I would make plans in case anyone else needs them. I could also draft up parts of the crate motor. If I take the time to draft it I want it to be useful for the CNC specialist or for other uses. Could you ask them for me or pass along their contact info? I PayPal'd a 50% deposit, the deal...

Checked around, even with U of A and U of C... Everyone who does 3D scanning up here is for the geomatics or land survey industry, no mechanical or small part scanners. Nobody in Alberta that I could find. Was thinking of buying/borrowing a 2400DPI flatbed laser scanner, detaching the lid...

If anyone lives north of Houston, I'm hoping they could take a trip to Conroe/Woodlands area to inspect a crate motor I may buy. So I don't pay freight to Canada and realize it's not what the seller said it was. Would pay for the gas & time round trip. Thanks.

Yup, AAA grade Alberta beef right here. Born and raised. Recently moved to GP from Edmonton. Fitting how Texas has a Grande Prairie, isn't Texas 'Murica's 'Berta!? Good luck with your build as well! The PMD heatsync makes a world of difference, I found the more expensive FSD's hold up a lot...

Great thanks! Ok we'll play it by ear. In case someone else is coming closer to montana or is making the trip sooner.

The Woodlands, ~30Km north of Houston. You would be going from Texas back to Utah?

*correction - From TEXAS!

I may have an optimizer block to sell next month. It is being honed and inspected for cracks right now including crank deflection. The heads passed inspection and pressure testing. No paint. Proof of inspection will be provided. Can complete the rebuild and sell the long block for $4200 USD...

I'm curious if anyone here could hitchhike a 6.5 crate motor from Arizona to Montana or Idaho. If someone would be making the trip anyway in the next couple months. Looking to cost share on a commute you would be making anyway.

@Will L. I ran a file over the rocker and the washer, the washer seemed to get more scarring so I think the washer is softer. The rivets are just black/ductile iron and I think the rockers are steel alloy. As for drilling out the rivet pin, I'd be worried about unintentionally taking metal away...

Welcome! Has the fuel solenoid driver been relocated from the ip to a heatsync? That's another common fail point. They overheat easy

The stock 6.5 rocker is held in place by a nylon button. I had one break on me, now I'm replacing the piston rings in cylinder 6 because of it. No way I'm putting nylon in again. I could have gone with expensive HS roller rockers, or the bolt method, but I thought I'd try something similar to...

BUMP! Has anyone dimensioned the GM 506 block yet? I want to start drafting up a full girdle and block spacers for CNC

The girdle I have was already in the engine when I got it, but I found the install PDF here: https://www.dieselservices.com/images/Stud_Girdle.pdf Hope this helps

I got my info from source 2 before joining the forum, so I'm glad I posted my initial plans here and got feedback. I don't plan on using stock or marine pistons if I get p400 rods now that I know the pistons are dramatically different too. My work order is on hold with the machine shop while I...

I'll post a DIY topic, but I bought 1/4" stainless steel pop rivets, they're fat and just barely fit in the hole of the pipe the rockers slide onto. The hole and the rivet are exactly 1/4". I measured the plastic button, the inside dimensions of the rocker, and special ordered some thick iron...

Ok good, that's that I was worried about. I agree TS, definitely wouldn't want to mix and match with a rotating assembly. And if the metallurgy changed it's for good reason.

I'm requesting quotes for the p400 crank rods rod bearings and pistons. I have gotten some interesting comments from suppliers about the P400 & GM pistons oil squirters and rods. Source 1 says you cannot use P400 pistons with GM rods, or P400 rods with GM pistons, and the rod bearings are...

P400 heads, cranks & rods, rod bearings, and standard size pistons are all still available. For now. If one already had a 2001+ optimizer 6500 longblock, could they refit it to be on par with a p400? From what I know, you would need: A bedplate, custom CNC'd from scratch to fit a vanilla...
