Ignition: 8mm HT leads with HEI for healthier spark...this enables gaps around the 32/1000. Colder plugs, yep...on a V8 with duel plane or std manifolds 4 cnr plugs up one heat value, down at least 1 step from stock. Carb etc...choose for the size of engine and RPM range On IMPCO mount mixer facing ...

Check to make sure the carb base is not warped, put it on a true flat surface or use a straight edge across it.
This is the normal method...
Placing on a sheet of glass and a little sand paper, the give a bit of a rub. the less experienced person can then 'see' the high and low spots.

Yep LPG is very sensitive to the quality of the spark I had some success regapping plugs a tad closer Follow the HT circuit.... From coil to dizzy cap...to rotor.. THEN it jumps to the terminal up the HT lead to spark plug THEN jumps the gap The total gap in the cap and the plug is what is actually ...

My goal is to have a 461 CID engine producing 600 horsepower and 600 pound foot of torque. It has been done with other engines running N/A pump gas, what I want to know is: can it be done on LPG? These results are achieved with the engine built to the required specs of the fuel used...using a diffe...

LPG is sensitive to the spark....good HT leads, spark plugs etc are a must. I use Top Gun SSteel spiral wound HY leads...and NGK plugs. After some yrs of evperimentation I run plugs in a range as cold as possible.... A set of plugs lasts me 2 or 3 yrs, get a single, miss I just replace with full set...
