Question sbc 302 from a fuel injected 350???

I have access to a fuel injected 350 that is out of an '88 suburban. It needs rebuilt but its free so anyways... I was wondering if I have it rebuilt, could I have it made into a 302 using a 283 crank but still retain the fuel injection? Also, would I have a problem with the journal size? Any advice and/or help would be greatly appreciated. Thanks

A true 283 crankshaft has too small a journal to work. A real Z28 302 crankshaft has the correct journal size but the rear flange is wrong. GM has a adapter for this problem.

I too am trying to build a 302 from a 4-bolt 350. I can find spacer bearings to put a meduium journal crank in a large journal block, but as yet haven't found them to put the small journal 283 crank in a medium journal 350 block. If you find anything out, please post it so we can all share!!
Thanks

but why not just put in a 307/327 crank and add some long ford 300 I-6 rods they are 6.209 inches and costs less than 300 for eight with ARP bolts and floating pin bushings..?

and it will put your rod to stroke ratio at 1.9:1 just like the 302. with the added cubes of the 327
