I have a 429 in a f250 and im havin trouble finding out what 429 it is i know it is a none egr, 4bbl, with dove heads i wastold two different stories on what the motor is out of 70 mustang or a 70 LTD any help would be greatly appreacited

 

If your engine is not a Cobra Jet, Police interceptor, or Boss, the 429/460 engines are pretty much the same with few differences across the years of production. The later engines (after 72)had larger combustion chamber sizes to lower compression.

Aside from the above mentioned exceptions, the blocks, cranks, rods, etc. are virtually the same throughout the life of the 385 series engines.

The casting number for the heads from 1968 - 1972 (except for the above noted exceptions) will be one of the following, they all have the same chamber size, port size, and valve sizes.

2.09" Intake Valve, 1.65 Exhaust Valve, 2.18 x 1.87 intake port size, 1.99 x 1.30 exhaust port size,
88cc chamber

casting numbers:

C8VE-A, C9VE-A, DOVE-C, D3AE-A2A

SCJ and PI casting #s

D0OE-R, D2OE-AA, D2OE-AB, D3AE-FA

If you find that you have a CJ, SCJ, or PI engine , I can post the specs for these as well, right now I am too lazy to do so for no good reason!

<< BTW, a 460 is nothing more than a stroked 429....>>

 

look for the block casting numbers. theres a couple threads on here to decode them.

edit..never mind! see above

 

i do have the dove-c heads. so is that just the standard run-of-the mill 429?

 

Only 429 in a 70 mustang was the boss its out of a ltd.Yes the dove heads are the normal ones there not bad but get cobra jet heads and a good cam you got a mean big block.

 

I got my information from "Ford Engine Parts Interchange", they like the 429/460 in it's stock form. They say that the engine is great, tough, makes good power, and that a CJ, SCJ, or PI engine is a nice bonus, but not something needed forstrong performance.

You might check into some of the aftermarket heads and other partsoffered for this engine as well.

 

you do have good heads though, they are much much better than the later model 429/460 heads

 

thanks for the help guys... i have to change the cam in it,, the exhaust lobe on the #5 cyl is pitted real bad and wore the lifter down and it collapsed so while i have the the cam out im gonna change the head gaskets and get rid of the stock intake and i needed to know what engine i had because the intake i have picked out is for a nonCJ only... thanks again

 

also does anyone know the torque specs and tightening seq. on my intake and heads???

 

yep
