    What Oil Viscosity for Southern California Car?

    The recommended type of oil in 5.0 Mustangs was 5W30 in colder climates and 10W30 in warmer. Being 5W30 started seeing the market around 1985 there have been a lot of improvements like all lubricants. I've followed your build and its really nice and one hell of a motor for sure. For...

    What Oil Viscosity for Southern California Car?

    Owners manual 40+ years old and lubrication technology has advanced in 40+ years by quite a bit. I don't think it it is over thinking rather more like understanding what is available today that is better than the offerings 40+ years ago.

    You want to remove the vacuum line and cap it. Adjust the FP to 39 psig and then reattach the vaccum. My guess is you are a llittle high on pressure as typically at idle you will see about 30 psig or so. I am not saying this is the problem but its not helping. Also, check the vacuum line...

    Fox 1990 Mustang GT 5.0 A9L – Engine suddenly shuts off but immediately restarts when key turned

    I never noticed that. To me is sounds like relays clicking. Question, when you replaced the TFI module did you clean the old thermal paste off the distributor and install new thermal paste between the distributor and the TFI? Link to the paste I am referring to...

    What Oil Viscosity for Southern California Car?

    Man I do not run oil that you would run so I am of no use there. I run Brad Penn with all the additives being I live in an emissions hospitable state. You need some of the SoCal guys to chime in here. I updated your thread title to get the to come out from under their rocks....

    What Oil Viscosity for Southern California Car?

    I would go with what Bullitt347 suggested then. If you have good oil pressure then no reason to do anything else. If you have cats then stay away from lubricants with zinc, phosphorus, and sulfur as they have been shown to kill converters.

    What is the fuel pressure like? I am so suspect of any distributor but an OEM one when stuff like this comes up but it seems to be getting fire and its more like its over fueled.

    What Oil Viscosity for Southern California Car?

    Any mods and where do you live? Location can have an impact on viscosity. I run 10W-40 as it gets pretty hot in Oklahoma and the car never sees the road from about mid-November through mid-March.

    I use studs on the lower to the heads and completely stud the upper to the lower. Makes gasket alignment super easy and zero vacuum leaks.

    speedmaster new 302 block?

    The seller is a great guy to talk with on the phone, really knowledgeable, and has really good reviews on FB so made the decision to go get one. These are not blims and come complete and he has built one so sounds like the real deal. The way he talked it sounds like this is more than likely a...

    So I use brake parts cleaner on a q-tip and very gently clean the heated element. After that I hose it down with MAF cleaner and let dry. Last time I cleaned one I could literally see a light build up of dirt on the element. This was on the 80mm OEM MAF off of a 2000 GT from a salvage yard...

    I was going g to ask him if they are still bagged up and if this is a one time deal or if he can get them down the road as well.

    speedmaster new 302 block?

    Looks like I may be headed up there this Saturday. Anything I should be looking for on the block? I don’t have an internal mic or any of that gear so it making me a little nervous. Was going to see if he and I can talk first and go over some details.

    Sample tube info from Noobz: https://stangnet.com/mustang-forums/threads/c-l-maf-sample-tubes.898954/ C&L sample tube install instructions: https://lib.americanmuscle.com/files/cnl-maf-8993-install.pdf I may have asked this already but have you cleaned the MAF sensing element?

    Noobz beat me to it. I was Making good and sure I remembered what a C&L looked like. I had a BBK cold air and if you clamp the blue boots down on a 55mm housing it’s ugly looking as the stock MAF housing is about 2-1/2” OD vs the boots being around 3” ID. Those boots are tight which leads you to...

    I would bet money that is a C&L meter with a 30 lb sampling tube with the factory MAF sensor.

    speedmaster new 302 block?

    Well I sent him a message to see when he would be in KC. I’m a little under 4 hours from there and I would rather go up there and see the block in person rather than get it via freight and it not be what it is supposed to be.
