5.0 heads on a 69 302

[D.Hearne]

Now we're really getting somewhere, seems something gets lost in the writing sometimes. Who carries the other balancer (vbelt) should I do the engine swap?

Some of the classic Stang parts vendors sell these balancers.

check your casting numbers i have worked on alot of Vic's that had E7 heads so look at them and see first. If they are E7 heads they will work with your current cam/lifter setup and you will need a 6.800 pushrod.

Ok I am going to try this. I have a set of E7 heads off a mustang and they have the original rocker arms. I will be putting them on a 1969 302. Is there anything else I need to look for? Thanks.

I believe that if you are only going to swap the heads, the primary difference will be with the rocker arms. I.E. Pedastal mount as apposed to the earlier style rocker mount.
Proper push rod length will be a concern.
Buy an adjustable P/R checker from Comp Cams. They are in expensive and a very necessary tool to have when you get into more perfromance applications.
Other than P/R length, I BELIEVE all else should remain the same.
I had a major learning curve about what 'should' fit, and what needs to be measured. Measure everything, twice.

Well finally put heads on car. Well the pushrods from the 69 heads are to long. So I bought a set of 6.80 inch long pushrods and well they are to short. They are melling part number mpr-279. Does anyone know what the correct pushrod part number is? It was really disappointing after all the work. Any help would be appreciated. Thanks

The pushrods you need are the ones used from 78-84 in the 5.0 Stangs or the 85-91 E or F series trucks and vans.

1988 Ford truck with a 5.0 shows a mpr-281. I went to autozone.com and looked at the different part numbers for 1969 and it show mpr-281 and mpr-279. The mpr-281 are my old ones and the mpr-279 is the ones I just bought. They are to short. The mpr-281 are to long. I am lost.

How are you determining the length?

Ford's 5.0 book lists a length of 6.88" for your application. Comp Cams p/n 7631-16 (magnum line)or 7831-16 (high energy line) both are listed as 6.87" or 6.9" Summit brand p/n is SUM-G6413. Crane pushrods p/n 36661

I'm with him. For $20 you can actually determine the correct length pushrod. All the parts in an engine have tolerances, which will effect the proper length. Also, any of the parts could have been cut in the past.
