Hi guys,thank you all so much for your advice.!!!
i think i will be very happy with a free revving motor around 90 hp.
To keep cost down as i already have a new 1289 piston and liner kit,i have decided to go with the 1289 option with lightened flywheel'd/d weber, mild cam ,prescribed headwork and extractors.
i would appreciate advice on porting /polishing and comp ratio work(to achieve 10:1 cr if required) on the head
and cam specs .
Just to throw the proverbial spanner in the works,would the r9/r11 head work wth the 1289 and where would i source one from, approx cost?
cheers brian
