man im hopin mine doesnt look like that when it comes time to figure out whats wrong with my mess. im hoping my drive pressure cause the head gasket to blow.

your mess doesnt look as simple as a head gasket???? lol

 

Soggy, it looks like you floated the valves (see valve footprints in no2 & 3 pistons, . . . and #4, . . . ).

Correct?

 

I don't know, I think a little JB weld and an angle grinder will make it as good as new.

I think you are right BC, obviously there was valve-piston contact, I think it was partly from valve float and partly because my camshaft program was just a little too big, allowing it to contact a high rpm. Add a scarred piston crown, high temps, and the fact that that I continued to drive for about 30 miles after I knew something was wrong, and you get a melted and smashed piston (number 5), a wrecked cylinder head, cracked cylinder (also number 5), and scoring on several other cylinder walls.

Fletcher is taking very good care of me, the engine is at his shop getting rebuilt at an unbelievable (in a good way) price. He is balancing the rotating assembly, putting his biggest cam w/ a retainer in, O-ringing the new head, putting his big dual valve springs in, taking care of the freeze plugs, and a bunch more stuff that I can't remember at the moment. I'm hoping to have a set of twins on it before it goes back in also. I can't wait to get it back, hoping to have it back running in time for the July 24 NHRDA event in Portland.

 

I would tend to agree with that... Still runnin stock springs with that much boost?

Gotta remember with a boosted engine its not only rpms you have to worry about with valve float...

That being said... Thats nasty! Good luck...

 

I had Cummins 60lb springs, both intake and exhaust. Boost was a touch over 50 max. I would recommend Not buying the Cummins 60lbers, I'm not saying they were the cause of this destruction, just saying I have learned there are much better options out there.

 

That was with the diesel pro's cam? Do you have the specs for it? Did u check valve to piston clearance?

Thats almost makes me sick! Sorry that happened to ya, but sounds like you'll have it back and running even better.

 

I dunno . . .. I'm running Cummins 60#'ers and have had up 70psig boost against them (35/3B) with a stock cam. Slipping in a Hamilton 181/210 dropped the boost to less than 60psig. With that 3B now blowing into a 65/62/14 increased the flow volume without raising the boost to speak of. Had that up to 4300rpms (or so) with no known issues.

But yes, there are better options available there.

Yours may be related to the valve-train geometry.

On that head, have the valve seats ever been ground? (Recessing them in the head) If so, was the installed height of the springs addressed (shimmed)?

 

Yes, that was with diesel pros Killer B, I would definitely recommend it, spooled the SB66 like mad, I don't know the specs and I didn't measure the clearance as it was a drop in cam. I checked the clearance by turning the engine over after each valve was set. It was obviously only a high rpm hit, I ran if for 2-3 months, then I dynoed it and shortly after that bad things happened. I was actually happy in a way to see the mess when we pulled the head. What better opportunity to build it stronger and better??

 

I have nothing against the Cummins springs, tons of guys run them with no troubles. I'm just saying there are a lot better aftermarket options. They have not been ground since I got it, don't have any way of knowing what was done before that, but there were no shims under the stock springs.

Did you get the transmission back together yet? We want to see a 12

 

she aint pretty but shes mine!!!

 

I'll post a pic on my CTD later.

Here's a sneak peak: We had some good times with the VE, but came accross a good deal on a '96. Have no fears we put the complete '89 motor in the '96. Will try and get pics of that too, one of these days. The plan is to build up the auto in the 2nd gen and use the VE's torque to make it go fast. Boosted launches are fun, but the tranny won't stand too many more of them.

Sorry for the poor quality, will have better ones when I get around to it.

 

gigidy goo


you got that all decked out, the soft plug thing in back, nice polished valve covers and intake plate, P pump which prolly has a custom or aftermarket fuel plate and huge delivery valves and timing, and it looks like a 3 piece manifold with an hx35 or 40?? just a guess lol

 

Beautiful engine Captain, that one is going in the puller? Care to share any specs on it?
