Dialing in


Recommended Posts

Looking for advice on where to start with my new build. 421 cub, drag port, .5 3 squish, 135 lb each side, 19 CC domes, thousand foot elevation.

6in K&N pods with outerwears, Lectron 38/40 HVs, Trinity stage 4 intakes, VF4 reeds.

R2 pipes.

Should I run 93 octane? Or add a booster? 

Where should I start with timing?

135? sounds low for that setup. you know the port timings? feel like 19cc should put you a little higher than that. 

thats pump gas range

you doing the compression test right with a quality tester?

race fuel is 165 170 range.

throttle wide open and kick until the needle stops.  I have a decent tester, you dont need a craftsman but something good and make sure the tester adapter that screws in is the SAME length as the spark plug or you will get a different reading
