I finally took some pics of the engine.

I have come to my senses and will run the cam I have as it is already broke in and is in great condition. The only things that will change is a tighter converter, stud mounted SS roller rockers and studs on the mains. I will replace the guides and check the valves and double check the push rod lengths as this may have been the reason for the guide failure.

Still not sure what was in the oil but here are some pics of the scratches in the cylinder walls. Also some of some painting I did.


Lookes like Daves car:D














Some pics of the main bearings with scratches

The painted stuff looks great!
The bare copper on the one side of the bearing isn't too pretty. The circular scratches, though bad are simply indicators that little nasty things were in there at some point. I'd rather have little rings in the bearings than in the crank. Noted the different colors of the exhaust valves. Interesting.
Wanna say hmmmmmm about the lines in your cyl honing. Burrs on the ring edges from the ring filing?

Good progress Kevin. If you change to main studs check the ease of the crank rotation as you torque the nuts down. Sometimes you have to have the main line honed with the studs because they can have a different clamping force on the mains than bolts, for lack of better terminology. If it turns easily when they are torqued all the way it should be fine. The scratches are more than I expected to see, but not really too excessive for racing it hard, as long as they will not catch a nail when scratched. The piston skirts probably caused it from a little rocking in the bore??

I planned on getting the block line bored honed with the main studs. Im sure a shop like Auto Truck Service can handle a job like that.

Unless you know someone:D

I can get you a number of a good friend that lives by Ben and Eric that can probably do the machine work, and he's a perfectionist! He did the machine work on Martin's last build I think, but now works for C&D Performance. PM me if your interested. I'm sure ATS would do a good job too and I'm glad to hear your going to have it done.

Going for all orange I see, surprised to see the intake orange, I'm sure it will look good.

Ya shoot me a PM with the #

The orange is for a change. I didnt like the black intake but didnt want to take off the paint so I keyed it and sprayed it orange. I will also paint the block orange. The water pump may go orange but the heads will stay aluminum.

My cylinder bores looked the same as yours. If you haven't already, you should take some sandpaper to the pistons if there are scratches on the sides of them that look the same as the bores....I used 600 tonight on mine. Machine shop said to use around 380 or something, but I already have 600 so I just took a little longer doing it.

As far as the different coloring on the valves, I've seen that before, in fact an old pair of heads in the garage look like that. Should just be an attribute of exhaust gases heating up the whole surround of the valve, keeping it hotter. Looks like you had a good A/F ratio...lots better than mine, I've been scraping black crap off the pistons and the heads.

Could tight ring gaps under hard pulls cause those scores?
My guess would be the junk he found in the oil. My ring gaps were a bit open(filed for nitrous app.), so that shouldn't have been the case.
