LS-7 crate engine

[goinforbroke]

Can anyone give me any info on this engine. I know of one which runs but needs rebuilt. I am interested in it but am unsure of what it's worth. I'd like to make an offer on it. It is complete and painted factory? black with a GM "off road use only" tag taped on valve cover, dated 1973. I have no numbers but can probably get them in the next few days.
Thank You

memory is a little fuzzy, but this is what I recall the
LS-7 was $5500 bucks back then into the 80's until gone, mint in the crate seem to bring the same money today, suppose to be a 12.5:1 motor making 550 hp just slap on a 800 double pumper holley and go.

depends on what that one looks like inside of it.

Adding up what it would take to build one today from available used high perf parts and you're north of $3K pretty quickly, especially considering all the little parts and tin. That's where I'd start for value and hope I could get it for that ballpark or less. After they discontinued the MK IV LS-6 and 7 crate engines, I bought one-over-the-counter in pieces and it wasn't cheap, even with the good-guy discount!

Good luck, BCD.

Thanks a lot for the info. I'm still unsure if he will part with it but, I don't want to pass up an opportunity like that.
