Sounds this fate may await all us "domers" unless another batch of domed pistons in various oversize options materializes...

Default resolution!

<---that's me now

ok the questions of what to do are answered.

For a brief summary of the goings on....:
-1975 to 1980 2f's came with domed pistons
-those match with 6103x heads that are open chambered
-you can't find domed pistons anymore..like anywhere, it seems.
-that means you're screwed unless you find a 6104x head which are used on later 2f's and you use the later flat top pistons that are still available, or you get really really lucky and find a set of domed pistons that someone had sitting around.

.....
so long story long, after 2 complete engines and lots of weirdness...
I brought all the newly machine parts back from Gunn using combinations of two motors, enough I thought to put back together a nice rebuilt fully machined 2f for my project from Gunn only to realize the pistons I was planning to use were the flat tops and not suitable for the 61030 head I had rebuilt.

I found a 61040 head from SteveH on the forum and dropped that off to be rebuilt and still haven't heard back from them on whether or not it can be rebuilt or not

in the meantine (over the past 4 months) Mike D's ebay skills are awesome....he found what amounts to a brand new set of domed 2f pistons RY6215-040 (1.00mm or .040" oversized) over two separate auctions...I've been watching for these and calling around for months, and he found them...

so for posterity's sake, and because I like pictures, here's some pics of all this domed and open chamber business that I wish had been pictured somewhere else when I started this....

man these look good!

now anyone still paying close attention will note that these are 1.00mm (.040") oversized domed ry6215-040 pistons and I've been blathering on and on about .030" or .75mm oversized bores and flat tops....

...hold please for a brief interlude to show another picture with questionable archival significance....

so yes, that means one more trip down to ol' Gunn to do ^ that again..but only the part about boring the block to .040 from .030 to use the shiny new slugs.

and just because I enjoy ridiculous-pictures-I-usually-find-on-the-internet-but-this-one-was-shot-from-my-driveway-yes-i-am-that-dumb....

I didn't do it this way again:

that ^ represents a marginally useful set of l3,4,and 5 vertebrae now.....no one ever accused me of above average intelligence. But hey, my wife got a new car and left me with this purple sienna I thought it would be better if, because its purple and its a mini-van, it at least smelled like oil ... I was wrong..but dang that thing is nice to drive with a busted up lower back, its like driving a sofa.

So that's my trip around the past 4 or so months ...



yes that's 3 cheers to Mike D for finding useful and nearly impossible to find pistons and for not letting me use my sweet dream purple mini-van this time to haul crap. if you have ever heard me mention the sienna during introductions at RS meetings and wondered who is this goofball and why is he talking about his van......
if you broke your back right after inheriting that bad-bad-man-mobile trying to prove its utilitarian and not just lame ... you'd mention it too. lol literally

Whilst it isn't quite like driving a sofa, what I like to do is toss a pallet into the bed of my FJ45 and then drop the engine onto the pallet with the cherry picker. The machine shop normally has a fork lift to take the palletized motor off the truck bed and put it back when they're done.

Seems to work okay and doesn't mess with my back...
