1st post on Inliners so I figgured I better say hello & all that. So, Howdy!

Here's the deal: Have a '56 GMC 2-ton dump ( details here on the Stovebolt forum ), came with a running 270 & even drove around pretty well. Sounded like a sherman tank with a thrown track, but it moved! Stopping it?... Well thats a different topic.

Anyway, upon disassembly I discovered a couple issues with the 270, the poor bugger was only running off of 3 cylenders. Heavy corrosion on several valve seats, and major pitting on 3 of the cylenders, two of which look like they will need to be sleeved.
Still haven't gotten word from my machinist as to how deep the deepest pitting is, but I'm not holding out much faith that it's less than a .120 overbore seeing as it was already bored to .030 and I had to take a good amount off with a ridge reamer to get those out. I'm guessing it's around .050 over as is, so consequently I'm in the market for a workable 270 block. If it is salvageable I'm looking for folks that can point me in the direction of folks that offer pistons & rings up to .120 over.
I already have a set of .30 pistons if anyone has a block thats bored to that, will just have to chase down some rings & I'll be golden.

Another option I was looking at was a complete & preferably running 302, I'm trying to keep the configuration as near to stock as I can.

I'm in NW Washington between Bellingham & Seattle, I'm willing to make a reasonable road trip to pick up an engine, otherwise we can make arrangements for shipping one motor freight.

Gotta get off here & head to the shop, in the midst of pulling wheels, drums, & hubs for the brake rebuild process. Fun!!
I always appreciate any input &/or help I can get, thanks up front.

James.

Dear James;

Check with Buffalo Ent. There in Washington State & listed in our vendors list.

If Steve doesn't know he will know someone close that will.

Welcome aboard & good luck.

Larrowe & Sons in Sandy, OR (near Portland) tends to grab all the 302's they can around here, but he may have a 270 block that is in good shape for cheaper than a 302 block. I have a good running 302 but its not for sale.

if you interrested in a block i have a good 270 for sale ? in michgan

James, I will have a good rebuildable 270 available to part out for sale about middle of May. I'm working on getting it pulled out of the truck right now.
It's located in Vancouver, WA so it'd be sort of close to you. Let me know how things go and if your interested.

Thanks for all the help folks, always appreciated.

Slim_six, let me know what happens with that engine. Vancouver isn't all that far & if you're looking to offload the engine I'd definately be interested in driving down to have a look at it. What is it coming out of?
