The plan for my truck was to build a nice stroker so I could put a camper on and tow my Jeep behind it, but my old 390 died 2 weeks ago and I need something to get me by for right now.

Cool
Good luck with your build.
Take a whole shnitload of pics for all of us **** freaks.
Are both engines really 390s or are they 360s?
Checking the stroke of the "new" engine may give you a clue into the integrity of the build.

Don't hate too much on my Chevelle
, My mother bought it new in November 1969 and I just finished the restoration. I will pass it down to my son someday

I echo turbo's sentiment, it's already half tore down anyway, sure it's a little more work but the peace of mind you'll gain from doing so is worth it.

I picked up the engine today, I confirmed it is a 30 over 390 with D2TE-AA heads. What I don't know is compression or cam specs and the guy I bought it from had no clue either, he said the he just called the machine shop and asked for a stock 390 for his 1972 truck, then a week later this engine was delivered to his house. My guess is the compression is 8.0 to 8.5, the piston looks like a small dish with 4 valve reliefs.Do you guy's think a cam upgrade is worth my time?. I will be running headers and a performer intake I have sitting here
