I have a chevy small block from a project I'm kind of giving up on, and I was thinking... just put it in my 240 with a dead engine. Does anyone have any information on a old school v8 swap? I know ls1 mounts are different than the other sbc's and I havent seen any info about doin an older swap, but if anyone has anything, lemme know.

I'm almost finished with mine. What information are you looking for?

It is a very involved swap. I'm running a first-gen 350 Chevy small block with a T5. You basically have to cut out half of the firewall because the bellhousing is larger than that on a KA/SR. Other than that you will basically have to pull the dash and rebuild the whole front end from scratch.

The mounts are different from the LS1 so no one makes a bolt in kit. The sbc mounts are a good 3-4" forward of the subframe so you have to fabricate some mounts.

I would not attempt this swap unless you are very good with fabrication.
