Exactly what I was gonna ask Pete!

I'll get the pad stamps tomorrow. A few years back I purchased two NOS LS7's out of the same boat dealership. All of these engines have been in the same spot for the last forty years. I remember seeing them when I was in high school. He's about ready to pack it in. I also purchased a complete (down to the date coded plug wires) 427. It came out of a station wagon that was wrecked with less than 10k miles on it. He used it to pull boats!

Are the marine engines reverse rotation?

[lowmile]

They are standard rotation, He's had them a while but he doesn't forget ANYTHING! They also come with vintage Mallory distributors, something about the GM version had an open spark which is a no no on a boat.

Very interesting, never knew about the marine 307. I don't have anything against any small block Chev. , but that was one engine that was ok for transportation and never considered by myself or buddies to &quot;hop up&quot;. The small bore, long stroke just did not make sense to race. Too restrictive breathing as the valves too close to cylinder walls, IMO. I wish I had one 307 now, that I passed on, BITD. It is the one out of the yellow 69 Camaro I have. The eng. code is DE if y'all ever come across one. I am willing to bet not too many were put in front of a 4 spd. like this one ? When I bought the car, I had been married for 3 years and while we were making our bills, we did not have a lot of extra cash. I had parted out a couple of cars earning the wife's approval to bring home cars I deemed to part out. The guy had the engine, 307, but he had it boiled out and bored .040. I thought, were would I find slugs for that? and why would I invest in such an engine? So, I bought the car and passed on the engine. Guy wanted $200 for each (car or 307). I ended up keeping the car, why, I don't know? My neighbor who was the same age and we pal'd around bought a nice 68 Nova 307. He was afraid to drive it because of the racket it made. Finally, wanting to help him, I had him open the hood and put it in gear and stand on the brake while giving it some gas. Found the problem. A broken L motor mount. That thing was ready to jump out of the engine bay, lol. Other than a couple of 72 307 pick ups, that is all my 307 experiences (Not true, had a couple of 70 Camaros with 307s but another time perhaps). Just thought guys would like a peak into the window of my life, so I share. Hope I did not Hi-jack or get too off topic?

BBBenny If a topic on a 307 high performance engine couldn't wonder off in a different direction, I don't know what would. LOL

No disrespect to my brother from another, bbbenny, I am bbbENTLEY, but ok, nonetheless, appreciate the compliment,lol.
Appreciate the humor in &quot;letting me down easy&quot; on the different direction, but as a Cincinnati,Oh. Hillbilly, &quot;marine&quot; was where your cousin went to serve our country, not talked in engine circles around these parts,lol.

I have a 1970 Slickcraft boat that has a chevy 307, motor is marked as a OMC...
Wondering if this motor would be the same as the high performance motor?

[lowmile]

Yes these came out of an OMC dealer. The pad stamp is VO7114CX
