Long story short, we replaced parts on it to get it running, plugs, pump, cap and rotor, etc. We then found out it was leaking gas from the fuel return lines. Well, that runined the bearings in the engine, and I am upset.

Now, my question is. Do I grab a lower mileage 4.3 from a junkyard with a 30 day warrenty, or do I swap in another motor?

What are some other good candidate for a swap?

 

5.3 or a 5.7

 

Would a 5.3 fit into a 1994 4 door blazer?

I shouldn't say this, but I do have a 94 Trans Am w/28K miles, built tranny, etc.

I have considered swaping that, and putting a turbo 5.3/6.0...I know I can get 5.3's cheaper than Lt1's right now.
