Well, my Jag parts finally came in. It's back on the road with new timing chains and secondary tensioners along with some new ball joints and swaybar end links. I'm surprised at what a nice driving car it turned out to be. I'll be headed to the DMV tomorrow to finish the paperwork. Once the title comes in it's up for sale. My dad will be driving it for the next few days.
...and here's why:
Last time you saw pics of his daily driver '64 El Camino he was running a Paxton supercharger on his LT1. Recently (I suspect mostly out of boredom) he's been focusing more on fuel economy. The supercharger came off and he had acouple other PCMs flashed by my uncle. The final conclusion was that lowered compression and the automatic were holding him back. Since the current LT1 has had the pistons replaced with lower compression pieces to make it more blower-safe, it made more sense to just replace it rather than tear it down again. My dad is the master deal hunter! He came up with another LT1 that was claimed to be a low miler along with a harness for $200. I tore it down to reseal and detail it and found it was immaculate inside. I would estimate 30-50K miles on it. He listed the engine and transmission he's running and had it sold (took a deposit) to a guy who wanted to put it in his '40 Chevy. I pulled the engine and 4L60E, swapped a few parts and installed the new engine.
^^Ignore the missing A.I.R. plugs and the "filled" intake elbow. Suitable replacements are on order.^^
Here's part two of the process:
What? Why would anyone chose an S10 transmission? Aren't those super weak? Stick with me, there's a few reasons for this choice.
1. My dad drives like an old man 99.98% of the time.
2. This car will never see track time. Economy is the focus here.
3. The engine is bone stock and will likely remain as such.
4. The S10 version of the T-5 has a forward position shifter that is better suited for bench seats.
5. The s10 transmission is the only GM version of the T-5 that uses the standard front bolt pattern in the standard orientation. The early Fbody version is canted at a 17* angle. Later Fbody has a Ford front pattern.
6. The gear ratio is a great match to the 2.56 posi that he has in the car. Almost the ideal 10:1 compound first.
7.
This particular T-5 is a relatively rare late-'93 model. It IS a WC not the weaker non WC that people say are weak. Never heard of it? Don't think it exists? Here's proof:
I pulled the input shaft out to have it machined down to the standard Saginaw/Muncie/T-10 dimensions and verified that it had the fiber lined blocker rings as opposed to the regular brass synchros. The Splines needed to be cut back about 1/4" and the end of the pilot was shortened 5/8" and the retainer was also shortened. I used an M-20 to match up all the dimensions.
By using a regular '86-up (one-piece seal) flywheel and 10.5" clutch set it is feasible to replace this transmission with any of the GM 4-speeds if the desire should arise. The only part that would need to be swapped out is the clutch disc. I contacted Otts Friction to see if they could build me a 14 spline clutch disc in 10.5". As it turned out, one is available but I'm not sure what the original application is. It's being shipped from their supplier in Minnesota and should be here on Thursday. I'll post up the final results. Hopefully all the parts will be in by the weekend so I can get it back on the road. Until then, the '64 goes in the bullpen.
I got a call from my dad this morning. I guess the '40 Chevy guy backed out of the deal and forfeited his deposit. It's for sale again for now but might end up in my brothers '36 Ford pickup.
