Ok, I own a 1991 G20 Chevy Conversion van. Conversion done by Aero out of Kansas City I think. It has a 5.7 / 350 engine with 700R4 transmission. It's "fuel injected" but more like TBI I believe. I have been dreaming of someday doing an LS swap like others here on this site. It's a dream right now. Last year I changed the plugs, wires, cap, rotor, radiator and heater core. I just can't see taking out an engine that runs ok just cause it's a dream of mine. When the engine goes out (just turned 100K this summer) I will look at doing an LS swap.
Is there anyone who has taken the stock air cleaner and used the K&N air cleaner? Did you or can you tell any difference?
Can I ask what you have done to your stock engine to either increase MPG or get a few more horses out of your engine without breaking any bank account.
Well, I knew and still know the family I bought the van from. The dad put a "thrush muffler" on the van 20 years ago. Someone cut off the "cat" and put in a straight pipe. Single exhaust. I may dabble and get a K&N air filter.
It's my dream to find a 5.3 and do an LS swap like Jason AKA JAGI410 (amazing job and beautiful van)
I start to drool every time I go back and read your post and look at the pics you did of the swap. The one pic I am curious to see though is where you mounted the computer and how to wiring turned out.
I gotta tell ya man, the 5.3 completely changed the beast. I'm so in love with this thing. I've been helping a friend with his 82 4x4 Chevy van, and he has a healthy stock 350. Had my 305 ever run as nice as his, I may never have done the swap. But I'm so glad I did.
I mounted the computer under the battery. It's the perfect spot for it! I'll get some pics soon. I did all the wiring myself, it's really not difficult. The instructions on LT1swap.com were a huge help.
Hopefully you're coming up to Nats in Minnesota next year, you can see it in person!
