You'll need bore, pin size & height plus retention method (press/circlip etc), skirt length, ring land heights.
Ideally find a rod/piston combo thats overall the same but a longer rod/shorter piston combo that also allows the crank to be negative offset ground with only 2-3mm loss of swept stroke (increases RPM, reduces bore/skirt side loading, reduces overall loads) and gains the swept volume loss back in oversize boring.
At least the 2nd hand block is going to a good home. Martin has claimed it, to convert to a coffee table for his shed housed shrine to all things P38!! At least I hope its in the shed and not the lounge. Glad it'll live on, albeit not as LR intended it to function.
The only thing I'd request in return, is a beer from said coffee table whilst sat on the P38 lounge seats (are they functioning electric seats?). Luxury. Even when you're not in your road going P38, you can still feel enveloped and cosseted by it - wonderful.
Managed to get a set of 4.6L pistons out of the UK for reasonable money - 2nd hand of course out of a 2001 model.
So I'll end up with a spare sets as follows: 4.6L LC pistons (32cc bowl/dish) & 4.0L HC (14cc dish/bowl) pistons.
I'll post them for sale eventually, but if anybody is interested, make me an offer. There's suffient piston pins to go with them, but you'll may prefer to source new ones.
So the pistons I brought back from the UK have been bowled out to 25cc to allow for 0.005" deck height at TDC. The new gudgeon pins arrived from summit racing. Calcs show the CR will be 10.2.
The engine is pretty much assembled. The top hat liners are in. The crank tunnel was bored (see above) and bushes were made for 2 of the camshaft bearings. I've bought new oil pump internals. And Orger have sourced a custom vernier (rollmaster) timing set to go with the "mild road" Kent cam.
Next is assembly of the heads to check needed pushrod length.
Then I'll get them my currently installed flywheel to check balancing.
I'm mating my currently installed inlet manifold, which may need tinkering with given the machining that's been done.
Looking forward to getting the darn thing in.
I have just read through your posts and admire your tenacity. Good luck on your quest.:D
Tenacity. Insane might be more appropriate. Just hoping the end result is worth it.

Yep - looks like I'll be getting some royalties!!
I believe this is my engine that is featured. Looks good hey. Even more excited now.
You are going to finish up with one brilliant engine (shiny clean brilliant too). $$$?Quote:

Standard LC engines can be pretty sluggish at times, depending on what you're towing and what's on board. As I'm sure we can all attest to.
I guess I'm paying for peace of mind and bullet proofing. Looks like I'll be taking this one to the grave. I'm 45 by the way.
I wonder how soon it'll be before an oil leak develops. Straight out of the box? Are we taking bets?
