What's up? Haven't completed the billet FE yet right?
More details please....  |
I just wanted to see if people actually read this stuff. Yes, I did want to clean my pistons and had searched for good answers. Nothing I've tried has worked and I'm not willing to scrape, blast or otherwise risk destroying the pistons if I know some chemical will soften the stuff and help remove it.
As for the 302 block, Sandwich and I designed and programmed the billet FE. It makes ungodly power at speeds highly forbidden by local law enforcers. And, it looks VERY cool. I lost my stroked 302 out at Miller Motorsports Park last April during the last Kirkham track day. So, what with my numchuck skills, my bowstaff skills and my solid modeling skills, I figured who better to design engine number 2! It's being designed to be light weight, stiff as hell and have a bullet proof bottom end. I'm about 98% done and hope to get the design off to Sandwich for him to work his magic turning the model into code and code into a billet 302. We'll post pictures soon.

Don't worry about blasting the pistons.....

Thanks for bringing this out in the daylight-sounds great. Yes, some of us do read stuff...
Dunno how you project those power figures (2+HP / CI) just by block stiffness at 302 cubic inches without 4 valve heads. But if you can get it to 9000+ (on pushrods), I guess it's possible.
Watching your progress eagerly.

Two piece heads....with a big "O" ring.....the spring pressures would help hold it together??? Both ports cut in to lower section.

Chris, You're such an idiot! Bowstaff skills? I thought the only skills you had were picking your nose!
I wonder if oven cleaner would take the carbon off.
On a side note, Congratulations to Chris and his wife, this Friday, they will be having a new baby girl enter there lives.

working in a small engine shop the bench grinder had a wire wheel on one side and was used quite a bit to take carbon off the aluminum heads, valves and whatever else. got quite a bit of use. wouldn't of course work for gas ports but 8 pistons=about 10 min.

Still to this day use mine for cleaning pistons and other engine parts,fast and effective........

Glass beading under low pressure works well. So does the Berrymans Chemical dip which was/is used on Carburetors. It is getting a little difficult to find because it is caustic.

Had a nice "final" design review of the 302 with Thomas, Chris, and Sandwich a couple of days ago. Just bought a new CNC mill--it's HUGE...

Then we want to make some billet heads! Anybody got any good ideas how to machine a good water jacket around the combustion chamber?

As others have said (and is obvious), you'll need to make a two piece head design, IMHO. I would think maching the bottom half just below the spring seat shelf and leaving bosses around the perimeter of the bottom half for small cap screws to connect the two halves and seal the head along with O-rings if necessary. With your machining skills, I would think the two halves would fit together so seamlessly, that there would be an almost invisible line at the junction.
It's all just aluminum, programming, and time. So, what else have you got to do? It isn't like you're busy is it?
Looking forward to some more innovative work from the KMS shop....
