Oh yea :peace: was stoked to see it had the 7.4 on the listing
...big alternator you say ? What's the deets with that
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.

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.
