Message	My motor shop is stating that there is no need to bore or upgrade to 88mm pistons for the motor has little wear and the cylinder walls are in good shape and to stay to 87.5mm stock... Is there any alternative reasons to just bore up to 88mm? im not trying to bore if its not needed...Any reasons or other comments welcome..Thanks as always tt.net [img border=0 src="http://www.members.aol.com/eriksu9/images/1badz.jpg">****472 RWHP/461 TORQUE ON 110 RACE GAS @21 PSI ****438 RWHP ON 93 OCTANE PUMP GAS/STOCK MOTOR**** ****429 FT LBS/TQ******************************* Also own: 2001 Harley Davidson Custom Softail Deuce 1997 Ford Explorer XLT V8 AWD 1993 300ZX 2+2 NA 1991 Yamaha YZ250 1985 Ford Bronco 3" lift, 35" Tires Sold: 1986 Yamaha FJ1100 1987 Nissan 300zx na(Z31) 1979 280ZX 2+2 1972 MGB 1968 Pontiac Firebird 1972 Nissan 240Z, dual webber carbs, etc
