ATK 258 Swap Steps

Hey all, just wanted to run something by y'all. I just ordered an ATK 258 from Quadratec today... Also ordered a Centerforce 1 Clutch, Weber 38/38 DGES Carb, DUI Distributor, water pump and a single exit Hedman Hedder. These will be the only new parts used on this engine (and of course new gaskets). Everything else will be taken from the old 258. I plan on doing the swap myself. I'd appreciate if any of you guys speaking from experience could recommend what order in regards to the steps I should take for this swap.

This is my first time taking on something like this, I know I'll run into issues. I'd just like to hear you all's experiences and ideas. Thanks!

Take pictures of everything before you start any disassembly. Those pics can save your bacon when you go back together.

Get some zip lock baggies, pen and note pad...bag and tag everything as you disassemble. You will be glad you took the time when you start putting the new engine together.

Take your time and have some fun; when its all back together and running....priceless!!

Take your time and don't rush be very clean and organized, work on one thing at a time. Pull off the front clip it will make things easier for you. I would build the engine out of the frame. Put on your headers, intake manifold set you distributor, clutch bell housing, starter and all engine accessories out of the Jeep so that when you drop in the engine its just wiring and hoses. It will go easier and faster that way.

Put on the new carb after you get the engine running cause its easier to trouble shoot when you make one major change at a time.

Trapshooter's suggestion is excellent and should be followed.

And good luck and enjoy cause when its done and running the sense of accomplishment is tremendous.
