Well after returning the last subwoofer set up. I found another box more in line with what the wife wanted

Filled with a cheap Skar 12 powers by there 500/1 amp. Nothing earth shattering and just enough to make the wife happy.

Damn, that’s some weight loss..! I’m sitting at just under 5800. [emoji15]

Well the 2wd PPVs are right around 5300, so I put her on a healthy diet. There is another easy 50# I could drop. By at 5000# I'm happy.....still full interior, ac and comfy daily driver.

If I go with an aluminum block motor I can drop another 120# there.

machine shop called today!
looks like they bumped me to the front of the line.

got my stuff back, but i have a little concern.
first they should need to add weight to the crank to counter the extra weight of the pistons right?
It looks like they removed weight...

I took my wife's food scale and measured the pistons with rings, wrist pin, etc.
then took the oem with the same stuff.
sure enough, the new stiff is heavier...

:hmmm2:

Next the crank work, googling around it looks like the stock specs are
Main: 2.559
Measured: 2.556

Rod: 2.100 in.
Measured: 2.097

So i'm looking at some undersized bearings to make up for the difference.

found some nice .001 undersized for the mains
gets me closer...

then for the rods, i found some .001 and .002 undersized.
but they appear to come in singles, so i figure i might as well order one of each to see where it lands then order the rest.

Took a little road trip yesterday to haul home some goodies.

First was an Atrend ported enclosure for a Kicker L5/L7. These things are around $175 new and that's probably before shipping. A guy ordered it by mistake and just stashed it in his spare closet (return shipping wasn't worth it) and forgot about it. He was moving out of state and looking to offload it ASAP. I got it for $50:

I've had a 10" Alpine Type R for years and never taken it out of its original box. I want to build a center console box for it that'll go between the rear captains seats. Considering the labor and cost of materials, $50 for this one as a temporary solution is much more than worth it. It's size is plenty close enough to Alpine's recommendations to work with. I'll notch the four sides of the hole so the sub can be recessed and mounted to a baffle I'll mount on the inside, made of two pieces of 3/4" MDF:

I continued on to Lake Charles, two hours west of home, to meet up with some peeps selling a set of Pirelli Scorpion tires taken off a new F-150 in favor of off-road tires. They have just under 3,000 miles on them. Being 275/45-22, they're kind of an oddball size but they're exactly what I wanted for my "new" 22s and planned further drop. Scored 'em for $380:

The 'ol Hoe did good, averaging 22MPG cruising at 75 there and back. I say "averaging" because it bounced between 19 and 24 depending on the slight angles in the road, but stayed at 22 for the majority of the time:
