Nice drag times. Just a heads up. I ran an E-85 conversion in '09 here on the west coast when it was first available locally. Block lasted 1 1/2 years then windowed. I was running similar HP and around 400 WTQ on a mustang dyno. Pin actually ripped from the piston casting and threw rod into block. The instant torque provided by stock cams and turbo take there toll over time. It is a super fun setup. Torque is so underated......lol

That's a pretty decent amount of time for the block to last at the known torque limit for the block, how many miles were on it?
So far we had great luck with the stock block. Car was atleast 620whp during its 136 pass.
He's aware of the consequences, and believe me, I tried to talk him into retiring the stock block but he isn't ready yet.
Hopefully it doesn't make the decision by itself. Once hes ready, we are building him a new shortblock then we will really turn the boost up.

He has done very well with it. So he went to a 6266 shortly after converting to E-85? I think the stock style turbo turned up stresses the block more then the bigger turbos due to quicker torque delivery. At least that's from what I have seen across the boards and from personal experience. Also in both situations you turned down torque thresholds early.
Yes its safer to have a slower spooling turbo on the stock block when making a lot of power because the transition is much smoother and the power is shifted to the right more removing a lot of stress on the internals. Specifically the rods. The higher you rev, the more you stress the engine as well.
I don't know the full history on Morgan's car, I know we corrected a lot of issues though both mechanical and tuning related.
Whenever its a stock block I do what I can to soften the torque down low.
I want to achieve those numbers too. I'm getting my o2 dump n then going e85 in a few more weeks. I want to go foreword and don't plan on looking back. But would I need to upgrade my head bolts?
