Thank's TURP! I am trying not to be bummed out with the progress, but, it kind of has hit a wall!

[swyfor5]

Thank's to you too Jaro! Don't really know what way to to go with the carburetor setup.

Just ordered up a new Hayes H.D. clutch kit. Researching flywheels now. Not sure what flywheel I need to swap in the 383 stroker to my 465 manual transmission?

[swyfor5]

Got a Hayes super brute 12" clutch kit p/n 490-90-102 coming from JEGS. After researching the flywheel needed for the 383 swap, I just ordered a SBC400 flywheel for the manual transmission with external weights p/n FW102 from Northern auto parts. Hope this will be the right combo? I am really in the dark here, anybody got any thoughts on this swap?

[swyfor5]

HELP! Anybody else done this swap? Any advice would be great!

[drunkbus]

No help here, but kind of an interesting story. My Dad is friends with Bill Hayes, the original owner of Hayes clutches. Neat old guy. He sold off Hayes clutches long ago to some other company then founded Centerforce Clutches which his kids run now. He's in his 80's but still tinkering and inventing new stuff. A little off subject but a little history for you on Hayes clutches.

Cool story DB! Got the hayes clutch kit today, looks real nice. Flywheel should be here tommmorrow. Anybody else running a 383 stroker with a 465 manual trans?

[swyfor5]

Allright, I have come to a crossroads on this 383 buildup. It is not top priority right now, just trying to figure out what I need to do. Got the clutch kit today as stated, and new flywheel tommorrow. After doing research on 383 motors, I am going to have this entire motor tore down before buying any more parts. The "friend" I bought it from failed to provide any build documents, so I really do not know what has been done. I need to determine what I actually have here, and what it will take to balance everything right! When motor was pulled from his corvette, it ran good but had some top end noise problems. Sounds like it was not set up right in the first place. Might as well start from the machine shop and do it right this time! Gonna get with my partner from work and start to dissect this stroker!

[swyfor5]

Well I just ordered up a engine stand so I can pull the pan off. Get the numbers off the crankshaft so I can ID it. That will tell me what Scat crank it is, and I can go from there. Sounds like a plan to me?

[swyfor5]

Engine stand came today! Now I just have to put it together. Thinking about getting a cherry picker next to aid in moving the motor, and swapping them around.

[ERASER5]

Most 383 cranks are externally balanced. So the 400SBC is likely the right choice. Internally balanced 383 cranks are VERY expensive due to the Mallory metal needed. Would your "friend" have fliped for the extra coin?

[swyfor5]

That's my problem, can't get much info from him to verify what he actually bought for a stroker kit. So far all I have to go on is the front harmonic balancer on it looks just like the standard ones on a 350. He was running a auto trans in the vette it came out of, and I am running the 465 4 speed trans. I can't find the flexplate off it that he gave me to ID any weights or lack of on it. Just don't know what I did with it?

[swyfor5]

Well I think I just solved my balance mystery. I went out and really looked at the harmonic balancer. It has a weight with two holes in it mounted on the inside. Did a search and found pic's of Summit's P/N NAL-12498008 balancer for a internally balanced 383. Looks just like the weights on the back side of the one on my stroker. I guess that means thats good news and bad news. The good is my friend sprung for the better 383 stroker crank kit. Gives me a better crank, and I understand should be the 1-piece rear main seal. The bad is I bought the wrong flywheel and need to find the right one. I do feel better now, knowing I have the internal balance setup! Any feedback?

[swyfor5]

After more study, I am not so sure here. Can sombody help me out here? Not being stupid, but this has to be right on. Would like some help here?

[swyfor5]

Allright! I finally found the flexplate that came with the 383. No weights on it at all! That with the ID on the harmonic balancer tells me that it is a internally balanced scat crankshaft. Flexplate has 168 teeth on it. Now I just need to find the right flywheel to fit my 12" Hays clutch kit. Getting there!

[swyfor5]

Well, as usual I am clueless. Weather is starting to break here so I can get the new engine stand set up in the pole barn soon. Already had the new externally balanced pioneer flywheel here, and ordered up a Hays P/N 10-130 internally balanced flywheel. Just trying to make sure I have what I need when I make the swap.Planning on still pulling this 383 apart top and bottom to ID it.Really hoping it's internally balanced as the Hays flywheel is S.F.I certified. Hays flywheel came today, Summit Racing has fast shipping! Need to tear the oil pan off this 383 and make sure what is actually in there!Weather gets better here and I will post up some new pic's!

Spring fever has set in here. It was 70 today!

[swyfor5]

I wish, 1 and 1/2 inches of fresh snow here this morning! Won't be long though!

[swyfor5]

Weather is getting better here. Snow and ice almost all gone in front of pole barn door! John has been in the shop lately, so it won't be long before I fire the K5 up and get going!

[swyfor5]

Caught John at the CHAOS shop this afternoon. He is off work for a little while and making some progress on stuff! Gonna get my steering knuckles reblasted tommorrow and start finishing the assembly! Should be able to get the K5 up there real soon and get up to 1 ton status! Can't wait!

[swyfor5]

Anybody got some pic's of the seals for the top to bedside seals?Double wall vs single wall would be great. Double wall top here, but single wall pic's would help also. Bought a set from a member here, and just want to make sure they are for a double wall top. These came from Brothers P/N 617618. Mine never had any seals there when I removed the top way back once, so I used a 1 sided sticky 1/4" thick x 1" wide rv tape. Didn't really work ! I want it right the next time I do it. Thank's!

[swyfor5]

Ok, a glimmer of hope today!I caught John at the CHAOS shop today. Had a good chat about what's going on and my project. He is layed off from work now, and looking at renovating the shop. The weather is getting better here and looking at doing some additions to the shop. All the ice and snow are finally melted from in front of my pole barn door so I can get the K5 out. He has my front disc brake brackets painted and ready to go. Also had my front steering knuckles reblasted and primered up. Still going to paint them chevy orange again, this time with the right paint. Working on cleaning out the shop again to get my K5 in there. Can't wait man! Plan on actually getting some progress done on this project soon. John said he is willing to give me a key to the shop so I can go in and wrench when he is not around. I cannot wait to get going on this and finally get these 1 ton axles under this K5 and drive it again!
