To start the camaro was brought from a junk yard for$600 just for the body nothing on it or in it the rear end and all the steering components were found from different cars @ junkyards and e-bay. now for the engine it has a 350cid and a powerglide 2 speed transmission the motor has not been rebuit only the tranny.
the problem that i have is that i'm running on AV-GAS which is about 112 octane with a 13mL PER MINUTE burn and the car is not responding when i floor it. The street avenger 680cfm carburator is compatible for the use of aviation gasoline according to a representative from the jegs dept. now the car works like a charm as soon it pick up speed but not on the take off. please help on this minor detail.

Has the ignition system been upgraded to match? Sounds like your just dumping too much gas.

well the z-28 when initialy is started white smoke comes out the tail pipe but once it's hot it does not smoke only when it's started. how do i adjust the float and the jets.

White smoke is normally coolant, however on occasion, when the transmission vacuum modulator goes bad, the ATF is drwan intoo the intake at start up as well.

I think you need to adjust your base timing for that gas, which i'm not all that familiar with.
