you could go 305's but we did the 335cnc's first then used the heads when we upgraded to 540's.so far we got a 38 formula w/ arnesons to 110mph in alittle under a mile from a 30mph start.1 of my videos is on Arneson's web site.

yes air fuel ratio...just hoping can get the 02 to live in these lightnings, killed 3 in the last couple of years, put a bung in a tube this time, know it's not ideal, but normal location will not work...

sorry about the confusion(something to ponder later on ),,cruise I wouldn't go more than 12.8,,wot shoot for 11-11.3.does your procharger have an oil feed and return?friends set up gets the air pretty warm before the biggest intercooler they have,although 6lbs isn't to much.we run 8-9lbs.

I think we've all been led to believe roots blowers make tremendous heat and centrifugals simply blow icy cold air out of them.
If its a blow thru carb setup, I'd be very careful with leaning the afrs too much. The fuel distribution sucks on those setups. While you maybe will see 11.8 Afr average from the bank of the 4 cylinders, you very well can have a cylinder in the 12's ....port injection with a good intercooler, high 11's no problem at wot. .
