i have a friend using the bluebird 910 SSS, stock twin SU. he's been using the sewing oil for a while. so i recommend him the ATF oil. the feedback is very positive, better acceleration, need to top up the oil less regularly.
shame i cant get my cam ground here in malaysia, as not many people love a datsun, its more toyota heaven here. btw correction, my solex is not phh 40,, but addhe 40 :)
good power mate, if u didnt say its an a12, i wouldnt believe it, its more like an a15.
good sound mate. off topic i think, what cam do you use for this motor? i own a stock bottom a12a with h89, and solex phh40. i think i can match that sound and more importantly that acceleration heheh.
