Small update, as I ramp up to getting things crossed off the list.
I started getting the rocker shafts put in the motor, and I discovered that there was a slight burr from the chamfer process in the main bolt holes on the rocker mounts.
It was making it really tough to get some of the bolts through, some would not even go through.
I think it ended up being 5 of the individual rocker shafts that needed some "fine clearance work". It wasn't difficult or needed much work but the rocker shaft material is HARD, like pretty much as hard or harder than my files so it took a while.
I even read the instructions on torque specs, followed to a T, and they look pretty sexy when installed.
I carried on down the lost and installed the fancy Iriduim plugs for street and testing use. Gapped to 0.025", as these will be more for under 15psi and regular driving. Yes, they are TR7 heat range.
😉
I put the valve covers back on and installed plug wires. #8 is a giant pain in the butt. Its gonna get extra fuel and a couple degrees less timing I think.
I went to install the 160 degree thermostat, and discovered the installed water pump t-stat housing is the old style.... I was lucky though, my spare (from the 4.8) did have the post 2003 housing so its gonna work out.
I then discovered the Summit brand thermostat was about 0.05" larger in diameter than the stock one and would not fit. SO..... It was grinder and flap disc clearanced to fit and installed. (Stock 186f on the left)
Somehow I found the time to fix the BBQ, chiseling out rotting wet pellets and replacing a blow fuse.... Thank god, as I needed to meal prep.
