I'm not going to get all technical into why I agree Proppy and GT are right on all this. PM me if you want that whole storm. lol.
Leave it at this, T/R's in general are very high rpm only devices that require a TON of compression, Cam, fuel (Both pressure and volume), and forethought into their setup. Not many of these things are very conducive to the Oldsmobile engine, I'm sorry to say.
Vacuum secondary vs mechanical, I run vac, and run inline because I beleive there's inherent bank to bank rich/lean conditions running larger carbs sideways unless you run 1:1 as Proppy does (Firing order comes into play........its a LONG thought process and reasoning behind this).
There's an inherent hate for vac secy's here that really is unfounded, even on T/R's. Trick is spring selection, and that's probably the ONLY info you will gather with a Vacuum Guage that might help with that. Other than that, a Vac guage I don't see doing much for you that a can of WD40 can't in checking for leaks. I did it through trial and error, and the weird setup I have. I duplicated this so my "ship" will have twin setups the same way on 2 engines and jets! Thanks to Proppy and Jim Brock I was able to replicate that arrangement.
The only real insight as to how a T/R is working and to tune it is throttle response, reading your plugs, and performance. You will do this MANY times setting one up right. 2 of those are seat of the pants measurements, only 1 a technical measurement, if you notice. Yes, on a jet boat, pump setup will have a LOT to do with it, just as in a drag car, gearing and tranny issues are involved as well.
Single 4 BBL Tunnel Rams, regardless of what engine and carb on them, IMHO and don't take this the wrong way, are like watching someone else get laid. You get an insight as to what it's all about, you get to be in the room for the show, but you don't get to experience the actual thrill of it for yourself!
Stick with what works on the Olds. A good hi-rise single plane, large carb, cam and compression to work with it, then the pump must match that. I also have a Jacuzzi/Olds combo that will be going through some "changes" over the winter (Among other projects going on). It will stay Jacuzzi/Olds, but as far as where it will end up? A very decent and reliable Hot Rod, but probably nowhere near as fast as others I have laying around.

) and Marcsrollin is keepin it all to himself at his shop in El Cajon........J/K Marc!.........yes, Rotella diesel oil is used a LOT in breaking in engines. In point of fact, its what my diesel pickup uses day to day. Diesels are NOT Hot Rod engines, however.
