Dick. I've gave this A LOT of thought, and I say, (now, all I'm getting ready to propose is to ease tear down) any piston, any rings, angle mill, and polishing the combustion chamber is the ONLY thing allowed other then a valve job. Any stroke, but a 1" threaded hole in the side of the pan for inspection to keep ultra trick cranks out. Any size journal. I doubt the $1,300 rings are as advantageous without the pump. Stock type oil pump, no billet. Just ideas. All we'd have to do is P&G, check pan, put a good scope in exhaust port, and down intake, and BOOM. We're basically done. But now comes the argument comp guys will fool you easily. That's where the number 1 qualifier, top speed, winner, and or runner up, record breakers have to have head OK'd by BRODIX.

Piston tech could be the more expensive part but if fuel limited to VP-C-12 cant run too much compression...I would even support flat top piston for ease of inspection and low cost so no custom domes etc.

[randy wilson]

Flat top is fine with me, as long as it does not limit type, weight, etc. because of not having to pull the head.

[Dick Butler]

Anyone else opinion on flat piston versus Dome to get compression?versus low cost non custom dome manufacture.

Dick,

WHATEVER to keep the cost down. Is there possibly a spec piston? spec rod? I would prefer it if you could not do ANYTHING to the head. The more you allow, the more the cost.

The flat top part could be easily policed, but if you want a spec piston, and rod, you're talking about opening a can of worms. Every engine would have to be completely disassembled. I am against a spec rod, and piston. Not because I have some secret setup I'm trying to slide by, but because tech would be a nitemare. If I'm running a steel rod, and you're running the best, lightest rod MGP makes, they will run real close together. One has an advantage over the other in a totally different area. And ring packages. My 2 cents worth is, a .043 2 ring will run with a .043, .043, 3mm. Now the super thin rings might build 15 HP more then these two combos, but if that's what they have on you, you are real close to kicking their butts. Cut a .01 better light, and call it even. Also, without a vac pump, they ain't quite as attractive. Don't get me wrong, all the hitters will run them, but I'd love to go back to the shop, and say, "All we need is to spend an extra $1,300, and we're in. Beats the hell out of $10,000. The best, trickest piston is about $1,800. But a set that will run real close to them is an $900 set, so name your poison, and come on in. We've saved tons on heads, intakes, clutches, computers, etc.Back to the head. We found if you can't polish the chamber you risk detonation. If you can't mill, if you hurt the head, it's junk. Also, you have to remove the head to check both. Just letting you know the obstacles we faced, and addressed.

Anyone getting any feed back on the max lift of the cam? Here's my thoughts. Has to be big enough to allow performance, and RPM< but not so large to cause valve train problems. .700, or .750 is considered rather small today.
