The 89 and 90 trackicks have vac. adv. distributors. You could just swap the samurai distributor and housing onto the back of the 89 trackick head too.
Are you planning on just running the samurai carb? If so, then you could just swap the whole samurai intake onto the trackick head. Then you wouldn't have to run any of the 1.6 stuff (other than the block and head).
