Alright, i just recently bought a camaro from a guy in Ohio, its a 1969 camaro 327 engine with alot of HP big cam and tons of other stuff. My question is though, ive heard that i must run high octane fuel in a car such as mine being 11:1 pistones or els the cylinders will burn up???? if you can help it be great cuase i know high octane fuel isnt cheap and i just bought a car i gottta pay off
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.
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.

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.
