Firewall question for LS swap guy - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Law79 · 10-28-2013, 11:31 PM

Hey gents. I am about to start the cab body work on my 69. I plan on shaving the firewall and would like to know if there is anything in particular I should be doing. Currently the frame is PB Extreme dropmember and I still have a perfectly good running 350/350 setup. I just want to do the mods for the LS swap just in case my engine craps out on me. Not really wanting to do body work twice if I don't have to.

Also I would like to see if anyone knows of a good fuel cell that is set up for carb with the efi option. I like this one but don't know if it'll support what I'm trying to do.

Several years ago there was a build thread on this board by EricD entitled "Silver Bullet". That was a 67 stepside with an LS motor. Very nice thread and lots of pictures. Use the search engine at the top of the page after clicking om the 67-72trucks.com radio button and entering "silver bullet" in the search box..

There is the LS/LSx motor forum on here as well.

Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
