Well after the next trip the Olds is getting pulled out? I have a shop that I?m taking it to already but would like some opinions since I?ve been waiting to have the motor done for almost 5 years. Things I know are done? bored 40 over, big valve C heads original from late 60s, air gap intake manifold, total hours as of right now 100 on it going to put a few more in October. What was told to me from original owner?. Bored 40 over rebuilt with a stroker kit?. So my question is I have roughly 5k to put it? already have 1900 towards new roller cam matched to my pump which is a AA aggressor, valve job, lifters and springs? what would y?all do with the rest? I run a edelbrock 800 carb? I?m going with roller rockers to already? should I go with higher compression pistons? I?m for sure going to listen what the builder says but would like to hear other opinions so I can ask the good questions. Right now I am spinning the AA to 5000rpm reliably?.and the pump is fresh with only 10 hours on it? I would like to gain anywhere from 500 to 700 rpm don?t know if that is too much to ask? well maybe we can start a thing that says ditch the olds sell it and put a BBC in it lol

Going off of the Olds article, Do you know what Olds oiling mods have been done?

Another thing from the article, is the divider between the center exhaust ports on the heads. It doesn?t meet flush with the header flange and has a gap from port to port. They fill it in and grind it to have a nice flat area for the exhaust to hook up to.

I don?t think he gets on here to much anymore, but 69 Kona had a pretty good running Olds. Maybe send a pm and see if you can pick his brain.

Thanks bud ? the new 461ish olds in our grape boat is high 80?s all motor .
Love helping out guys build their olds when I can .  Looks like you got him on the right track with the oiling stuff.

Have you figured out what changes/modifications are going to be made?

Are you planning on getting a larger oil pan?

Well what has been discussed is head work or go aluminum heads? going to go with a msd distributor? hydraulic roller cam, lifters, rockers?. Check compression leak down? modify oil pan for more capacity? may or may not change pistons? dyno tune it? and once dyno has a done have the impeller cut to match if needed. I let the builder know my budget and what I would like to get to? so we shall see what direction we go on heads either port what I currently have and update valves and stuff but may be cheaper to go aftermarket route.

Oh the pump was burnt out even though it was recently rebuilt? long story short is MPD has gone thru it and detailed it? my impeller that had only 25 total hours after rebuild was shot? so waiting on dyno sheet to cut new impeller to the motor? mpd also machine the diverter to mess with tuning nozzles? can?t wait to get it all back together.

I had the same issue with my pump from that shop I won?t name. Not trying to start fires here. I really don?t care anymore. Here is my story. Spent a large sum of money for an energizer pump. Towed my boat all the way up there. Left it. Drive all the way back to get it. I really liked the family and the job they did. First run, the pump was ruined. Didn?t even run the boat hard. My friend has his newborn baby on-board. When I called the shop I was accused of running the pump dry for the cause of failure. My option given was to pull it out, ship it to him, then go from there. Something didn?t seem right so I had a different shop go through it instead. Upon disassembly discovered that my pump didn?t have the AT energizer kit. It had his knock off parts in it and was assembled with tolerances too tight. Could only re-use the impeller shaft after one run. That?s it. Also, the transition inside the suction was horrendous Jacuzzi YJ. It wasn?t filled or smoothed at all.

Best of luck to you. My boat absolutely hauled ass after the pump was built right. Kind of funny regarding your Olds motor parts. If you need parts, shops and people charge top dollar. If you have parts, you practically have to give them away. I was never able to get my Olds to last. Went through 5 of them. I also was the guy that got your Hawaiian sold. It?s in a good home now. Has a new motor and lots of work done. My co worker bought it.
