1986 4.3 k15 to 350 engine mount questions

Hey all hoping to pick your brains on what I can do about my situation.

My K15 originally had a 4.3 v6 with a SM465 and I am trying to swap on a 350 v8 from an automatic 2wd truck. I have most things figured out until I was looking at my existing mounts and the ones on the two wheel drive were so different.

I know these frames were built to take any combination of engine but I was wondering what I would have to do to my v6 mounts to get the 350 to switch.

Can I just move my mounts forward one hole?

Should I buy a new set of mounts and if so which’s ones as everywhere I look it’s either for an LS swap or LMC truck only sells the 2wd frame mounts which won’t work for my 4wd frame.

Any help is appreciated and assume I don’t know very much in aftermarket options. I was hoping it would just fit in but in my infinite wisdom I forgot the V6 sits farther back.

Has new injectors and rebuild kit in it. Has been sitting for 8 months

Curious if the exhaust smoke and drooling injectors is an issue. Seems to start and run just fine.
