Glad to hear you're still at it and looking forward to updates!

Actually, I think I got confused with the diff mount that I used. I did a bit of searching and I believe it is a GM transmission mount like this one: https://teamenergysuspension.com/product/energy-suspension-3-1108r-transmission-mount/. Dimensions of the mount can be found with a quick Google search.

I would replace that stock transmission mount with a solid poly mount. The mount I'm using is from some sort of Jeep...I believe. I've slept a few times since then :D. All I had to do was slot the two mounting holes to make it fit the transmission (z32). I wouldn't sweat those marks on the clutch and PP.

I meant to reply earlier but yah, I think you put too much grease in there. There is a diagram in Haynes and probably the FSM showing how much grease to put in there.

Nice! My son got one of those for his l6 build. It's definitely a nice manifold. Are you simply drilling a hole in the manifold flange or slotting it so that you can pull the manifold without opening the coolant system? I would avoid cutting all the way thru the manifold flange. I did that on mine and it immediately bowed out of plane due to the internal stresses from all the welding. I managed to bold it on as-is without straightening/stress relieving it but it's not ideal.

I would think that you would be good with those nuts, from a secondary back-out prevention perspective, but they may rust eventually after the copper burns off. It's best to know the materials so you can torque them properly. If you go with Inconel, you're going to need high strength nuts so you can get the torque high enough to stretch the stud and preload the joint.

If I had to guess, the copper nuts probably turned soft during high temps, lowering bolt preload leading to back-out. You might want to consider high temp stainless locknuts - the type that are deformed. Also, torque them to at 60 - 80% of the stud yield strength as a primary means of back-out prevention. Recommend lubricating them prior to installation to prevent galling, especially if you have stainless-on-stainless.

Gotcha...I didn't realize these even existed now. Upon a recommendation by TonyD I bonded a MSA performance gasket (I think - its light gray in color, not sure what it's made of) to my valve cover with weather strip adhesive and apply anti-seize to the head size to keep it from sticking. It's been working well for ~10 years.

I am curious why you don't like this setup. It should make removing/re-installing the valve cover easier, assuming you don't have to rtv the head side of the gasket.

Hi Mark! You will need a fuel pump suitable for fuel injection like a Bosh 044 and an adjustable fuel pressure regulator like ones made by Aeromotive, AEM, etc.

I agree. I'm also using an ACT heavy duty PP and street disk. It's holding up to 300+ HP with no issues, but I'm also not dumping it on slicks either. So YMMV depending on your setup and how you dive it.

Oh, wow that's scary. Thank gawd it didn't come off while driving! Are you positive that you didn't bottom the bolt in the crank instead of clamping the pulley? Also, the pulley seems like a loose fit on the crank snout. It should be a very snug push/tap fit with very little to no slop.

I've also seen folks with modified fan shrouds. In my mind adding cutouts/flaps and especially louvers should be avoided unless you know you need them. You want all the air that the fans are moving to go through the radiator. Adding louvers shortcuts the flow path by allowing air from the hot engine bay to recirculate through the backside of the shroud then again out thru the fan housing, bypassing the radiator and reducing the cooling system efficiency. Adding flaps seems better but only if they actually seal, otherwise they just add another potential leak path. Anyway, thats my $0.02 on the subject.

@Dat73zI believe so. The few times I've driven it since adding the fans, the ECU shut off the fans while moving because the coolant temp dropped below the 167f set temp. The ECU turns on the fans at 170f and turns off when the temp drops below 167f. I'm running a 160f thermostat.

She is up and running again. I finally finished installing dual 10" Spal fans, shroud, and BHJ front damper. All of that stuff was sitting around for a while waiting on my lazy a$$ to install them. The below link should take you to a video of the car and fans running. Note my classy radiator expansion can! Probably should get a legit one at some point... Dual 10" Spal Fans The fans are a bit loud but so is my exhaust so it's not bad. It's difficult to tell how effective they really are because fall weather but my gut tells me that these fans are much better, especially while idling. I can see the temp gauge slowly drop, which is not something that happened with the clutch fan. I can also feel significant air flow in front of the condenser at idle and there is cool air coming out of the interior ducts. Previously interior cooling was marginal sitting idle...but again it's not nearly as hot outside. I guess I'll have to wait for a hot day, or summer weather to know for sure.
