What what? I've never run the Gapless style rings before, so I'm gonna need some reason.... forcing the gap ring outward to completely seal the cylinder bore seems like it's good, in theory - what am I overlooking here?

Again never used em but from memory those that have found they were too hard a material and in a 7M block which is also quite hard they don't get to bed in.

Total Seal rings are hard...doesn't play well with the hard 7M block getting them to seat.

I come from a land down under
Personally I think they're too hard to run in a 7M and I wouldn't risk it on the chance that they might work!

I'm usually really happy to try new and unproven things but on these I'll stick with what I know works and I'd prefer to wear out rings before the block.
(I got the last new one in Australia and even that took some doing)

If the Arias don't work out, I'll be going Wiseco - I just talked to the guys over @ Summit, and it turns out that they are no longer carrying Arias pistons due to severe backorder problems with them.

I've got a price for the Wiseco/Eagle combo ($969 with rings) and a price from one supplier of $1110 for Arias/Eagle combo (with rings) - I'm awaiting one more person to get back to me on the Arias/Eagle combo.

I'm going to have to decide if the extra 22 gram savings is worth $141 difference in price :) Unless this other place (that I don't know if I can mention or not, but they contacted me via PM, so you know who you are ;)) can get closer to around $1000 or so, then I'll probably see about the Wiseco pistons over the Arias.

Alright, alright... *grumbles* I'll just make sure to be careful about my ring end gaps :)

Isn't all this decision making fun? :biglaugh:

Awaiting feedback on the prices, but it looks like my build is going to consist of:

Either Arias or Wiseco forged slugs, depending on price difference
Eagle ESP H beam forged rods
7M crankshaft, knife edged, lightened, polished, and all the other goodies ;)
Either Genuine Clevites, if I can find them, or NDC bearings all new throughout
ATI lightweight harmonic balancer
12lbs CroMo flywheel
Cometic 1.4mm MHG (to be determined based on the amount of material that is removed from the deck and head)

Everything will be zero balanced (a must, imho). I'll have the block bored WITH A TORQUE PLATE, and line honed through the mains.

99% sure I'll be having Bryan @ Maloof Racing doing the machine work. Mike recommended him in another thread, and his and I's conversations have been awesome thus far - I feel confident in the work he'll be doing.

Gonna be skipping over the Total Seal rings, and just go the old fashioned approach - file fitting my own rings ;)

spend some time in the oil system. Make sure your pump is within spec, gears are de-burred, clean, etc. Make sure your oil squirters function.

Seems like you have everything else taken care of.

Beautiful pic, man!

IJ, I'm going to have Bryan lighten the crank as much as possible.

bwest, I plan on replacing the springs in the oil squirters, and Bryan's assured me that he's got a load of tricks he does on the oil pumps!

Hey - anyone make a 7M crank scraper?

727 area code? NO EFFIN' WAY! They're down in Land O' Lakes, holy hell, I have family there.

Awesome, once my crank is finished in Georgia @ Bryan's shop, looks like me and the 'ol 7M shortblock will take a road trip to Lakes for a custom crank scraper :D Excellent find, Ian!
