installing a big block into a 67????? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi Gang,

Is there anyone here that has a true 67 1/2 truck that they have installed a big block into?

I want to find out a few things before I start working on my new 67 of which I have a 402/T400 combo that I want to install in it.

For example, what mods did you have to make for this to work? I know that the width of the top of the frame where the motor mounts go, needs to be trimmed back as the 72 bb mounts I have do not line up. Also, does the T400 fit under the cab that has a low hump or do I need to cut that out for a high hump?

Also any other tips?
