as a few of you know we melted a piston a few months ago in the race car.
well it also took out a sleeve.. that was replaced got everything back to the shop start to assemble it again. well it rubbed the thrust bearing... we had to get a new style thrust bearing because the old ones were discontuned in 2009 and we were always able to find back stock of them. well we thought the new ones must have been just a smidge thicker. so we sanded them down a little bit since we were trying to make a race. well after 3 or 4 times pulling crank in and out of the block we noticed the crank was cracked. wonderful! this isnt a standard off the shelf crank we are talking about. its a SBF crank that has cleveland mains and 2.100 rod bearings. on top of that it has a 4.125 stroke. lucky for us callies had 1 in stock... had it balanced per the rods and pistons we have in the motor. ordered new rods to be safe since we run aluminum rods in it... they need notched to clear the cam. got that done
get to the shop last night drop the crank in the block... now it rubs.
so block and crank are BACK at the machine shop...
racing this year has SUCKED!
