clutch rod difference 352/428?
I'm still plugging along with my engine swap from a 428 to a 352 in my 66 F250. Everything is installed and fits fine except the clutch rod seems to be way too short. I have adjusted it as far as I can go without it falling apart, and still I cannot get the clutch to completely disengage. I am using the clutch rod from the 428 setup, along with the existing (428) bell housing and transmission. The clutch fork looks fine, all clutch parts are new. Is there a length difference between clutch rods for the 352 and the 428? If so, does anyone know the part number I need for the 352 clutch rod?
Thanks again. We're making progress, I think. If anyone wants to see what the installation looks like so far, take a look at the attachment below.
Thanks for all your help, folks.

Looks good. The question is not really capable of an easy answer because they didn't install a 428 in trucks from the factory. You are simply going to have to makeshift something longer.

You may have to use a different throwout bearing collar there are two that I know of a long and a short. Using a short where a long should be will give you the problem you describe. Using the long where a short should be the clutch will not engage and you won't be able to get any freeplay. If you have an open bottom bellhousing you can look with a light the long one will have about 1/2" between the release fork and the bearing, the short will look like the fork is right against the back of the bearing. Anotyher possibility is the Packard pressure plate you mentioned in your other post may fit but still not work because of the travel riquired to engage and release the clutch.Good luck, Rich

Good points. I am using the clutch rod from the prior engine, which was a 428 (not original, I know), so perhaps I just need to find a correct original clutch rod from a 352 truck. The one that was used on the 428 installation may have been shortened for that swap, I don't know.
I am also using an identical throwout bearing to the one that was in the truck with the 428 - I did see the other choice at the parts place when I bought this one, but it seemed very light duty when compared with the one that was in it. Perhaps I should have switched to the other size, but it's a big pain in the butt to change it now.
For the present time, I have made up a 1/2 extension for the clutch rod, and the clutch is working fine now. The pressure plate seems to be the correct one (11" Long clutch), even though it came from a Packard, it has the same dimensions and throw as the old one, so I think that is OK.
I'll see how it goes with the rod extension - I may not be quite done with this fiasco yet.
Thanks, all, for your advice and counsel.
