Been doin a bit of fiddly shit.. Waiting on engine shop to finish boring and balancing.... Hopefully pick it all up tomorrow lunchtime and start grinding the block to clearance the crank.

Then put the bottom end together :D


Also got another set of shims put under the valvesprings so they meet the required specs for the cam. Had to make sure they wouldn't coil bind etc etc also. So should be all good for a 7500rpm limiter :) (normally could rev higher, but stroker changes things..)

Getting there... Should have motor ready to go into car by friday if everything goes to plan. Then its just all hook up and go.

Nothing fouled with the stroker, will just have to put washer under the oil squirters maybe..

Gapped the rings today to CP's specs and done a shitload of cleaning. Tomorrow should see the bottom end together fully and the head on :D

Nope. All cleared with over 40thou clearance. 86mm CP pistons and Eagle rods. Stock 4g64 crank unground. Might have to space out the oil squirters with a washer or two..

Maybe dint the sump also (longer stroke)

Used proper headstuds this time, not twincam ones. So had to cut the rocker cover a little. Blocked off a few holes that weren't used. Fixed some leaks that it used to have down near the oil pump. Decided to use mainly new bolts everywhere so had to go get them. Lots of small stuff really.

Should start tomorow arvo :)

Also, with the balance shaft block off kit, i wasn't happy with it. With the tension going on where the bottom shaft goes that little plug shitty thing they give you will just break/run off after a few big power runs.
So machined the balance shaft down to nothing so it ran through to the second bearing thingy.

If that makes sense... Lol
