f54 n42 into 79 zx F/I

[green260]

hey all new to the forum, ihave a 260z w/ blown engine. i recently found a 79 280zx im going to buy. right now im having a f54 L28 n42 head being rebuilt. its getting .040 bore new bottom end (seals- bearings - rings- pistons-polished krank&balancing)

replacing valve seats&guides -etc etc & a mild cam w/ rocker arms:classic: just wondering what it will take to put the rebuilt engine into the 280zx F/I i have all the stuff for carbs out of my 260z (round top SU s) im curious to hear from anyone who has done this if there are any problems w/ the swap or should i stay w/ the F/I on the new rebuild ( f54 L28 /n42) the zx has all power (windows-mirrors etc.) would it be that hard to complete w/ little or no problems. (as w/ the power components) the zx runs ok now but has a stumble or miss at cruising speed ,not on accel,but just going w/ a little pedal .when you mash it it goes fine no stumble,could be wires or dizzy cap or plugs or well you know, all will be replaced in short order when i get my hands on her!

anyhoo been reading for months and have taking alot from here any help i can be ,just ask! all your help has been great thanks guys, chris
