comet is better. not too much. maybe a cup or so. coffee grounds mixed with cinder will do in a pinch. iron filings are also excellent.


for what is the good life if not doing things thoughtfully?

Hey guys he is probably right I worked with this bracket racer he would take his 100,000 mile 340 motor out every year and hone the cyl with a ball hone and put used rings back in the motor not the ones that came off the pistons because they were all broken and run most of the year consitent car 13.30's and when it would slow down he would take it out and replace the broken rings with other used rings. He also put cam bearings in with a long extension and hammer and it ran fine. I talked him into letting me put electronic ignition in his car in 1992. Dual points before that. When your on a budget that's the way it is. This guy was Heavy eleminator champ at a local pa track for many years in a row.

Will it run, sure. Will it be right, no. I understand all about budget and doing something cheap, but I still think it should be done right. Cast pistons are dirt cheap and a bore hone is not expensive. The whole process could likely be done for 150 bucks, with pistons. IMO, if you could not afford that, he should of just left the 250k shortblock assembled and went as is.....but I do realize that he was not asking for opinions, he only wanted to know how to get the carbon off. Seeing as that is the case, I am removing my from this discussion and should not have commented in the first place.

Monte,

I totally understand where you are coming from, but in this case, The customer only has about X amount of $$$ and our machine shop charges about 350 to bore the block, and pistons cost 150ish, and then you have to press the old ones off, and press the new ones on, all costs money the customer just didnt have.

We will be fine.

Thanks and If it was mine, and I had the cash it would get bored, Never said it was a perfect world.

Not disagreeing with you at all, but certain things just have to work on a budjet.

Yeah, it'd be better to replace the pistons, but... I'd try some aircraft paint stripper if I was going to try and reuse 'em.

Aircraft stripper is formulated to not eat aluminum. Seems to me I put some on some carbon and it chewed through it like Rosanne Barr on a chunk of roast beef

When I was a kid a local snowmobile racer would glass bead blast his pistons. Said it cleaned em up real nice but didnt effect the material.????? High school auto shop teacher would soak them in chem dip carb cleaner. (The shop had a 30 gallon drum) That was 20 years ago. I think the formula now is different and hard on metal?


Keep old mopars alive.

It's different but it's not that it's hard on metal...It's ineffective or carbon... EPA approved...
