Default 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.

$787.54 for the whole thing + shipping
$393.77 for just the modified plenum + shipping

Don't ask us! You already know the prices for the competitive intakes.

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 would only be interested in the LT4 style intakes.

Yeah, i've been keeping up with that thread. A y body actually has more room for the intake than an f body. I believe they only have something like 2 inches from where the stocker sits.

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.

As long as you can price it competitively with the others, people will buy it.

How about a plain steel ( or sheet metal ) version for those of us more interested in performance than looks?
Could always be power coated.

Just a heavier piece is all!

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.
