hey, i asked mickey dunlap what he thought i should get for an engine kit.

------------------------------------------------
I would recommend our high compression 80 over piston for $115, valve springs at $110, cam at $150 (exchange) and an oil cooler at $95. A bore job is $45.

300EX Bore 74mm - Stroke 65.5mm = 281.7cc

.040 over = 75mm = 289.369cc

.080 over = 76mm = 297.13786cc
