Nice work. Really smart process using the sacrificial pieces to make your desired bend!
What kind of motor is that? Would there be any issues getting it in or out with the forward firewall in position?

Motor is a 6.2L LS3 with an ASA cam, should have plenty of go-power when you tap the skinny pedal. Good call, with the relatively large T56 Magnum it's gonna be challenging to get the motor/tranny combo in and out easily. I'm not going to permanently attach the firewall for a while yet, hopefully after the last time the engine goes in. I actually installed the tranny from the bottom and mated it to the engine with no flywheel or clutch at the moment. I may just keep doing that since it worked pretty well working by myself but we'll see.

jeepurz, I suspect your 6061 had a T-6 heat treatment and that stuff just does not want to bend 90-deg even as thin as .050". If you use a large enough radius (like you did) it works OK but is tough to bend. When I need to increase the radius I use pre-bent strips to fit over the fingers that way I'm still only bending one sheet. Since I have a pan brake with individual fingers the strip also improves the bend quality. There are bending radius charts you can refer to. Or if you don't need the T-6 strength you can pick up 6061 in T-4 or O (annealed) treatment and it's much easier to bend and work with in general. Also much less expensive. For future panels consider 3003-O temper -- it's even easier to work with, has better corrosion resistance properties, and way less expensive that 6061 T-6. 6061 T-6 is heat treated structural aluminum with much higher tensile strength making it hard to work with when forming shapes. I enjoy seeing guys take the uncharted path and putting their personal touch on their builds. Looks like you have fabrication experience and not afraid to modify things to suit your needs. Good work!

Nice work! That extra room will be nice to work with. Mine is crammed with duct hose now, even though I made up a small heater box mounted to the engine side of the firewall, and the only protrusions inside are three 1 3/4" snouts to attaché hoses to. If you're installing wipers later, I suspect the tube and wheel boxes will now be behind the firewall between the firewall and dash, keep that in mind for clearance. Remember that you'll need access to the windshield frame holes that are now behind the dash on passengers side, although it might be easier than the standard setup.
