Re: 11:1 pistones what should i use?

the cylinders will burn up - well, not exactly What you'll get is detonation which is a premature ignition of the fuel caused by a 'hot spot' in the combustion chamber. That can cause lots of mean and nasty things that you don't want. Things like broken rings, broken pistons, burnt valves, etc... High compression engines like and need high octane fuel. Ignition timing can be fiddled with to help a tiny bit and I've had success with water injection on high compression engines. The water helps to cool the incoming air/fuel mixture and reduces the chances of detonation.

There's lots of other, more knowledgeable folks here who can give thier opinions.

If Engine Is Truly 11:1 Compression, You Will Need To Run Cam2 Gas For It To Run Property And Not Foul Plugs Every Day. I Personally Dont Care For Having To Do This. You Can Get A Lot Of Hp Without Having High Compression And The Need For $9/gallon Fuel.

Aluminum cylinder heads help out a lot too, but cost a pretty penny.

Re: 11:1 pistones what should i use?

well i just bought the car the guys got it septup to be a race car i mean im pretty sure i saved it from becoming a fully functional drag car. I dont have the money to pay for anything to add to it now, i only made 5k and bought it for 7k my parents bumped me the rest which i have to pay off. But i realized that running high octane fuel is exspensive and around here it runs for about $4 a gallon if im lucky gas prices will continue to go down. But id like to know about items i could get for my car to give it better gas mile's thank you for letting me know these things and replying to my post.

I've got an old 250ci inline 6 you could toss in there for better mpg. I'll even do a straight out trade for your fuel guzzling old 327.

Re: 11:1 pistones what should i use?

I am no expert, but high staic compression is only one element to the equation. Most all stock 302's that are 11:1 run fine on 93 octane because of the overlap of the cam. What I am saying is there is more to it than static compression. You have to look at the total engine specs. I bought this to try out.
