A fellow budget race here also...
Spent all winter piecing together a brand 'new' 360 for my circle burner.
Second race out a pushrod 'pushed' right through a rocker and caused catastrophic engine failure like I'd not experienced up to that time.
Blasted the piston, which came off the rod, which went clean through the side of the block. Coolant steam and oil smoked the whole track....VERY embarrassing to say the least ! But boy what a smoke show !! :shock: :shock: :oops: :oops: :oops: :oops:
:D :D :D :D :D :D :D :D :D :D

no kidden and OUT THEY WENT, kind of like a women they always get there way LOL. Im going to pull the motor this weekend and get it up to th machiest for an autopsy, I'll try to get some pics and put them on my race space for you all to see.

Got one head off it so far. UPDATE ON FINDINGS...
 
My car is at a friends house, he has been taking my car apart when he can little by little. Went over last night he had the right head ready to pull, we found a Brand new Expensive Comp lifter did i say they were brand new and expensive,on #8 ex broken ???? pulled the head and there is no sign of a vlave hitting a piston, the cyl look great and the tops of all the pistons look great, they was a little bit of black thick carbon on them I was running way fat. The head looks great no signs at all from anything gone wrong except for the #1 and the #2 rods sticking out the side of the block. So its still a mystery for all of us. This weekend im planning on pulling the other head and the motor and getting it up to the machinest for the autopsy.

WISH ME LUCK.... Ill keep everyone posted of the findings and hope some pictures.

here aree some pics of the findings, number 1 rod looks like a pretzel, and #6 was hydrolic ?? that is way wierd what ya think? [img][/img][img][/img][img][/img][img][/img] dam it cant figure it out how to add them, but if you would like they are on my racespace in my album.

I went and looked at those pics and to me it looks like the valves were hitting the piston in a couple of those pics.

TheYellaBrick 05-05-2010 01:28 PM

X2..at least on the only one pictured...really tough deal. Did you 'clay' the valve to piston clearance during the build ?

chpseat987 05-06-2010 11:47 AM

ya my machinest did, he said with the piston I had it barley met mininum clearance. I dont remember what that number is though.
