Where to buy a good engine (GSX 750 ET)?

[gsx750_80]

Hi

One year ago I bought a 1980 GSX 750 ET, quite similar to this
one http://www.bikez.com/motorcycles/suz...x_750_1980.php
. When I should change the gasket beneath the valve cover I found
that 4 bolts holding the camshafts were missing (threads destroyed).
The engine seems to be in poor condition, though it runs nice and ok.
Does anyone know a shop (or other place) where I could buy an
engine to replace the old one (or all parts from the cylinders and up)?
I need to get it sent to Norway (Europe).
Any other engines that would fit directly into the frame?
(Probably the 1980-1981 GSX 1100 engines would.)
Thanks, and best regards,

GSX750

Have you thought about putting in helicoils to replace those threads? Easy to do and probably your cheapest / easiest option. If you start building a motor from bits the chances are the cost will run away with you.

Next option I would think about is popping in an engine from an 1100. Again, easy to do (though watch your back - these engines weight an lot). 8 valve 1000 also fits easily.
