Re: One of ? L89 Nova for sale at Russo and Steele
[ QUOTE ]
11.0 to 1 with 842's and 9.5 with the 074's....and a possibility of the Domes on the Stock L-78 Pistons hitting the Combustion Chamber in the Exhaust valve area....the Closed Chamber had a straight sidewall next to the exhaust valve which shrouded it......the open has a much larger chamber, but to unshroud the valve, they open up that area, but tapered it and that's where possible contact would occur........
