78 TA with LS3/Holley TBI - Shaker scoop mounting

[Panteracer]

Greg,
I bought the original Blockers popsicle stye and it was junk
It did not even fit right under the shaker.. looks like what
you are looking at is a lot better

I ended up doing something like Byan cutting a bottom plate
to fit where the whole wants to be.. my car has a dominator
based carb with 4150 bowls for 1050 or 1150 cfm on the
CV1 manifold so it is really big and set far forward

I then grafted the shaker over the top by gluing oak pieces
up in it and then put threaded rods thru my home made
assembly (see attached pic of air filter)... air filter is a 3"
round that I made into an oval.. hard to describe but it works

I recently changed the Trans in my car and also the trans
mount so the motor is at 2.9 degrees down vs almost 5 before
and the front slightly hits my hood.. need to trim it a little

I can pull things apart to show you if you want more info
but looks like the Butler thing may work for you

Going to be watching this as, one day, I may switch my intake out so I can do this as well. Good luck, Greg.

Thanks Bob! If you have time and inclination to take more detailed pictures, I would love to see them! I know we are all busy too, so it's not a big deal.

What diameter is your round filter - I'm guessing that you don't feel like the filter area is choking your flow?

I'm leaning on fabbing my own plate - blockers/WFO style such that my shaker can fit onto it with the stainless ring and then use a rectangular KN filter fitted into the shaker itself. When I make the plate I can adjust for tilt and off center. I'm concerned that with the Victor Jr. style intake I have that I'll run out of height- so the rectangular filter appeals to me.

Greg, interesting data point here. When I dynoed a couple of weeks ago, we did so both with and without my current round filter installed. We removed it after a few pulls since we noticed vacuum in the manifold and wanted to see if it was the filter. It made very little difference. So we did the tuning without it installed and then reinstalled for one last pull. We lost 6HP when reinstalled, but it was also heat soaked, so to me it was little to no loss.

The filter I'm using is a 9 3/4" round 3" tall K&N at the moment just to give you an idea...

I look forward to seeing what you come up with. Keep us posted. I'll get back on my own setup here soon...

I also have a 3"x10" filter
I did cut the lower edging all the way around as my
CV-1 manifold is really tall. Not the best but better than
running a filter exposed thru the hole. I did that for a while

Greg,

You also have the advantage of a bigger shaker than Bob and I do. The later 2nd gen shakers have a steeper front edge which may help you out also...

In addition to the Dude Scoop that PTFB makes/sells, he also has a conical filter that may possibly work for you (I'm considering it also). He seems to have a shorter and a taller version of it. If you can get a drop base that it will sit in and clear, and your shaker will sit down over it, then I think that's a good option. With the bigger shaker scoop you have, it might work for you.

The one concern would be the shift to the side. Hard to tell how close the conical filter would be to the hood / shaker if your engine is offset that much.

Just one more think I'm also considering.

Definitely some good ideas here. I've been trying to figure out how I'm going to do mine with my LS3 intake.

What explains the vacuum in the manifold if the restriction isn't the filter. I have been also wondering about the opening size of the shaker scoops. In Bob's case I don't think that's an issue because it's open all the way around. If the only air is coming through that opening, does that choke the flow?
