Has anyone ever built a 377 Small Block?

[bucket]

That's the exact point of this conversation. Have a complete 350 with good internals and a bad block. Have access to a 400 block so I'm just running the idea through my mind. Negligible difference in prepping that one vs another 350 block.

Seems like you already have a good plan...

It kind of comes down to the fact that I (like a lot of us) have a ton of stuff laying around doing nothing.

Price pistons and bearing spacers . When pricing pistons verify you are getting pistons for the rods you intend going to use.

there were lots of road race cars from the late 70s-80s that ran 377s and they're nasty, high winding things. Lots of power when done right.

Just wanted to second this. They are really fun screamers. IIRC, a good lightweight set of pistons dialed up the fun factor. Nova, Camaro, even a Chevelle would love it. For a big truck … well it's still fun to spin a V8, right!?

Thanks everyone for confirming what I was thinking. Let me see what I can scrounge together and see what I can make out of it.

Going to start stripping this 350 down this evening and drop the heads off at the machine shop this week to see if they are salvageable.

Will update once I decide exactly what direction I end up going with this.

Heads off and ready for the machine shop. This was the engine that was in my Camaro when I bought it last spring.

If you build a 377 those heads will need steam holes,might have the machine shop drill them now. BTW I think your 350 block is salvageable. Which saves you lots of money,no bore,no new pistons,no bearing spacers. My .02

I hope that you are right. He told me to bring a bunch of pictures of the damage area around cylinder #8.

Drilling the steam holes will be easy peasy in the aluminum. I did it once in factory cast iron heads. Two holes were easy, the other 4 were work hardened and required a bit that a machinist friend gave me.

Or maybe it was the other way around... 4 holes were easy and 2 were hard. I dunno, it was nearly 20 years ago.

Yeah I wouldn't be concerned for myself,but lots of people prefer others do things. I never got it. I make mounts,brackets, build my own engines,etc,etc.where as lots of people buy everything.

No interest in a 406 and it wouldn't be specifically for a square. I build lots of stuff so would be just for the fun of building it.

Good luck
