Re: New engine help

Did you happen to disconnect the ECU? Check to see if it's connected securely and properly.

Re: New engine help

^^This is not great advise as to how to set a distributor.^^ You only have a 50/50 chance of being on TDC #1 cyl.

The timing marks line up for both TDC #1, and TDC #4 cyls. Lining the marks up is not enough. You must ascertain Which cyl's TDC (#1 or #4) the cam (valve action) is on. You can determine this by one of two methods:

A: With driver side valve cover removed, rotate crank until #1 Intake valve closes, then about 90º of rotation later the marks line up. This is TDC #1.

B: Remove #1 spark plug. Place your finger over the hole. With a remote starter button (or a helper on the key) blip the starter in little bursts while watching the balancer. When you get the "PFFFT" of compression, look , and you should see the mark getting close. Usually within 45º. Crank up to TDC by hand.

These are the two methods I use. I'm not aware of any other methods that are as sure-fire as these.

I didnt know this, i always thought when the timing pointer is at 0.0 then #1 cylinder is at tdc.
I have done distributor swap maybe 5 or 6 times on the ty and it all seemto be fine, well so I think.

Re: New engine help

Well thanks for all the words of advice. I had the timing right. This was my 1st go around with roller rockers, they were too tight. They are a pain in the ass!!! Just alittle too far and they hang open. So needles to say got them adjust right and viola, vrrroom, vrrroom. I should of had the wife video the first start up, it was great, and I looked like an asshole jumping around my garage with excitement. LOL The book I have said to turn the nut one full turn, that is way too tight. I went about 1/4 turn and locked them down. FWIW Harland Sharp roller fit under stock covers. I was worried, they're close but they do clear. So for now they boost is turned all the way down, lucky to get 1 lb, and I've been granny driving it. Two things, how many miles before 1st oil change and how long to break it in? The bearings, crank, rings, and valves are new but the cam and lifters are used. Any other words of advice are greatly apprieciated! It has been years since I've done an engine. but it is slowly coming back to me.

Congrats on getting it running. What oil are you using for break-in? Not synthetic...Jim

Nope. Rottella-T 15/40. I went with reccommendations I found on here. I'll prolly continue to run it since it has a good ZDDP count. Plus I get it for FRREEE. LOL

Re: New engine help

It’s been bother me since this post, so I had to recheck mines. To my surprise it’s correct, about 80deg after #1 intake valve close the rotor point to #1 cylinder.

I don’t think the engine would even start if it was pointing to #4. I don’t remember exactly but I think had to rotate the crank to get the distributor to fit right. I am thinking If you don’t have the correct TDC (#4 instead of #1) will never get the rotor to point to #1 cylinder.
