6.5 Optimizer dimensions?

Hi all,

I'm hoping to find dimensions for the 6.5L Optimizer engine. I'm really after mechanical drawings or mounting specifications for this. I haven't been able to speak to the manufacturer AMGeneral due to time differences and they haven't replied to my emails.
Any chance one of you has dimensioned drawings of the engine or can point me at them?
Thanks in advance!

I haven't had any luck finding blueprints or dimensioned drawings for that either unfortunately. Google has provided lots of data about the engine itself but everything seems to assume you know what the mounting points will be and the size of the engine.

Hink, demensionally the same. Pretty much every component in the engines had improvements. Except same crappy (IMO) bearings and same excellent melling oil pump. Only thing idk is lifters,pushrods,valves,valve springs.

What I really need is a CAD model of it or similar so I can design around it but at a stretch blueprints/dimensions are sufficient.
Thanks for your help so far, searching for the generic 6.5 has brought up some useful leads.

Also maybe, the king daddy 6.5, better than the optimizer is the p400. It has a big lower girdle that spaces down between block and oil pan. And has the oil centrifuge on top which adds a tiny height iirc. If you are building something around a planned 6.5, maybe make room for a p400. We all pray in 5 more years there will be affordable military take outs hitting the market.

What are you building? We like projects!

I've just found on another forum that apparently all GM V8s, diesel and petrol have the same mounting layouts. So I've gotten a model of an LS3 off grab-cad which should provide sufficient accuracy for now. This one if anyone is interested; https://grabcad.com/library/ls3-engine-1

Regarding the project I can't say too much as it's a work job but it's a vehicle from scratch based around this engine.

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

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, laying the block upside down and putting the scanner upside down on top of the block for a 2d scan. 1/2400" = 0.0004".
Adjust the image to scale, stitch together images if multiple scans are required (just like an airphoto in GIS/mapping applications).
Draft on top of the scanned image to make a 2D CAD blueprint of the bottom end. Spot check in multiple places with calipers to make sure the scanner didn't distort the image in any way. Post to here and GrabCAD and whala!

Was the 6.2/6.5 designed in mils (1/1000"), fractional inches, or millimeters? What would I need to dimension the blueprint in? I am a civil technologist, not a mechanical tech. I'm not well versed in automotive design drafting but I have applicable software.
Would a drafted overlay on a 2D raster image be too shady to bet a CNC job on?

You would need to talk to the cnc shop and see what they required, inch or metric wouldn't matter to them.

The person writing the cnc program would be the person to talk to... I have a top quality cnc shop here that have done several items for me, the programing is just a small part of it.. and it's not cheap the first time...

I thought you were buying that crate motor??

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 seems legit but not 100% until I confirm in person it's the real deal and get it back across the border next month.
