I recieved my OSC CU161 rad, 33" wide, I can fit 34" with the cutting I did. I like that it has thread in plugs, some have a crappy rubber plug and two different size rad hoses will fit on the top fitting. I am betting my gauge will take forever to hit 200 now.

Well the rad is in and fit as hoped. I took it for a drive, the 71 bottom hose won't work, kinked and pulled away causing a leak. Need to order the proper lower hose.

I had a hose off a 83 Delta 88 that came with the 350. I cut it a bit and it fit decently, still bleeding the system.

New gauge in, reads the exact same as my temp gun. It runs between 195 to 205, 210 at the highest, should be the stock 307 195 thermostat. The fans drop it from there pretty quick in town and now has plenty of heat inside as well.

Well, I took the 88 for a good dig, pretty sure the lock up is now working. Floored it like I have been doing and I heard bad belt sounds. Pull over, belt half shredded and GM with their F***ING wisdom, it sheared off the A/C connection. So now it needs another clutch. Get my wife to start it, something is a miss, I look the water pump, none of the bolts are tight! I probably missed tightening them, either way lock washers and blue loctight was applied. My Wife made comments of why I fill trunk full of junk instead of valuable stuff like fishing tackle, she saw why today.

Well I tested the old gauge, it maybe reads 10 high with boiling water, so I probably had an air lock going on.

Well, I have found out a few things about Serpentine belts and the various sizes a person can run. I bought a super cheap 950mm length, the absolute shortest belt for $12 on clearance at Rock Auto, Made in Mexico no name brand. After not tightening my top pulley🤬, I skinned my Continental 967mm belt that worked well. I ordered a 955mm Drive Right belt for a good price off Amazon. Under the Drive Right name. Just Made in Mexico and numbers, no name on it. While listening to the $12 belt squeak away and waiting for the replacement to come, I went and bought another Drive Right belt, this time 975mm, Dayco name and made in Italy, so far so good. Also the best price in the range that might fit. At 975mm it has the tensioner maxed out toward the A/C compressor. The 950mm was pretty much maxed out with the tensioner the other way. Interesting 25mm difference in length works with an auto tensioner.

Well, I took the 88 for a very long drive, 225 km there and back. It ran 210 at most, around 205 most the way. Oil pressure was 36 to 40 psi with 5W30 synthetic. It is a 47 year old bottom end, so about right. It used some oil maybe a 1/4 quart, thinking it was a bit over full. I plan on using a different stick, this one fits way too tight since removing and putting the tube back in. I have many, one goes in much better, just none the right length. Going by 4 quarts in the pan and will mark. Mileage was meh at 19 mpg imperial, but not taking it easy following our Challenger GT, 60 to 70+ mph. My speedo reads about 5 mph slow according to my GPS speedo app. I drained but left the filter, only 250km on the filter and put in 4 quarts of VR1 20W50 in, guessing that the level is right. I pulled the thermostat, 195 like I thought and put what I think is a Robert Shaw 180 high flow, no temp, just a number I can't find online. My other Robert Shaw says 160, so it must be the 180 I bought. Not that 210 degrees and 40 psi max hot oil pressure at lower rpm, 1800 to 2000ish is bad, about normal for every new LS I have driven. I just want it even a couple of degrees cooler and higher psi. The trans shifted great and leaked very little fluid. Around 20 mpg isn't what I hoped but 4 mpg better than my Dakota.

Well, I was lucky the belt didn't go flying off. It actually broke the middle bracket button head. I actually added a support up top from the alternator to the intake, so it is now very solid. It now runs around 175, it never got above 190 in the 70. Even if it hits 195 in the 88 it will be fine and still a touch cooler than it was.

It will hit 190 till the thermostat opens then 170 to 180, might be air or just the Robert Shaw high flow thermostat. Reinforcement seemed to fix the the noise and belt flopping around. This carb is super lean at idle and there may be some wear on the throttle shafts. I have had to crank the idle to over 1000 rpm in park. One minute it runs fine at 1000 rpm in park, next time, especially once warm, idles about 600 to 700 in park and needs gas not to stall once in gear. I put it around 1200 rpm which should not be necessary. I will probably open up the idle circuits and rebush the throttle shafts this winter. I will check for leaking well plugs as well, immediate hot restart usually requires flooring the pedal.
