ohhh awesome! you came and saw me one night at a QR drift night?
either way, car looks great, goes really well too from the looks of the things hope to see it soon
As it sits.. owes me about $13k.
just picked all the bits up from the machine shop, it was in a pretty sorry state. This is the list of bits going back into the rebuild/freshen up and machine work done;
Rod and main bearings
4 Hypatec pistions
chrome rings
Cometic head gasket
ARP flywheel & rod bolts
ARP mains and head stud kits
resize rods
carck test rods and crank
match grind mains and big ends
radius oil holes
Tear drop oil holes
Hone block
ballancing machine pistion crown
Thats all for this bill, clutch and underdriven pulley sets are on the way. I hope to see then in the next few days.

Just thought I'd put some of the build tollerances ect that we have used building this engine. I have a few photos but not many, I'll try and get them up tonight but untill then... tech fodder.
Bore 83mm (bore 3.2685, pistion 3.2665)
stroke 77mm
swept cap 1665.6cc
1mm crushed commetic head gasket @ 60 ft/lbs
combined combustion chamber 39.4cc
Compression 10.56:1
bore/ cylinder clearances .0002
main bearing clearances .0015 @ 46 ft/lbs (journal size 1.8797)
big end clearances .0015 @ 36 ft/lbs (journal size 1.6441)
small ends .0011 (journal size .787)
both cams measure the same, Hks, 272 deg, .338 total lift 8.5mm.
lash on intake .0007 exhaust .0010
both the peak openings are set about the 110 deg mark at the moment. These will get fiddled with on the dyno later.

Very good! I am pleased to see thoroughness
Just FYI (although i can't speak for the HKS cams because i don't have their cam cards) most of the well-known-branded 272 cams suggest approximately ~105 degree centrelines for both intake and exhaust But i guess you'll find this out soon on the dyno.
Im sure we will head in that direction with the c-line setup. The guy who is helping with this thing had full TRD support as a privateer in the NZ rall champs in the mid 80's with his 86. We were having a look at his old enging build sheets over the last few weeks and decided to start at 110 inlet and 108 exhaust. He had some crazy 4A's with cams around 320 duration and 12mm lift, 225bhp... no wonder he won the NZ grp A rally champs twice.
5kg flywheel
boxes
numbered mains
main studs
ARP, the only way to roll
Note tear drop oil ducts on the mains
I heard that ARP flywheel bolts bottom out on 4age? Can't confirm for just another thing seen on the interwebz, haha.
"Not all commodore drivers are wankers, but all wankers drive commodores"
ARP dont list a kit for a 4age flywheel bolts anymore, could be the reason why. I will double check them to see before it gets fitted back in the car tonight.
