3", that's all that fits under my hatch, I did however gut them....

No, the time was not there or the parts... My Dyno session was simply to see if engines match and very little tuning...

I do believe I saw somewhere,one of the car mags did a test w/ a little 350,,dom actually worked,made power and they did have to jet down a chit ton.but it did work.

thinking plan, fix trans, I have forward still but no reverse, do not wanna run that way.... my buddy can fix in a couple days of dropping off...

go test boat, vacuum gage, also remove arrestor, hoping I can get this figured out before winter....that's the goal I think...

I'd also set a baseline by running with the hatch off so if you do find a set of dominators to try you are comparing apples to apples.

I agree there! My engines have stock dampeners and that is the next thing to go. They will be replaced with ATI's.

I did that last winter. Well, not with ATI, but replaced the stockers, with Powerbond SS race balancers. One of the things that concerned me, was being that I had a external balance setup, was the weight match of the balancers. I called a few shops, including the one that balanced my rotators few years back, and they said they don't balance a damper. Some acted like I was talking crazy.

I finally found a local shop, that I never even knew existed. They do in house crank work, heck, just about everything in house. Anyways, I called the old timer, explained what I was doing, he said sure, no problem. Bring the old ones in, and the new ones, and we can certainly check them against each other. He spun them, checked them, and they were a C hair away from the old balancers. No actual work was needed. Got some fancy computer printouts of the balancing tests. Cost me 150 bucks to find that out, but, I felt better about installing them.

I didn't feel very confident spinning the stock old GM balancers to 6000+. I heard good things about the powerbond units from a few marine engine builders, and Icdedppl's 540's have had them on there for a while now, with blowers and good results. They make them in a supercharged version, with double keyways as well.

I thought so too. I basically wanted to ditch the 30 year old stock iron/rubber units, with a steel unit. ATI's are great balancers, but knowing that sooner or later, I'm going to outgrow these ext balanced 468's, I didn't feel like dropping 700 bucks on a pair of balancers.
