A buddy ended up with extra parts, including R380 and stuff and a freshly rebuilt 4.0. We were going to build one good truck from one runner with a shit shell and a good shell with a shit 3.9. We may bail on it all due to time and grumpy neighbors. Anybody looking or know what I should expect to get for such combo?

Thanks.

I?ve seen prices in the $750-$1000 range for the 380. The 4.0 has maybe 100 miles on it since the rebuild.

Rebuilt 380s can be had for around $1300 +/- from Ashcroft. I've been trying to sell a rebuilt(never installed) 3.9 for $3k and had no offers.

Price points on engines seems to have dropped significantly for whatever reason. I recently saw a 4.6 being offered for $800 with all new gaskets/seals. That's a steal but where the prices seem to be today.
