Trouble installing BB in truck - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Maxian · 06-01-2013, 02:25 AM

I'm having trouble installing my BB in my '69 truck
Using factory BB tower stands and using the correct engine side mounts.
Just doesn't seem to fit. Like the engine is a 1/4 inch too wide.
I can get one side to bolt up, but not the other. I can get close, just can't get both to line up.
I've loosened the stands to see if there was any play, but will only adjust front - rear.
Almost as if I shaved 1/8 off one mount it would settle in correctly.
Any thoughts or ideas regarding this ? Common issue ?

Thank you

I would guess that your frame is tweaked. Common with these 40+ year old trucks.

Not tweeked. Truck in family since 1969.
Never wrecked or abused. Az truck, no rust. Frame pristine.
Hmmm

Ok, figured out how to add a picture.

Even without abuse, I would still suspect normal wear and tear, given the age and the fact that it is not that far off when you try and set the engine in place. Is it possible the mounts are tweaked slightly?

Brand new GM mounts.
Truck might have 40k at most,

Maxian · 06-01-2013, 03:04 AM

Any suggestions ?
I was thinking of just shaving one mount down ????

Can you take a shot of each side from the top?

Desperate times require desperate measures, but Pepto is for settling stomachs not engines.

is the motor hanging on the lift?? // engine weight on lift an a couple of large screwdrivers is the way i've been lining up engine mounts fer years

We used '74 stands and mounts when we put the '74 454 in my '69 frame and it settled in nicely.

^^^X2 and loosen everything up well first.

Had some issue shooting BB 305 V6 mounts. I loosened mounts for wiggle room. I moved engine lift chain to front of engine so I could rock/list engine back and forth. Shot it then snugged er down.
