Bell crank question

[cigar-]

I am doing a motor replacement in my 71 half ton. Originally the motor was a 250 inline six. A previous owner put a 350 V-8 in the truck. The motor was bad, I bought a new one and the install will hopefully be this weekend.

The bell crank that came out of the truck shows the arms having been cut and re-welded. The bell crank I have has a slight bend in it. I bought another crank from a guy that dismantles these trucks and it came from a V-8 truck. The one I got is straight. The new one is about one half to five eighths of an inch longer.

Has anyone done this change out and encountered the same issue? I can only assume the old one got modified for some reason (to possibly clear the exhaust manifolds which have been changed from original). The original drivers side exhaust originally swept in and back. The one that came on the truck drops straight down. I plan on going back to the original configuration.

Any and all help is much appreciated. Thank you. I can and will post photos of the two bell cranks if that helps.

Please do that.

The only issue I have is that the mount is different on the frame between the 6 and 8's. That has made me have to mod the Z bar.

Smitty,

I had a funny feeling there was a difference. Can you tell me what mods you had to do?

I put a welded up one in mine, but I heard you can take a V8 one and cut it down and it will work.

Hopefully someone will read this two day old thread......

So that I get things right, is there anyone out there in Southern California with a C10 truck, V-8 motor and a stick shift?

I would like to have a look at the position of the bell crank bracket and the bell crank itself. Maybe I'm the dumbest guy on here but fitting the pivot ball and crank are giving me fits. I have three bell cranks....one that us bent (came off the truck), one from a V-8 C10 and one from what I don't know.

I need to see which one works best or correctly. Based on a previous reply above I don't know why Chevrolet would mount the bracket on the frame in different locations on V-8 versus an inline 6. Yes, I know the motors are different size and design but it still perplexes me!

I appreciate any and all help.......

There is also two positions that the engine sits in depending on which engine, and whether two or 4 wheel drive. If you look at the frame where the engine mount stands bolt on you will see an extra hole either in front of the stand or behind it. The engine can be moved that far back "or" forward. I will see if I can find a picture. I know there have been some posted on here.

The bottom one is right the other has bent bent to fit more then likey they did not move the motor to th v8 spot or if the did to move the brakets to line up
