... I have a 375hp 400 cid small block in my 1970 Chevelle/Nomad
I've been self recalibrating all my life. It's that 5 - 7% error factor that has really fubar'd my recalibrations! I am anxious to read about his "self recalibrated" budget rebuild getting past break-in and more than 40,000 miles. Gnarls.
It's funny too, I've had the last few go way longer on less effort. They were more like sloppy hone and re-ring jobs compared to that one, which was pretty complete. I put over 60K on my 3RZ before I sold it and about the same on a 22re before I sold the truck. Both never even hardly burned any oil with fresh rings on used stock pistons. Neither of those got a questionable 20r head slapped on them and were tuned up down and sideways though . You might have something on the RA thing, since those done with a hone in the garage would have been different than the bored block from the machine shop. Maybe I should make a habit of running that old hone through my blocks just a bit when they come back from being bored.Can't say anything until I get to tear down that 22r though
I keep justifying things on my rebuild by thinking about how many engines have been slapped together or rebuilt in some small town with a primitive machine shop. I'd like to do everything racecar perfect, but it's just not going to happen.
I think H8pvmnt's engine should be a real eye opener, can't wait to see it prove you wrong.
Hate to blow your bubble Gnarls, I've been working on cars since I was 8 (more years back than I want to say). I have the machine shop do the boring and hone, then I do the cross-hatch myself. I set all the ring gaps and balance each piston set and rods. Sometimes I'll do the crank if the engine seemed rough at idle before teardown or I want a high winder. I do this in my garage with my scale, not in some fancy machine shop. My engines always do over the 100k mark, my present is sitting at 214k and counting. So chalk one up for the shade tree mechs. I think H8pvmnt's engine should be a real eye opener, can't wait to see it prove you wrong.
I hope so, but with all the DnJ parts...well I'll just keep my fingers crossed.
It will be fun to see how the orange engine does. While I don't consider it slapped together there were certainly budget compromises made, using certain parts and re-using others that happened to still be in spec. I am more interested in tearing down the other one though. Hopefully we can learn something from it.
Sorry G, not tryin' to get your panties in a bunch, just sayin' some guys can build an engine without an expensive shop emptying their wallets. I made a typo on my milage, it's 114k not 214 and counting. I've done the recycled parts thing inside the engine before, pistons-cam in new head-lapped valves-emorypaper polished cranks, to name a few, and they have all worked out OK. I'm not sayin' everyone will get the same results, just that attention to detail and cleanliness are probably the most important tools in your arsenal. Just my two cents and no harm or malice intended.
Two great advantages of the early Toyota engines is the relative simplicity of their designs and availability replacement parts. With some common sense, a good understanding of engine component specifications, selecting quality used or remanufactured components, a little help from reputable sources, and some pre-planning, gives an average DIYer - with basic mechanic skills and basic tools - the ability to successfully rebuild these engines….. and, it’s exciting and encouraging to see it and read about it being done. Gnarls.
Can you define pre-planning? How about preliminary-pre-planning? Doesn’t planning imply it happening prior to doing?Where I work we use the term pre-planning ahead of execution. It explains a lot of our issues if I assume we skip the actual planning step.
How long has it been since any actual work has been done to this truck?Again lots of talk and very little action Gnarly. Chop chop
my definition is relative to my experience from the time I decided to restore my truck after sitting in my garage for almost 4 years.I should have done way more research on just about every aspect of my rebuild and restoration. I relied on my years of experience and limited 22RE rebuilding knowledge.Example I didnt check to see what replacement parts may not be available.Example I didnt anticipate what condition of a truck sitting for 4 years would be in.Example I should have spent more time researching performance options.Example I should have spent more time thoroughly understanding the precise machine work that would be done on the block and WHY.Example I should have spent more time researching what replacements parts would be the best choice for my goal.And, I should have spent more calculating and predicting time and cost factors!All of that - to me - is pre-planning.I clearly executed my plan way before I had sufficient facts, and a valid and logical pre-plan compiled.My plan was to simply rebuild the engine with known components and increase the torque and HP in my target RPM range, restore it to as original as reasonable, and enjoy using it as my daily driver again.A preliminary pre-plan to me would be a concept of what steps I might go through.How'd I do? Gnarls.
One may have been for a defroster for the rear window. After market lights are another possibility.I know that my console has knockouts there for switches.
Does anyone know what these switches do, or did when my truck was new, or what they can do, what you may have them hooked up to if you have them on your vehicle? My truck is a 1986 SR5, XtraCab, 22RE, 5-speed. Here's photo..... https://imgur.com/a/95yWnAs far as I can tell, they are not connected to anything. Thank you. Gnarls.
Hey emsvitil,Can I reasonably assume that if the switches were there at the time the truck was purchased new, that they were hooked up to some feature? If the previous owner installed them, into the knock outs you described, I am puzzled what they may have been hooked up to and were switching, if anything? I will try to trace the wiring, if any. Thank you for your reply. Gnarls.
Glad you figured it out. For our edification, would you mind telling us, -- What tipped you off that they are factory? -- The all-important question: what did they hook up to?
Hey Lewis,Also, the switches match the one on the left side for the factory SR5 package bed light on the back of the cab.
It would cool to find a "feature" options list for a 1986 Toyota truck.. the kind you find on the dealership pages.
Hmmm. My 85, non-SR5 has a bed light, but the switch is to the left of the steering column, right beside the headlight dimmer switch
