Hi. has been quite some time now, since I hassled you with my questionings. So, just wondering as I now finally reach the stage of assembling the bottom end, what the story is with 'alecular' bearings, for the mains? And then further to that, full groove, or half? Full groove worries me a little, as the bottom half of the bearing shell would offer less support area under heavy load/rpm? I have decided to up the ante a little, after discovering that I wont get this vehicle 'on the road' in Australia, due to heavy mods.... grrr. I am now going to run a Weiand Team G single plane manifold and lift the power range a little, mostly for drag racing now. I got the block decked to 10.180", zero decked it to the 1.52 pin height ROSS custom pistons, bored it 0.060" over, relieved it for the stroker (only a tiny bit for each rod bolt). Now sourcing the Crane Cams HR-240/365 hyd roller cam and wondering what to use for lifters. Any recommendations? Will any sort do, or are there better and worse? Fel-Pro#1027 gasket states it will compress to 0.039", so I feel that quench is going to be just fine. I just realised that it is over a year, since we chatted, so I hope you have been well.I was transferred to Tasmania, for work, about 3 weeks after your last message. COLD! Any feedback you might offer will be greatly appreciated. Cheers, Adrian.

Id suggest the CLEVITE H series as Ive always had good results with those... read the linked info below
And then further to that, full groove, or half?
upper bearing half,s , that seats in the block grooves are fine, but don,t use lower bearings that seat in the main caps

as a general rule you want to use the roller lifters made by the same manufacturer as the cam simply because if you use a different brand lifter , and have problems at any point, the cam warranty is always in question and unlikely to be honored, now in reality, it should make little or no difference , if quality parts are used

Heya again. Back into the project after some time away from it. Clevite H series Bearings I ordered from White Performance and Machine, I accidently clicked on .001" undersize instead of STD. Do I need to modify my order? What is the point of .001 under? tighter clearances? And also, any recommendations for oil pump brand and flow rate? Cheers and Happy New Year, Adrian. link to bearings I bought here>> http://www.ebay.com.au/itm/200907710197 ... 1439.l2649

I like ACL bearing, lots of people in my area do, apparently they are very strong and show very little to no wear at all vs the king's/clevite bearing.
I know bearing undersize sometime is used when you remove some metal from the crank, may be used to set bearing clearance too.

You could try contacting the ebay seller, he can be nice (and offer refund or exchange for the right size) or not.

having the correct bearing clearances are critical, to durability, generally you'll want no less than .0022-.0025 with .0025-.0028 preferred for most performance use. I prefer .0025-.0028 most of the time
Both rods & mains.

I don,t remember or you didn,t mention the oil pan capacity on that engine, BOTH MELLING and MILODON make a decent pump, I prefer MILODON HV standard pressure pumps
