This thread falls right in line with my project ... a 1986 Monte Carlo 100% stock bodied , 383 cid approx. 10.5 -1 and 3.42 gears for now ... will be going into the 2 series when I get serious. This will be a LSR ( Land Speed Racing ) car so accelertion in a 1/4 mile isnt my goal, ... right now I am looking at a 1 mile course and in the future a 3 mile and 5 mile.
I'm running flat tap pistons with alum heads. I havent picked out a cam yet but will be going with a hydraulic roller. I'm hoping to get away with 92 oct. and being able to use it as a daily driver .... even though it wont be. Its purpose will be for a cruise every so often and some LSR racing with the first event planned for June with the stock 305 for a baseline and then this fall to try it out with the 383 in it.
To be on topic I have always heard that for pump gas a BB needs to stay at 10.0-1 or below to work out.
