Engine 302 production block selection

The few mexican blocks that I see pop up have been ridiculously priced....
Yeah, I'm kinda thinkin' an 'early' block is most probable. But... People with A4s, R302s, and Boss's almost always know what they have. Mexican blocks can still slip through the cracks if you know how to spot 'em. So, good to know what to look for.

Honestly, I don't by the 'nickel content' theory. I would hold them with the exact same category as the early blocks until I see evidence otherwise.

Mustang5L5’s progress thread - Part 3

Awesome. I've really put off the Quarterhorse install on Black Jack. Inspire me! Actually, now that I have a wideband and can see what it's doing, I've been so damned impressed with just how spot-on the AFR is at idle, part throttle, and WOT, just from the "calibrated' Pro-M MAF, that the Quarterhorse install became a lower priority than other concerns.

Have you actually measured your AFR? You might find out like I did that there's not as much room for improvement as you think. I still want to do the install & start tuning to clean up idle, hopefully learn to reduce surge, maybe pull a little timing at part throttle, and to learn the ford computer, but it's not gonna be a night-day difference for Black Jack.

Transmission fluid question.

When I bought my Cobra, everything was original factory, including the trans fluid. The T5 shifted okay, but it was unpleasantly notchy and didn't like finding first at a stop light when hot. When I tore it open to replace the 8-tooth speedometer drive gear with a 7-tooth gear for more ring and pinion choice options, I refilled it with Royal Purple MT fluid on a recommendation from a friend who uses it with heavy machinery transmissions. I also contacted Royal Purple directly to ask them if I should use their ATF or MT fluid for a T5. They said to use the MT fluid and that it already had friction modifier in it, so I didn't have to add any like you do for the factory recommended ATF. This was the first time I've used Royal purple for anything and I was skeptical, especially at the $17 / quart price tag at the time (it's probably way more expensive now). However, I was blown away by the difference. It's very noticeable. It feels so much smoother after switching. It's notchy, but in the good smooth notchy way you want from a muscle car manual transmission, and the resistance to find first gear when hot has completely gone away. I never would have believed that the fluid choice could make such a difference, but it does. Maybe my factory fluid was just old and warn out, but the improvement in shift quality / feel is completely worht the extra $$ in my experience.
The issue could have been that the fluid in the car when purchased was old and never changed and any new fluid would make it seem better.

Picked up a custom shift knob

T
I like that a lot. Link?

Wish it didn’t have the logo though

Search universal. Took me a while to figure it out. The logo isn't optimal, but you may not find another shift knob like it.

5 lug swap brake identification needed

I went down to finish up the job this morning, I left the parking brake cables for last thinking it would be a 10 minute job. It seems like I have to cut a notch in the moan brackets now so the cables can fit.. is this normal? Or am I doing something wrong here? I needed to pull some slack out so they would reach, they reach the hole but can't go in because they hit the brackets.


From another thread:
E brake cables, there is a possibility that you can re use your factory e brake cables by relocating the brackets so they dont make contact with the wheels, what i did was buy some steel zip ties and attach the brake cable to the calipers and zip tie the loose part of the cable to the lower control arms, then relocate the bracket by drilling 2 holes one for the screw and one for the retaining fold (you'll see what i mean when you get down there) if you go this route you do not need to modify your e brake cable, now this isnt guaranteed to work(worked on my 88 but not my 87)

Help me create the "Surging Idle Checklist"

Just to add to this. The 94-95 mustang has more diagnostic capabilities. You can hook up a scanner and get live data and run special tests.
Older snap on scanners can be found on eBay.
Also a tfi module that is breaking up can cause a surge or stumble.
Below is a pic from my scope showing a module that's cutting out. Green trace is the pip, yellow is the coil trigger from the module.
