My 97 SJ Motor build 85mm Flat Top*Done and Runs!!!*

[BROSS]

The companys name is HM Elliot Coatings, in Mooresville, not shure on the web site. He was Rusty Wallace's Head engine builder in the 80's and early 90's, he's been coating since 94 and does all my dads pistons and bearings everywhere he worked. He came highly recomended.

ahh,, i knew the skirt coating help with the filling of imperfections making it tighter tolerance.. had not idea the dome coating repelled heat. Do they have a website? i'l like to read up on it.

People have been ceramic coating the piston tops for years; it creates a good thermal barrier and helps with keeping the rings cooler.

Thanks for the link, they explain it a little better than I can.

The cylinders are in my hands and WOW what a piece of work, Tim your the man, fast shipping, 2 month turn around, not to bad. Now just waiting on the girdle kit from blowsion, should be here next week.

As luck would have it, I assembled the motor, purrrdy at that, as I was checking squish I found a bent rod, could not believe it. So now the motor has to come down and a new crank is on the way. I'll get a pic of the engine before it comes down. thats a real :nutkick:

wow that sucks, at least you found it now than with the new goodies inside. must not be bent bad, 1/10mm???

is the bent rod going to effect your flywheel balancing act?

The squish was off by .008 from front to back, you can see the pistons to one side of the bore, still went together ok, I'll get a pic of it. The front cylinder had .035" squish, even. No to the balancing, the crank end I cut off a bad crank and my dad trued it before starting.

It's probably a good thing you found the crank problem now rather than later.

Can you post some pictures of the TJ cylinder porting?

 

[tom21]

I'm not shure how TJ would feel about pictures of his work on the net. Not that its a big secret but thats what people pay him for. Not trying to be a d**k at all.

Never mind they're a bunch of porting pictures on the Judge Motorsports web site. :grumble:

When some advertizes porting it helps to see some of their work because you can usually judge how much effort and time was spent.

LOL!!! Nice try...

 

[BROSS]

Here she is before the tear down:261:

No pic of the bent rod.

Well I got a new crank from Riva, Trued and welded, not cheap. I got the motor together and checked squish, its a little tight at .035". TJ said I might be able to run it but dont over rev it!! I think I may machine the domes to get .039" to .040". I'm waiting on the hood and battery box anyways. I have a hood if I need to borrow one to ride, still looking at a week or two. Pics to follow.

 

[DAG]

Is this the center battery mount?
If that thing turns out good, think he'll make me one.

 

[BROSS]

Not shure on more yet, I think its gonna be awsome. He has everything done but the hooks for the straps, I'll see it this week.

 

[Philip Clemmons]

Quite impressive................I need to come ride that thing when its done.....:Banane01:

 

[BROSS]

Update time, just waiting on the battery box and fuel pump bracket, oh yea the hood is still at the painters...
