You gotta play to pay, I am paying now.
Please tell me it will at LEAST have pistons in it? If you go rotary or electric, I dunno what I'm gonna do?!?

Class act to put up a post and discuss what happened.
And to remind customers thinking about a high 9 or low 10 second daily driver, that probably the odds are against you if you think it will be reliable for a couple of years.
I've been through one used shortblock I bought from a friend, 3 front diffs, 1 gearbox, 1 bell housing, one oil pump, one rear diff hollow shaft, and one driveshaft stuck to a t-case
Knock on wood that is it for a while

Well as many of you know my car blew the heater hose off the heater core at the BR Sport Compact Shootout. Luckily Trent wasn't burnt as the hot coolant came inside the car.
I wasn't sure what happened, could have been a head gasket, could have been a cracked block. I was really NOT looking forward to it being a cracked block but I was assuming the worse in my mind.
I built an entire new long block for the car as there have been some things I have been wanting to try.
Today Daniel and Steve finally got time to get my car in and swap the engines. I knew once the old one was out I'd find out what the problem was and move on from there.
This is probably the oddest failure I have seen. We did end up pressurizing the cooling system which popped the heater hose off. The short block looks like brand new, every bearing, piston, rod etc. like new. The combustion chambers are like new, the spark plugs are perfect there is one problem. The head gasket blew and actually torched the cylinder head OUTSIDE the SS o-ring. Even the valves are perfect. I have seen this happen before but it has always cut a valve, ruined the spark plug and then went from the combustion chamber out from there. Not the case in this instance.
It almost looks like the head was not flat and it just blew out from there, the damage appears to have started right where the o-ring ends meet.
I am relieved it's not a block. The head is an easy repair, weld it up and fix it, no problem.
It's more puzzling as the car had probably 100 plus dyno runs on it with this same tune in it, ran (5) 9.5's at 154+ mph a 9.42 at 155 mph and then just "poof".
I will have to check the injectors and such while it is apart just to make sure something didn't happen there.
This was all after the fuel rail stands broke off the car and the car was down about 40 whp, so maybe the problem is still something I hadn't found.
Anyway, you gotta pay to play.

David.
Do you believe this was in part caused by trying to brake the 9s barrier on pump gas?
Keep it up Dave
He actually did a 2JZ swap with NAAAAAAAS.
I don't think, at this time, that wanting a high 9 or low 10 second daily driver is a problem. I have quite a few of those types of builds out there and all are going very-very well. In my case, I am constantly pushing just a little harder and am no longer looking at those time but set my sights on low 9's, which I guess I have achieved. The other odd thing is the amount of dyno pulls and passes previous to this that worked well. I can see after viewing the logs the last few days on and off that I was definetely inching up on the "danger zone".
I do not feel that trying to go 9's on pump gas had any effect on the car, losing the fuel rail I feel was the start of the problems and lost power I had after that day. I had posted about that ordeal too. For those of you that missed it, on the last run of the day on pump gas the fuel rail stands broke off the intake and caused all the injectors to blow out of the head. After that the car was down on power. We pulled the head and had to fix all the valves and seats. Even after fixing the head the car was down on power, which I never did find. I don't think we checked to see if the head was flat when it was off. Looking back there is a good chance the head was warped and this could have attributed to the damage this time as the way the head was damaged is very odd, like the head was never sitting on the block.
I still intend to go 9's on pump gas, after everything is fixed it should be pretty easy to do actually.
The car will be running again today, I think.
