dont foget to always assemble your engine in an environment that is 68.4 degrees celcius. that is the temprature of the engine build room at the factory.

hey man with the ring gap you mean 0.017 and 0.019 right not 0.0017 and 0.0019? :o

and also wouldnt you want the first ring to have more clearance (since more heat hits it) instead of having first ring a little less gap and 2nd ring more?

Ive got a question (like i always do) Whats tools did you need to have to assemble the short block? measuring wise. Im doing mine very soon (like in a few days) and i was curiouse what all i would need other than a ring compressor and a fealler gauge.

you also need a file to grind the rings down.. a hand one will take a long time, i set a dremel up sideways and used that, only put the ring end on there for 2 sec at a time and then go remeasure cause it eats it down quick :D

The idea behind a larger second ring gap is that combustion gas tends to get caught in between the top and second rings, and if it builds up enough, will cause the top ring to "flutter" and lose seal. So by opening up the second ring slightly, the small amounts of combustion gas just go into the crankcase rather than making the top ring lose seal. This is the same reason I will never use gapless second rings in a motor, and the same reason many pistons have a groove cut between the top and second rings.

It is a requirement. You have to set the ring end gaps correctly. Just take your time because if you nick the actual ring surface(that contacts the cylinder wall) then you have to get a new ring.

btw do you also lube the rod bolts with the arb lube or do you leave those dry for torqueing?

You have to use the lube. A dry torque is not an accurate torque.

what mm package should i be looking for? they have for example: .010 through .050 next mm package would be gauging from .060 through .100 Dont know if I explained that right or not but i think youll know what i mean. Basically i dont know which mm im looking for to measure what i need to for the assembly of the shortblock :oops:

Also one more question, what did you pay to have the block: Hot tanked, magnafluxed, bored, honed, and redecked. Im having mine done at a local shop and they quoted me $900+ for Rods/Crank ShotPeend, Block Tanked, Maged, Bored, Honed, Cleaned, and Balanced. I thought at first they included assembling it aswell.. but i called them and they said it didnt.. does $900 sound right for all that???
