Nuclear re-construction...going back together!

Getting the shortblock back together after the unfortunate piston melting excursion.

Luckily the cylinder and deck weren't damaged...so pretty much a freshen up deal.

Honed it with a flex hone. What appeared to be some marking stuff at the same spot as piston damage on the #1 cylinder wall was a little aluminum from piston. Came right off.

Cleaned up the block with the pressure washer (hadn't used it in two years...took a little time to get it back in the game!).

Threw some paint on it before oil drips all over it. The brass freeze plugs have been in it since original assy. 17 years ago. I like them to look shiny..so I cover them with grease when painting. I'll then use some Scotchbrite to shine them up.

Spent last night gapping the Speed Pro Hellfire rings...that's always fun.

Laid the Callies crank back in place with new bearings. Old ones looked fine...but "while you're there" right?

Went over all the pistons to be sure all was good. Ring grooves are excellent...no issues. The Oliver rods are also perfect. Rod bearings looked perfect on disassembly also.

Thought I had some rod bearings in stock...turns out I didn't. Ordered them from O'Reilly's at 7:30 this morning and picked up a few hours later. "While you're there" right?

Got 7 pistons loaded back in place. Still waiting on the new one from Diamond. Hopefully soon.

Also need heads back from Brodix...again hopefully soon. And a set of Cometic head gaskets haven't got here yet. Everything else I think I have.

I've got a new timing belt to install on the Jesel belt drive. Other one looks fine but it's been there a long time too. Also new seals for it.

The cam was sent to Bullet to see about re-grinding it with a few more degrees of duration and re-arranging the timing events somewhat. I'm spinning the heck out of this thing (more than I thought I would) so might as well tweak it a little.

I've got a new set of roller lifters to install. The old ones have been there for 5+ years as well as took a 2500 mile road trip when it was N/A.

So, I'm going back together as quick as possible. I was scheduled to do a track rental last weekend, but of course had to bow out. But I will be back at it as soon as this thing is back together!

Re: Nuclear re-construction...going back together!

Here I am afraid to let a hair fall out of my head while I am near my block and you just toss it all together like nothing.


I need a bigger man card.

It helps that me and this engine have been together for 17 years.


It knows I'm going to spank it every chance I get...and I know where to look for the bruises!!

Re: Nuclear re-construction...going back together!

Much to admire about an engine which has been in service for 17 years.
A little tune up from time to time keeps it in the happy zone.

Re: Nuclear re-construction...going back together!

Hey Jim,
Impressive as always...Curious as to the valve springs you use, and, being a 'throw away item' how long do you keep them in ?

Re: Nuclear re-construction...going back together!

The ones currently on these heads are what came from Brodix years ago. I believe they are Manley NexTek's. Knock on wood...I've never had one break over the years. My N/A cam was very, very easy on springs and even after years of use and they had lost tension down to 400 psi OPEN they were still revving 7500 RPM with no issues.

I didn't test these before I sent them in to Brodix...but I'll know how they ck out as they freshen the heads.

But overall...it's actually not something I've ever worried about. I ck them occasionally and replace them every few years maybe. Let's see...in 17 years...my old heads came with a set....and I think I changed them twice. And then there is this set that has 5 years of running on them if that gives you an idea.
