the first throw & not cast....maybe I need to look harder??

Thanks for trying to help me out...

 

Goerge......I think he pulled the pan, he said 1VAB was casting number. I can't find that casting number for the life of me. If I'm not mistaken it should be on the 3rd throw, maybe I'm losing it.

 

Yeap I'm losing it!

 

I found SM-D I think stamped on the 6th throw & it looks like she's been apart before - the rods & ends are numbered...

Also, I found D9TE 6110 B2A on the inside of the pistons...

Any ideas???

 

I lost it a long time ago but I sure don't recognize that crank number. But I don't know anything about the 370, so that doesn't mean much.

What's the bore size?

We need a 370 person on this.

 

Found some info on it.

BORE STROKE ROD

4.050 3.590 6.605

Seem it uses a 429 crank with standard 429/460 rods.

 

I found this info on a rebuilders website:
1979-91 370 HD
Block Code: D9TE-BB
Head Codes: E9TE-FA, D6TE-FA, E8TE-FA
Crank Code: 1VAB
(Spec. if Head is 2 Barrel or 4 Barrel)

and this info from another's:

Truck is VIN Code H.
79-85 2 BARREL CARB. TRUCK. CASTING# D9TE-FA
79-4/85. TRUCK. 4 BBL CARB. CASTING# D9TE-HADFC1!!

5/85-90 COMP ENG TRUCK ONLY! 2 OR 4 BARREL CARB.
5/85-90. 2 OR 4 BARREL CARB. E6TE-FA, GA

I thought the 370 crank would have been the same as the 429HD crank, but found these codes for the 429 on the rebuilder's site:
429
Block: D9TE-AB
Heads: D9TE-FA, D9TE-HA, E5TE-HA, E6TE
Crank: D9TE-EA 1979-85 429 V-8 H.O., Truck Only, 1 3/4" Crank Neck

What I would REALLY like to know is if 370 rods are the same length as 429 rods? Or are they unique?
Could the 370 use the same pistons as a 390/391? They are the same bore.

 

As to the rods being numbered - that's probably from the factory. The rods in my 2.8 V6 were numbered and I'm quite sure it hadn't been apart before.
