Holley EFI LS Hi-Ram Intake Manifold Bases
Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.

Nice!
Fit Type: 33" Inseam, Size: Medium, Color: White
Surprisingly nice. Fit is good and just a bit long. I expected shrinkage, however, after washing in cold water and drying warm, there is none that I could see. They wash nicely and don't need an iron, at least in the white version that I ordered.

Perfect material for comfort & offering different lengths for taller women!
Fit Type: 33" Inseam, Size: Medium, Color: Black
Great pants with different lengths. I love these pants& being 5”8 I wanted a longer length for wearing heels so the33 inch long works great. I plan on dry cleaning to keep them looking new! I now own 4 pairs & waiting for more colors to be available in the long length.

Great quality, a bit frumpy
Just ok. Probably should have returned these as I feel a bit like a grandma when I wear them, So they hang in my closet. Not super flattering but nice quality and fabric. Thickness is perfect. Style just isn’t for me but comfy

Amazing Fit For Tall Senior Slim Person!
Fit Type: 33" Inseam, Size: Medium, Color: Lake Green
I usually wear a size 8 or 10 or medium. But being 5 foot 11 and weigh 145, it’s very hard to find pants that fit. These in medium are great lightweight and long enough that they touch the floor in the back. Being older I have extra weight in my stomach and waist, but the waist is wide and not tight. It fits nice in the back also and the rise is long enough. Great summer pants for our hot weather in Florida. Even if they do pill some, I have a gadget that removes any pilling so not worried about that. I got the medium in the teal color which is not as bright but a nice color.
