You're good to go following my HO into Renix instructions.

thanks cruise

its a murf. but got everything swapped

now how do i go about swapping the dizzy. and.making sure its in time?

Do this to both engines to start with.

Setting Your 4.0 at #1 TDC
　

With #1 spark plug removed, turn the engine over clockwise using the 3/4" front crankshaft bolt. You will see the degree marks on your front cover. You will see the timing mark on the balancer. Mark them with chalk or white-out. While turning the engine over, put your finger/thumb over #1 spark plug hole. As the mark on the balancer approaches the marks on the front cover, if you are coming up on #1 TDC, pressure in the cylinder will push on your finger. If there's no pressure, you're at #6 TDC and need to crank the engine over until you see the marks coming together and you get pressure. Set the mark on the balancer to the 0 mark on the front cover.


#1 is denoted by the yellow connector in the photo. Firing order is clockwise 1-5-3-6-2-4

neither engine is in the jeep

update got the balancer at 0 on number one but the rotor button is a hair past 1 on the cap

Is there a distributor in the "new" engine? If so, bring it around to the same positon.

that is the new engine. there was no dizzy

Well, you can be on #1 or #6. Only way to tell you're on #1 is to use the instructions I posted.

ok i turned crank until it stopped blowing my finger out the number 1 hole have the harmonic balancer on 0. so i take it i followed the instructions

Yep. You did. Drop the dizzy in so the rotor is just past the #1 terminal on the dizzy cap.
