At that time, the lake was down like 30 feet or something. I left and that lake has been at or over full pool since then. Ridiculous. Have 2 good friends on the lake on the Dawsonville side. Was just up there for Petit Lemans at Road Atlanta. That lake is a good time!

Yep, we are on Dawsonville side, just off 53 and West of Little Hall park.
Last boat was slipped at GM but current boat is too clean to keep in the water. Garage is going up next month to store and work on the boat and I will be a trailer sailor for the foreseeable future. lol

Yeah... it really is a more rugged/robust engine compared to all the previous generations. I will be keeping the platform alive in my boat.

PSI main bolts are an odd thread count. They are metric but they are 1.5 rather than 1.75.

improvement over stock.

I have 6 new arrivals of psi blocks and Kellogg crankshafts.

I guess we are keeping OEM bolts down there instead of studding it...
Which brings to mind something said to me years ago by friend and fellow drag racer... Andy Jensen. Google his name if not familiar with him.

I had a brand new 4.500" 9.8 Merlin block in his shop to build a 555 for my brothers 69 Chevelle...
When i asked him about studding the mains and skimming thru the bores with a line-hone... he said: "Arty... you only WISH this motor made enough horsepower to need studs... the bolts are more than adequate."

So we left the bolts in there.

Here is a quick little clip from the show "Pass Time" in 2009 where my brother and I had our 2minutes of fame. This was one of my last trips down the 1320 before hanging up my helmet for good. lol:

Do you know if the cam sensor from a 24x 8.1 will read a 58x reluctor ring on the PSI crank ? or do I need to swap over to the 24x reluctor ?

you need to change the ring to 24 unless you are changing the ecu.

That was on my mind also.
In the LS world the OEM ECM is tied to the 24X or the 58X, so regardless if it does your Volvo ECM may not be compatible.

He can change the reluctor ring. Several guys have changed them after issues with the trigger.

Yes sir. Seems he'll need to.
He just seemed to be hung up on the sensor.
My post was in regards to even if the senor does it's moot because the Volvo ECM may very well not be compatible.
