The Best V8 Stories One Small Block at Time

If it turns out to be a ring issue I think I'll have tsp make a 383 out of it unless I can pick up a 408 or something from the classifieds.
I got one of these to use when I was replacing valve seals and it works really well, much better than the tim's tool I used before. One of the problems I had with the screw-down type of compressor was that if the spring was a bit off-center when putting them back in you had to unscrew/rescrew and try again which took forever. With this you just let off a bit and try again. I put a 15 inch piece of pipe over my ratchet and just held it down with my arm pit while putting the locks in and knocked out the passenger side heads pretty quickly. It's the lingenfelter tool.
I used some amazon credit I had to pick up the Hellwig pro-touring rear bar to compliment the ridetech musclebar I ordered for up front. The Hellwig bar is pretty light weight but has a nice finish on it while the Ridetech bar is much more substantial feeling but the finish isn't as nice. The both look to be well-made though, and I like that they are both from here in the states (or at least I think they are). The lower Strongarms are nice-looking as well.
After weighing the cost of having my motor 383'd I had decided it might make more financial sense to just buy a motor/trans combo but the one I wanted sold, so instead I picked up a T56 from some guy here in town. Came with a new slave, a billet flywheel with a new disk and the bellhousing. I'll just think of it as my silver medal. Still need to buy a clutch, master and a shifter but am in no real hurry.
The Hellwig bar was only $210 shipped at Amazon. Pretty reasonable all things considered. The bolt threads were painted though, which is odd (at least in my mind) but I'll hit them with the wire wheel.
The finish
More or less how the musclebar ties into the lower control arm. The posi links are pretty cool and there should be plenty of tire clearance for whatever I end up with.
The bar has three main pieces. Perhaps at some point center pieces will be available in different rates, sort of like a splined bar. This is just a guess on my part.
T56 stuff. The trans itself even came in a fancy deluxe carrying case, aka a tupperware bucket.
I need to figure out what exactly the reverse lockout does and how to hook it up. Speedo output is a non-issue with the gps gauge, but I will need to get the vss hooked up and make sure the computer gets whatever info it needs. With no real way to cut or bend metal of the required thickness I opted to buy this clutch master bracket from ebay. Some guy sells some for $60 but this was half that and I didn't really see much difference - http://cgi.ebay.com/ebaymotors/ws/eB...84.m1439.l2649

Went out to pull the heads today thinking it would be a quick and painless operation, which it was for the most part until I realized that to get to the lower bolts I'd have to take my headers out. Pulling heads with the motor in the car sucks *** compared to working on a stand; I don't know why it took me so long remember that. Anyway, at that point it started raining so I said to hell with it and headed back into town. All things considered it might be best to go ahead and do the brake swap once the headers are off, since I'd have to remove the driver's side anyway to relocate the distro block. The plan was to be able to drive the car by Oct 8, but at this rate I'm thinking I should shoot for a year and give up on a specific day.
The guy I bought the trans from told me about a place by the fairgrounds called TN Clutch and Supply so I grabbed the flywheel and headed down there. Given that I know nothing of clutches or what goes inside them I just told him what I had and what I wanted and let him do the rest. This looked like the kind of place that would know a little bit about clutches. What I ended up with was a double-something ceramic and organic deal, some new bolts, a black plastic thing for aligning pieces (I guess) and a bearing, and done in under an hour.
The speedhut gauges I ordered a week and a half ago are still not here, and according to the live chat they won't be until sometime next week. She said I could pay more for expedited shipping but the idea of paying extra just to get what I ordered less late is pretty stupid. Kind of sucks that so few companies actually deliver on what they promise. If only Summit and Amazon could sell everything I want this car would be finished already.
Also, mainly so I don't lose track of it, here is a link to a thread with some helpful info for people swapping from a similar trans to a t-56. It answered most of my vss/ reverse lockout questions. https://ls1tech.com/forums/conversio...harness-q.html

How could there be this much build up so quickly? One cylinder I could maybe understand, but the crap being all over and all the plugs looking foul makes me thing the problem is more global in nature than something like low compression in one cylinder or one piston having bad rings. If anyone sees anything or has any ideas feel free to comment.
Some of the cylinder walls do have a kind of crusty ring very near the top. Does that mean something?
To this point there has been no oil in my water or water in my oil or anything like that. Just as a side note, pulling the driver's head first will help keep your starter from getting soaked in coolant when you pull the passenger side.

Wires look easy enough to manage.

I did get my heads back yesterday and if I can get the bolt holes cleaned out today I hope to get them back on today. It looks like a nice day so I'm hoping to be able to drive the car out to go watch football later. If it still smokes I'll pull the motor next weekend, throw it in the lake, close the garage door and find a new hobby for a while.
This massive pile of parts in the living room can just continue to sit.
