Holley Stealth Ram Custom Plenum
Guys, what would you be willing to pay for a Custom HSR plenum that would bolt onto the HSR intake and fit under the hood, just like it does normally out of the box?
or what would you pay to alter the plenum that comes with the HSR so it would fit?
Just a thought.

Unless the base can be purchased alone, altering the HSR plenum might make more sense, right? Consider polished option too.
Obviously, the lower you can do it, the more take'ers you'll have!
Do an LTx option too!
DO IT!

I don't know what the LT-X option entails, if the Holley has an intake base that will fit under the plenum, then well,, the plenum is the easy part.
I honestly don't think there is enough interest for me to make this a full production effort.
Once I get my engine back into the car which should take another 3-4 weeks, I will order some flat stock and make 1 or 2 of the L98 plenums,,, one for me and one to sell.
Since I have my current plenum for a template, I think I can make one now with the thickness of aluminum that will make this rigid and a very nice looking piece, able to be polished or chrome plated, or anodized etc..
I looked at 6061 aluminum prices and the cost for the Aluminum alone is @ $85.00,,,,,,, and I am guessing that I could cut, machine, weld and finish the plenum in @ 20 hours +/-.
Once I get started I will take pics, beginning to end, and then show the end result.

I will plan this out but it wont happen before the end of summer, probably will make a couple of the custom Aluminum plenums and take the out of the box HSR plenums on trade and then lower them like mine. So all in all, there could be 4 HSR L98 plenums available by fall, and MAYBE, on or two could be for the LTX cars but I have no dimensional info for this at all.
My engine is in 1000 pieces right now so it will take the next several weekends to reassemble it, then several weekends after that to recover and drive it.
Plan on driving the Hot Rod Power Tour this year, one way or another.
