sorry to hear that !! i have all my tickets and this friday made my 52nd pass on the 4.8 managed a 10.10 but still on 19 psi and this past sunday got called out by a 2010 corvette on nitrous got the win but im surprised how much beating it has taken... tomorrow i have a race against a supercharged mustang that has gone 9.8 so its time to take her into the 2xs psi eighter i manage the 9 or motor goes out !! this is an untouched 4.8 with 1 oil change since i put it in lol

 

So I've got the engine torn down and I was very surprised on what I found. Zero bent rods and all Pistons looks as good as new! I expected to see at least some butted rings or broken ring lands. I'm a little confused on why this happened though. Spun 4 rod bearing and a main bearing. Did I stretch the stock rod bolts to cause the bearings to spin? Can too much rpm cause this? I had just done a fresh oil change and checked oil level before making a pass. It was all up to par.

 

What crank pulley

 

Stock balancer

 

It means it's time for a bearing set, break in and go for 9s...

Detenatation usually takes the bearings out.

 

The crank is flexing. Look and see if there is fretting on the main caps were they mate to the block.

 

Impressive #'S...what is done suspension wise?
Thanks
Dom

 

Suspension is just basic leaf springs and caltracs. I'll try to take some time to farther inspect the block and crank. Been crazy busy at work this week so we can get all caught up and close the shop for next week.

 

What main and what rods spun?

 

Why would the crank be flexing? There are people making over 1000hp on stock cranks
