Yep a 455 punched .030 (462) solid lifter cam allunium rods lots of porting to the heads trick oil system 11.1 to 1 compression about 600 hp pushed my 74 bird to 11:50s at 118mph not a bad ride in the 80s.but to much work it was like a second job

No wonder I like you! I ran a 58 Corvette back in the 60's, C/Gas and ran on the National record at New England Drag way, Sanford ME. 10.20000
Like you, when the fun came abruptly to a halt when they started bracket racing, kind of took all of the fun out of it. I had a 1959 F150 with a tricked 460 cu inch engine that we could have had fun racing. "LittleFoot' would scat too!

OK after running the boat this weekend and looking at new boats my old Larson is going to make the season.Sat I did a cruise around Long Island and today I took a cruise up to Moultonborough bay Poplar Island to see the eagles.The boat ran fine and as long as I don't look at the oil pressure gage I would never know it is a little low.I am getting about 25psi at 3000 rpm and about 6psi idle with no lifter noise.

Bob, If you now have the oil pressure you stated you should have nothing to worry about for this season. APS's suggestion of Mobil 1 and Slick 50 were excellent. Just keep and eye out to make sure the crankcase is full before each trip out on the lake. I also know that you never have beat on your boat so abuse was never a concern.

I would have to say that if you ran that vette you must know some of the same racers I do. Doug Jounis must come right to the forefront as he also ran a corvette in that time frame. How about Phil Miller, Smiley Smullens, Ray Blake, Art Gallent, Bill Douglas and I am sure that you can name a few others. Also Sunset Bob you should a good oil in that engine that still has a high concentrate of Zinc and Phosporus. Brad Penn SAE 40 or SAE 50 would do the trick as you are more concerned with oil pressure and protection then gas mileage. You did mention that the oil pressure drops after a hard run which would suggest that it may be a temperature related problem. As oil increases in temp it thins and builds less pressure. Could it be an oil cooler that is losing its ability to cool the oil. That coupled with wear on the engine over the years could be causing the problem. Just a thought.

And don't forget Ron Keenan (Mr Boston TF) Billy Pike, Dick Ingalls oh the list is long. They all helped me get started, as well as Tony Grasso
