Well, she fits now
Well a little of this, a little of that and now that bad boy fits!
As some of you know, I am swapping in a 454 in place of the 307 and ran into major firewall problems. In the end I increased the body lift a bit and as you can see made a few minor firewall mods.  My plan is to at some point go in and move the engine forward so I can go back down to the 2" body lift. This combined fix gets it where the body guy can get done, I can enjoy the truck and then when I'm ready for another project I can go in and move the engine forward. To avoid having to move the engine forward the firewall mods would have ended up being pretty severe. I really can't see how some people are able to do a 3" body lift and light massaging on the firewall, though I know they have as I have seen pics.

Holy crap. That is some severe surgery there. I hope Doctor Boz-all was licenced in the state of KS. If not maybe you should sue for malpractice.
 I did not envy the position you were in, I suppose a 292 was out of the question?

that looks pretty clean, how are you planning on patching the holes? it is kinda weird, because i got a 454 in mine with no body lift and i only had to bash the firewall in a few places for it to fit. keep the pics coming thanks

I haven't worked with BBCs much, are the newer motors that much bigger than the original 402s that went in these trucks...???

bigvinnie, the 67-72 4wd's did not have a big block as an option.
CPNE, no sawzall here, just a good ole cut off wheel but I guess that probably does fall under Doc Boz-all territory. (At least my dash remains uncut!) With carpet this mod should not be too noticeable - unfortunately I just didn't have much in the way of options that could be done at the moment. Ryanroo - the pieces that were cut out will be built up and outward a bit to cover the holes.

I didn't know that, does a 2WD truck have a different firewall to accomodate the big block?

the firewall is the same on the cabs, just the eng positioning is different for the BB 2wd trucks. 4 wd sb sits in I 6 position(for 2 wd), the factory sb (2 wd sits about 3 1/2" farther ahead than the I 6, 2 wd , or sb 4wd. the BB comes somewhere tween those two spots on the 2 wd truck. crazyL

I will have to do the same thing to my '72 K5. Already test fit the 402BB and "rough" cut the needed clearance. Fits like a glove.

I am probably going to graft in a throttle cable setup rather than the throttle rod setup that this truck had.

You may want to look at Lokar's Eliminator Floor Mount Gas Pedal
FMG-6097 This bolts to the floorboard and has a cable assmbly that mounts under floorboard. I dont think you will be able to draft any stock setup, http://www.lokar.com/thottle_assemblies.html

You are a very brave man! If your brakes go out, you will have a Fred Flintstone hole to use to stop.
I hope everything works out.

It's only sheetmetal. This shows you "ain't skeert" to cut one up....

Blazerman - unfortunately the body lift had to be 4" - I will be moving the engine forward so I can get the body lift back down to 2" - but that will have to wait until I have more time for another project and $$.

I think your rig needs some 38's now. To go with that lift. Good job.

I was thinking the same thing about tires. I will have a total of 11" of lift now
 Will reduce that down to 9" when I move the engine forward. The 35"s will look small! Gotta save some money but at some point the 35" tires will go on the K5 and I will put something a bit bigger on this truck.

Body guy got the sheetmetal work done on the firewall. The inside is going to be hidden mostly by carpet so keep that in mind as you look at the pics. I'm pretty pleased with how this turned out. I think the gas pedal is going to work well still, I was a little worried before.
  Here is the inside passenger side  And outside passenger side
