350 or 4.3 swap

Hey guys I'm new to this forum, I've swapped 2 22rs in my 87 pick up and just spent a main bearing in the second one. Looking to swap a 350 or 4.3 in it ! I just have a few questions. Which do u guys recommend ? I know the 4.3 is way easier to keep cool and has plenty of power. But I'm also balling on a budget guys. Give me a estimate total cost of the swap please for each. Thanks

i would spend some time looking at different swaps here:
https://www.yotatech.com/forums/f163/

a lot of it comes down to what sort of deal you can get on a donor engine/computer/harness etc
I almost had a good deal on a low mileage blazer from a guy at work. he was all set to sell it for $500 with only 77K on the odometer...than decided to fix the transmission

I'm in the middle of my 4.3 swap now. Things would be a lot tighter with a 350. I'm barely going to have room for an efan between the radiator and the motor. I think that could be fixed with some effort tho. My first truck was a single cab GMC with the 4.3. I really liked that truck so I'm hoping I'll be satisfied with the 4.3 in my 4runner.

I pulled my SBC out of my truck and swapped to a 4.3.

Very glad I did, the weight of the small block kills front end parts very quickly if you wheel.

Well; How about a 3.4 swap?

Myself a 3.slo with a DIY ecu would make sense. All factory parts, just buy a complete donor vehicle.

SBC would be "all factory parts". Just not from that vehicle, so would be a 3.4 I agree with a V6 you will have more room than say a V8. Really you could swap whatever you wanted to

Well, now I'm stuck with 2 options. Rebuild my 22r with the kit from lceperformance, bored .30 over, machine the block and crank, and port and polish the head. Witch would be a solid little 4cylinder rocket! Or do the swap to a 4.3 or 350.

I' quite happy with that little 22re. it does all I need. If I feel the need for speed I have an SRT Challenger.

Now LCE has good advertising but you can cherry pick yourself for a little more fun.
