I would like to know more about this engine. Bore & Stroke and what did they come in ?

 

Bore is the same as the FE 360/390 at 4.05" Stroke is the 429's @ 3.58" Only used in meduim duty Ford trucks like the F600, F700,etc. Rods are shorter than the other 385's. Almost nothing is worth interchanging to a 429/460.

 

Hi and Welcome to FTE! Please take a moment to check out the Guidelines, they contain important information that you'll need when posting on the site:

I've moved your post to the 385-series forum where you should be able to get more info.

 

ford came out with the 370 2v 370 4v and 429 4v in 1979 to replace the 330 361 and 391 from 1978 back 1964 .
the 370 came in dump truck's school buses f600 f700 b600 b700 they was never put in a pickup or car.

 

I found a late 70's model truck that has what I think is a 3704V. Would the manual fly wheel fit on a 460? I don't think it's a 429 motor. It appears to have the longer snout on the end of the crank. Not sure if the 429 truck motors had this or not.

I was told when I was younger that these motors had steel cranks and if you turned the crank snout down you could run it in a regulaer 385 series engine. Any truth to this?

 

actually only the 429 truck motors had the steel crank, the 370 had a cast crank (with the rare exception of coarse of one that was accidently put together with a steel crank because someone happened to grab that instead, Ford was good about those types of things and almost nothing is an absolute)
One major advantage to grabbing a 370, that the block is just like all the rest of the D9TE blocks with the exception of it is only bored to 4.05 instead of 4.360, so if you happen to have say a good rotating assembly out of a standard bore 460 you can take that 370 block and bore it standard adn put the rotating assembly into it, disclaimer here though you can only use the externally balanced rotating assemblies as the earlier internally balanced units with not work without major clearencing. This can be a major advantage to guys that are working in CID limit rules racing that say have to stay below 465cid or some stupid number like that (rules that are intended to keep the BBF guys from bieng able to rebuild thier motors and encourage teh chebbie guys), so you could build a standard bore 460 with performance parts and not have to pay big money for a new block.

 

I don't think this is the case.

The 1979-up 429/460 blocks are casting number D9TE-AB, while the 1979-up 370 block is a D9TE-BB casting. There is not near enough material in the cylinder walls to bore this block to 4.36", as it was engineered to have a 4.05" bore and can not be bored anywhere near .300" over.



Wish I had a picture with the freeze plug removed so that y'all could see the Grand Canyon gap between the cylinders.

Paul, I rarely disagree with you, and guess I haven't seen the BB designation blocks so it might be different, but we just got done last spring building a 429 using a 370 block and punched it to 4.360 ( the guy had a set of standard bore forged 429 pistons) so that might be something to check on because I know that atleast some had the regular D9TE-AB block.

 

Wouldn't surprise me at all if Ford used a D9TE-AB for a 370 when there were no 370 blocks to keep production moving...but a D9TE-BB block cannot be bored to 4.36"...none that I've seen.

Also, your info kills my typical search technique of looking for 429 truck cranks, now knowing that I may indeed buy the Lima engine from a dismantler just because it's a D9TE-AB block...only to find a cast crank in it.

Don't feel bad Paul that is why this kid bought this engine, he thought all the truck engines had the forged crank (didn't bother to ask me before he bought it) and then calls me up and asks why it has a cast crank in it.
