Moving 1972 4x4 engine crossmember - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am going to be putting a 454 in my 72 k10 and from researching the best way sounds like moving the engine crossmember forward the the next holes. Here’s the question, when I try to slide it forward I can’t get more than an inch before the frame narrows and the crossmember gets held up hitting the sides. Is this normal? Everything I’ve read on doing this never mentions narrowing the crossmember to accomplish this. Also the only “forward holes” on my frame are on the drivers side top. Is that also normal? I understand that I need to drill some holes but am I missing somthing? Thanks for any help.

Nope, you're not missing anything. Drill the holes and grind down the x-member a little. UPGRADE to 7/16 bolts with locking nuts

The only real hassle you'll come across (if you have an automatic) is getting the linkage from the column to the trans correct as it comes close to the front shackle with the engine coming forward, so you'll have to get a little creative
