Subject: Re: Season's over and time to rebuild. by rklessdriver on 2014/4/7 14:36:36 Just wanted to update on our progress with the engine - which has been a big hold up because of parts. I got the cyl heads from Chad Speier Thursday. Impressive work is all I can say. Some pleminary mock up work on the short block revelad the K1 Technology rods were hitting the camshaft... which is to be expected but this was some pretty serious contact and I didn't want to grind away a bunch of the rod bolt threads to clear the cam and that was what was going to have to happen if I countinued down this road and used the K1 Technology rods. I spent my new carb money on a set of Callies Ultra XD billet steel rods.... Almost $1400 worth. Made from a special 4330 Timkin Bearing steel and made in the USA. Very nice rods. Splayed bolts and an offset cap end for extra cam clearance. Good news is the Calllies Ultra XD's cleared the camshaft with .055 to spare. Bad news is it will be next season before I can afford to buy that C&S Aersol Billet carb I have been wanting. I also did a pleminary mock up on my rocker geometry and piston to valve clearance.... (1) I need more shims for the Jesel Rockers. You need really long valves to get .800 liftin a 23* SBC and the shims that came with the rockers were close but I still need to raise the stand height up to get the proper rocker geometry. (2) The exhaust valve hits the piston starting at 20* BTDC and all the way to 2* BTDC.... took .045 lash just to get it to clear barely. So we are going to fly cut .125 off the piston which should give me .080 piston to valve and with the actual valve lash lash and defletion it should open up to .100 or so. Once the pistons are fly cut we can balance the rotating assy and then assemble the short block. Things are getting there. Will |
