Well, it seems like a NOS L88 for $5K would be alot more bang for the buck in my opinion. Those don't look like a rect. port head(840) by looking at the front of them.

You're right....I just checked the casting number....it's a 454 block.
Another scam.

LM suffix is for a 69-427 390hp corvette which is correct.

That is a correct number for a 427 as well. Here's an excerpt from www.mortec.com

3963512....427.......69......2 or 4 bolt
3963512....454.......70-76...2 or 4 bolt

It is definitely a 427 but a 390 would be a oval port 2 bolt main. Go with the L88 for $1000 more.

I looked it up and saw it was an oval port, and I thought it was also a 2-bolt, but didn't want to say for fear of showing my ignorance!!!

He claims it's a 4-bolt, and I know some 4-bolts were made with this casting number, but I wasn't sure.

Like I said above, we are considering trying to find a 69-427 to put in the Yenko replica we have to get it as close to the original as possible....and this engine just isn't the one, right?
