Hi allmotor, im building a sohc mini me for a friend and I need some clearances and specs for max power and reliability. Here is the setup:

-Y7 block
-Y7 crank cut .010" (I was opossed to this but funds are lacking)
-New Topline bearings (only ones in bigger size)
-PM6 pistons
-PM6 rods with ARP rod bolts (gonna have them pressed tomorrow, didnt know about the resizing until todayf)
-Ported and shimmed Y7 Oil pump
-P&P Z6 head milled 0.020" Total compression should be 10.8 more or less
-ZEX 59300 camshaft
-crower cam gear
-New rings
-Z6 IM P&P
-60mm TB
-header, intake and exhaust 2.25 (should I go to 2.5? it will be crush bent)
-eg6ajk chip with 8500rpm redline (I have 3 to try them out) <== very cool guy


Ok, now for the info I need:
-What are good bearing clearaces for both main and rod? (0.015")
-What is the best ring gap for allmotor and good oil control?
-What should valve clearances be for breaking-in the ZEX cam and then for runing it for max power?
-What should my cam timing be at for it to be at 0 degrees? Milling means I have to advance it 2deg and the diference between block and head???


Thanks in advance for all the help and tips on the build, its gonna be my first all out build so wish me luck . Im expecting 140whp with some tuning, is that allright? Later on new valvesprings will be ordered and I maybe some more mill on the head.

CKP

what headgasket are you using? y8 - 3 or 2 layer?

advance the cam timing 1 degree for every 0.012" off the head and HG thickness. i assume the y7 block has the same deck height as anyother d16 - 212mm.

 

Ill be using the standard 3 layer.

but is there a difference between the y7 block and the z6 block? When I did a minime me on a d16a6 I had to retard cam timing 5 degrees, is ti the same with the y7 with z6 head?
