Do NOT change out those wheels. Those are '90s retro-cool.

It's a CS144D. Probably 140 amp maybe 125 amp, vs the CS130 105 amp most trucks got. You should grab a pic of the RPO sticker in the glovebox. If it's original, there should be a code starting with "KG" and a number that would tell you for sure which amperage.

I dont mind them. They are period correct, Centerline Hellcat wheels I believe. The center caps are a bit chonky tho. Might run without them

Sweet! What a great looking truck! I'll bet you had a feeling of accomplishment!

Welcome to the mother lode of all things GMT400!

If i were to spec my perfect truck, it would be very similar to this. Very nice!

Love the car phone, i assume the antenna on the hood/fender is for the phone? Do you plan on keeping it?

Those alternators are uncommon on GMT400s, i have one on my Tahoe. I like them a lot.

From a fellow 454 powered ECSB owner, welcome to the forum!
As a quick tangent regarding alternators; I'd look into swapping to an AD244 style once that CS144 gives any trouble. I did the swap and I love it! It's easier on the 7.4 trucks since the belt length stays the same, you just have to remove the rear bracket and the big alternator drops right in; you'd have to swap pigtails as well but that's an easy job.

Interesting, appreciate the knowledge man
