Overview:

The new single plane EFI (Electronic Fuel Injection) intake manifold is designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style 112-587 and 112-588. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features; like an updated plenum divider area, a 1" shorter overall height than most single plane manifolds, and a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase charge air density and performance. The fuel injector bores have back-cut exits in the runners for better fuel atomization. This design points the injectors at an angle to match the intake runner airflow angle. The black coated fuel rails and rail bracket assortment are included with the manifold for any easy installation with the injectors that you choose to use for your combination. Fuel rail designed for maximum throttle lever clearance. Its low profile and single plane design are ideal for Sniper / Terminator TBI installations (dual planes aren't ideal for EFI) Vortec Intake fits most popular GM crate engines equipped with Vortec or Fast Burn Heads including HO engines (like 350 HO), SP Series Engines (SP 350) and ZZ Series Engines (ZZ6).

Features:

  • Single plane design with isolated plenum to keep the air charge cooler
  • 4150 square bore mounting flange to adapt most aftermarket throttle body designs
  • Power band: 2500-7500 RPM
  • Height: Front 4.23", Rear 5.33"
  • Port Size: 2.05” height 1.02" width

  • Fuel injectors are not included
  • Fuel rail designed for maximum throttle lever clearance
  • Small Block Chevrolet 262-400 cid engines equipped with 1996-2002 (L31) Vortec cylinder heads (non-EGR applications)

Glad I Gave It a Try
Flavor Name: Orange, Size: 15 Ounce (Pack of 1), Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
I wasn't sure if this Metamucil fiber supplement would make much of a difference, but after taking it consistently, I'm really glad I decided to try it. The results weren't instant, but over time I noticed that I felt lighter, cleaner, and just generally better overall. The sugar-free formula is a nice bonus, and it's easy to make part of a daily routine. I've found that consistency is key, and once I started taking it regularly, I could definitely tell a difference. If you're on the fence about trying a fiber supplement, this one has worked very well for me. It's a simple addition to my day that has had a noticeable positive impact. I'll definitely keep using it.

It works.
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
It really does help 'keep you regular' & the name brand dissolves easier than the generic W@lm@rt brand. It doesn't MAKE you 'go', it just gives your gut a little something to work with, so to speak. Maybe TMI, but you also go alot cleaner, if you catch my drift. That's a nice bonus. ;0)

Great to curb food cravings
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Saw this on a YouTube video for reducing appetite/curbing snack cravings and wow! I’m on day 2 and this will always be in my pantry. After 30 min of drinking this I feel sooo full. No appetite for 4 hours like I ate a huge meal. The flavor is also good. No cramps or gas and the fiber content isn’t crazy so I haven’t experienced any negative side effects either. If you’re trying to lose weight this may help. Haven’t thought about snacking all day. Give it a try

Great for my tidy mind. Now the cabinet is organized and clean. Space saving too
Size: Left Facing, Size: Left Facing
Easy install. Glides nicely holds the jars without much movement. The labels are wonderful. I am super pleased. We bought 4 left facing for our cabinet. Not done replacing all the jars and such. But you can see a good idea how it will be. The fit out needs perfectly and looks great. I really like how neat and good visibility too. They seem sturdy with all the weight of the filled bottles also.
