Congrats! Good old school stuff. When I bought my Elky over 10 years ago,it was in the 12's,427 BBC 4 speed. Kept whittlin' away,ended up at the end of one season with a 11.01 best. So pizzed off,couldn't get it into the 10's.
Pulled the old 215 oval iron heads off that winter,had Ladds Porting service do a little massage on them, put thinner steel shim head gaskets on,to bump the compression up a little. Next spring,very first pass down the track,10.97! Helluva feeling,never forget it.
Don't run it much now anymore,best is 10.45 128. Still a thrill for an old fart,yanking them gears!
