When I first started this website. I planned to replace the vortec engine, with one out of my safari van donor. Then I got a 1990 k1500.\u00a0 I was going to shorten the frame and use the Tbi 350 in there. Which all was included on the dual fuel setup.<\/p>\n

Now the plan is to use the vortec and get rid of all computers. The engine has one, the tranny has one and even the transfer case has one.<\/p>\n

So to do that a carb and manifold plus hei distributor with a roller cam gear on the bottom would have to be installed.<\/p>\n

The 700r4 out of the k1500 and the transfer case and front driveshaft would go into the Yukon frame as\u00a0 well. I found out doing research I also needed a new flex plate and a spacer. The output on the vortec is .400 longer than on the TBI engine.<\/p>\n

Jegs<\/a> has one.<\/p>\n

Now I needed a carb I remember a friend having a Rochester sitting outside his house in the weather it had been there for years. Got it for free.\u00a0 But it is in bad shape. I also have one sitting in a an older camper van with a 350. I will pull that tomorrow to see what it is. Hoping for 704.<\/p>\n

Jegs again had a manifold that was a very reasonable price. With good reviews price $149<\/p>\n

I could use the TBI in the k1500 but that has a computer. I am anti computer. Do I think North Korea will send an EMP and wipe out every vehicle with a computer? Maybe but mostly I think they are a major point of failure. We depend on them too much. I know I am a computer tech.<\/p>\n

Back to the conversion also needed to switch out the fuel pump apparently the stock Yukon pump send 65 pounds the carb needs six. I think i will probably invest in a fuel pressure gauge and mount that in the engine bay.<\/p>\n

So now I am pulling the motor apart and getting it ready for the machine shop. they want a ton of money to hot tank and magnaflux. Magnaflux is neccesarry for the heads as vortecs are nototrious for cracking.<\/p>\n

Now I looked into the whole hot tanking thing. A lot of people out there are just making their own hot tanks with chicken wire and baking soda.\u00a0 I plan to do that and probably pressure wash the units.<\/p>\n

That will take off about four hundred dollars off the machine shop bill. Now if I could find a decent price on the electromagnet for magnfluxing I would probably do that too. Then all I need is the powder and a turkey baster, and I am off to the races. This way I don’t have to send my heads away and pay someone to tell me they are cracked.<\/p>\n

Now onto the machine work. I plan to remove the pressed in studs that hold the rocker arms. so the machine shop can tap the holes and put in threaded studs. I also learned the vortec heads . Need the area under the valve springs milled, so I can put in a cam with higher lift. Then the heads need surfacing.<\/p>\n

The block. I need new pistons to go down with the block to the machine shop. so they can bore them to match the pistons. So back to jegs I go and research pistons. They will cost about $32 each. Now i need to total everything and see if it would just be cheaper to buy a crate vortec. So much research to do. I will fill you in as I go<\/p>\n
