Talk about a cluster ###. I put on the 4 hole adapter but it just isn't right

At least the aluminum would pull some weight, run cooler and hopefully flow slightly better. The big benifit I see is getting rid of that stupid 4 hole entry of
the manifold.

I just don't have the experiance with these bow tie engines yet. I need to pick
some brains that have that experiance.

well sorry i can not tell you what you want to heari have been building bbc for 30 years from 396to632+ and was a merc tech. that carb will not know about the 4 hole spacer it going to work long as its not sucking vacuum . your going to have the cool look with a alum intake but and you could pick up some hp but to turn that in to MPH on the water would take more then a intake change to make it worth the money and time. stuff a blower on it now then you will have some thing

I'm not after a race engine, that would be like putting wings on a buffalo.

I just wanted an efficient set up that would yield the best power from this
package.

It's a cabin cruiser, it won't go fast till it's going over niagra falls.

It's really funny after taking our jet boat out to run the barge up the lake

But then again, we don't laugh when we spend the night in the barge.

Everything has it's porpose and within that is it's value

I really appreciate your input, do you think the weiand peanut port intake would then be the best intake for this package?

I'm going to change the intake, I just can't bear the thought of that scrap
iron sitting on the engine.

That was the only aftermarket peanut port intake I found. Do you know of any others in the power band of 0-5000?

I had an original edelbrock torker on my 460 back in the late 70's. It worked very well with the nearly stock engine.

To bad they don't make that one any more.

What do you think?
