Mushroom Cams?

[67charger383]

Anyone have experience with mushroom cams?

Butter, salt and pepper...… yum

I have one for next build. A NOS Direct Connection Mini Express.
A good friend has one like mine (.654 lift) in his Challenger and the larger version (.690 lift) in a Cuda. Both sound and run great !

Definitely old school stuff.
Newer custom grinds are better. Camshaft tech has come a long ways.

Get ready for the nay sayers.........

As an alternative, I offer the following:
1. Lightly sauteed and stuffed with crab meat then broiled, served with an ice cold Fat Tire in a frosted mug
2. Sliced thinly then beer battered and deep fried to a light golden brown
3. Thinly sliced and sauteed with peppers, onions and shaved beef and served on a hogie bun with Provolone cheese....a la Philly Steak Sandwich
4. On a Sicilian thick crust pizza with onions, pepperoni, and extra cheese, maybe sausage and green peppers
Just a few favourites....

Ive heard of the mini express .654 cam
Would one work for my application and be "streetable" with E85?
(12-1 compression 30 over 383 with 915 heads, a gear drive and a tunnel ram)

And also was the Mini Express a 3 bolt cam? I need one to work with a Milodon gear drive.

Yes it is a 3 bolt cam.

It is relative to what your definition of street able is - yea you could drive it.

I have driven several street cars with solid lifters over .600 lift and solid rollers with over .700 lift.
Probably not practical but can be done.

Would I have ridiculous detonation problems with .640 lift and 12-1 compression? I should be good with E85, but I'm still learning as this is my first engine build and I'm doing it myself.

 

[toolmanmike]

mushroom cams or mushroom lifters?

mushroom cams or mushroom lifters?

Both, and for cams I'm kinda leaning towards the DC Mini Express cam, but I also am thinking about Racer Brown mushroom grinds.

Haven't heard about those for decades. If I remember, the block needs to be surfaced on the underside of the lifter bores for the lifters to work.

I had a mini express. It went flat but it wasn't the cams fault, I didn't know what I was doing. Bad breakin, I couldn't get it started right away, and I used WAY too much spring pressure for breakin. I wish I had another. But, that is a BIG cam for a 383, even with 12 to one. It will certainly stop any detonation problem with E85.
You might even get away with pump gas mixed with 110, or avgas, depending on cylinder pressure.

I had my block done just that way, a spot face at the bottom of the lifter bore for the mushroom lifter. Totally unnecessary. There was plenty of clearance without the spot face, maybe .200

So you think a mini express would work ok for me?

Just in a Cummins

I don't think I would try that cam for a first engine build. It would require some razor sharp tuning for street use. I would try it if I was an experienced builder with lots of familiarity with the e85, which I definitely am not. You will need a specific e85 carb, good tuning skills, an alcohol compatible tank and lines, pump and fuel filters. A GIANT cam added into the bargain is a lot to put on the table.

Not worried about the fuel system, its all getting replaced with E85 stuff anyway.
And tuning will be easy because I have a Programmable MSD 6al2 box

Let me know If you aren't using it because I'm interested and would buy it.

My mushroom remains my favorite cam. I'll PM you.

Mine didn't on each of the 440 blocks or the 400 blocks I used it in, plenty of clearance.
