Morels. I got the Comps from Butler, but it was like 18 mo ago, and they only warranty for a year, asked me to call the manufacturer, which I did, and to call them back if they couldn't help me.

Butler did agree to swap out the bad ones, gave me an RMA, but I'm not trusting any of them. So I'm going to call them back tomorrow and just eat the Comps. I can't even sell them, except maybe the 2 pairs they were going to replace. The others I washed, oiled, and put assembly lube on, they have very minor scuffs from me rotating the engine and adjusting them, so can't sell them as new.

So received and replaced the lifters, the pushrods won't be here until Wednesday. Was able to reinstall intake, and am about at the point I was before I discovered the collapsed lifters. Whew.

Also started the exhaust install. As a recap, it's a Pypes header-back 2.5" X pipe kit, with thru-valance tailpipes. The correct type hangers came in, as well as associated hardware.

Tailpipes line up very good, and can't tell at the moment if the typical inboard 'tilt' on the driver's side is there, first guess is no, but will see once it's all hung.

Since I have a 4L80E, and the crossmember is set back further than stock, In order to get the X in there, it needs to move back, and the included collector extensions aren't long enough. Uhg.

So ordered a pair of collector extensions that are 18", which is 6" longer than what was provided, will probably have to trim them about 1". Those should be here sometime late in the week.

Update. Got the exhaust hung and initially adjusted, haven't put any clamps on yet. The headers, Dougs, are not perfectly parallel to the frame rails, making the exhaust a challenge. The driver's header is slightly tilted towards the trans, not sure about QA with Doug's, but it was not making me happy.

To get it all to line up as best I could, the X is slightly tilted, and due to the tilt, in order to get it all to line up, the driver muffler is tilted. Hoping the shop I', going to have weld it up can fix it, fingers crossed.

On a positive note, the engine is near ready to fire, have it all setup, just need to do plug wires and looms, dump some gas in it. I'm short one loom, ordered some, should be here Thursday.

Will go over the ECU config, double check everything, do the TPS sync, and will fire it this coming weekend.

Yeah, sorry, busy as all at the moment, lots going on. Anyway, so Saturday I got the ignition all setup and installed, dizzy, plug wires, looms, and was going to do the O2 sensor which I ordered from Summit on eGay. So opened the box, pulled it out, and the bag it was shipped in was open, and when I pulled it out, there was carbon on the tip, so it appears as if it's used. Bummer. It's a NTK one, the $275 variety, so going to send it back and get a 'new' one. (Didn't want to install a used one, period). Long story short, no startup this weekend.

Basically, all that's left to do for the start up is exhaust clamps, add gas, and verify the ECU config.

But I did get some shots on the plug wires, and the looms installed. Just a recap, running the PRW type valve covers, and the bolts go in thru the top rail of the covers, and are recessed. Makes it difficult to do wire looms, but used some Moroso BBC ones and it looks good, will do the trick.

The 90 degree brackets I had to bend to make work, and used Moroso regular clip on separators along with the bracket-type looms. There's a close up of one of the bent brackets to give you an idea.

Here's an interesting tid-bit that some may find useful.

I have the large tube Doug's round port headers, and while completing the ignition install, went to install plugs, and found that I couldn't get my usual thin wall deep socket (5/8) on the #8 plug, because a header tube was preventing enough space to tip the socket on there.

I was like 'Eh, no biggie, will grab the plug socket with the wrench fixture on the end' . Nope. That would fit either, and was left having to 'make' a socket that was able to fit.

I used the wrench ended plug socket, cut it @ 3/4" shorter, and since it wasn't a thin wall, had to grind the first 1.5" of the body thinner. That worked, but has anyone ever had this issue before? (PIC)

I had the 1 3/4 tube Doug's on before, didn't have this problem, so guessing it's an issue with just the 1 7/8 ones?

I spoke to you before I bought the Doug's RP headers for my brother's '70, they are 2" primary tubes and we use a wrench for the #8 plug. No need for a special tool. What was the difference in PR length using the Morel lifters compared to the Comp POS lifters?

I think I may have gotten a set that was on the edge of tolerances. The driver's side is slightly closer towards the trans, and the end is slightly tipped towards the trans as well. I had to dent on tube slightly to clear the engine crossmember too, think I posted that in this thread.

So with e-heads, 69 400 block, it's been slightly decked for @ .006 deck, and the heads have been touched up once.

With a Lunati VooDoo 713 HR cam, the Comp 857s required a 8.8125 pushrod, I rounded down to an 8.800.

The Morel lifters required a 8.5925 pushrod, and I rounded ever so slightly up to an 8.600 pushrod.

My pushrod measurement method is for valvetrain/rocker geometry, which in turn gives you the best pattern on the valve tip. Most people do it backwards, which IMO, is wrong.

This is the method I follow:

https://www.youtube.com/watch?v=o5is9BsH5OU

That one is from Straub Racing, but the method is the accepted method among all top engine builders and experts on the subject. If you went to a legitimate technical training school, this is basically what they teach you.

Have you started the motor yet?

No, unfortunately, I'm having a TPS Autoset issue with the DBW setup, have posted on the Holley EFI forums, was suggested I call support, they say it can only be 2 things, the throttle body or the harness, but I question if the person I spoke to was correct.

Today I removed the driver inner fenderwell, and checked the entire DBW harness, no signs of damage, thought I may have pinched it during assembly, but that wasn't the case. I did some preliminary checks on the throttle body with an ohm meter, all looked right, but haven't dug deeper yet. Posted again on the Holley forums, and will call support Monday again and push to get better troubleshooting steps.

I was also having an issue with the vette PWM fan controller, wasn't working. Have been in contact with. Andrew70, he went over a bunch of stuff with me (thank you Andrew), and couldn't find the issue.

I was determined, and continued troubleshooting that after going over the DBW stuff. Originally, when I first applied power to the car, the fans came on, and I unplugged the controller. I at one point went back over it, and realized that on the I/O harness plug, I had plugged the PWM feed wire into the connector 'C' position, and it was supposed to be in the 'G' position. (my eyes aren't as good as they used to be!). I corrected that, and plugged the controller back in, but wasn't working.

So today, after going over all the wires again on the PWM and I/O connector, verifying it was correct, and for grins, plugged in a spare PWM controller I had, and boom, it started working. So guess when I had plugged it in originally incorrectly, it fried the controller. I had put it on a +12v output, and it requires a -5v signal feed.

So I got that figured out. The ECU won't fire injectors or ignition if the TPS doesn't check good on power up, so until that's corrected, I'm in a holding pattern on the start up. It's driving me nuts!

Tomorrow I will knock out some other items on my to-do list that need to get done, just so I'm moving forward. Monday I will work with Holley and see if we can get the DBW stuff figured out.

Update:

Have been struggling with the TPS Autoset on the Dominator EFI using a DBW throttle body, as well as finding time during the busy holidays to work on it!

Last week, I started drilling down on the DBW harness wiring diagram, which is in the instructions, 558-406 Holley part number. Then I noticed, while skimming the entire doc, that the harness only had 2 TBs listed as 'compatible'. Hm. I remember specifically that there being a handful of supported TBs in the Holley Dominator 'Selector Guide', which I pulled up. Sure enough, there's a big list.

In the selector list, my TB was listed, as I knew it would be, and it's not listed in the harness' instructions. Ok. So I go to look up the TBs that are listed, and, the are both 'discontinued' GM parts, but can be found NOS. Uhg. They were not cheap.

So tried to figure out a work around, and basically, I loaded an LSX TB config file, and was able to get it to work without changing any parts. Cool.

This week I need to finish my ignition map, but will be ready to fire it off this coming weekend. Finally!
