Hi Tech just purchased a LS-7 intake to try with this combo. Should have more results by Monday.. Hopes are that the intake makes the power of the sheetmetal and the torque of the L-76 intake.

I didn't think LS7 and L92 were that different? and I didn't think the Ls7 fits on the L92 heads?

Give me a call, ya meat

Trail 70 so when are we planning to put the motor back in the car. My time is limited, when do want me to come over and put it back in your car for you. Make sure you get that hanes manual. Oh by the way if you want you car to go faster try a body weight reduction. (not the car)

The intakes ARE different..... I would expect an LS7 intake to carry power much better than the L76 intake, BUT, you are correct..... LS7 intake will NOT fit on L92 heads. Port shape is slightly different and more importantly, bolt location is different.

I'm a tech for Honda during the week and it's hard to get motivated to work on cars on the weekend. I should get off my lazy *** and finish it in the next couple weeks. I will have 2 different chassis dyno numbers..

I would love to see the pics of the heads and manifold. I've been playing with the idea of epoxying the floor of these heads for a better SSR and reducing the CSA, and putting them on a 375ci Iron block.

Do you believe the stainless screws really work well as an anchor, or did you just do it thinking "eh, shouldn't hurt". Thanks.

Default intake difference

Has anyone heard about the differences of the l76 and LS7 intake?

I'm getting ready to purchase one, and I wanted to know which was best!

Subscribing!

There are many differences. It depends on what heads you have as to which one you can use.

Default more info

My bad.....

2002 6.0 liter, going to L92 heads. I'm putting this into a truck, so hood clearance isn't a problem, just wondering should I purchase a L76 intake.

Here, I'll start a new thread, not hyjacking......

Thanks

Moss

ps.....GREAT work on the 700hp!

He's been too busy playing with his matchbox cars

OK did i miss a link here to your dyno graphs?
I am a avid user of epoxy to allow port sizing and shape changes, surface prep(cleaning) is #1 key to success and reliable epoxy use.
I am extremeli interested in what your #'s were above 6900 cause mi L92 402"
goes into seat bounce hysterics at 7000 rpm with similar sized Comp hydraulic roller and #26921 springs. I run a GMPP carbed intake and mi peak power is at 6900 so i have no room to shift past peak(a real problem with TH400 auto)
What valves and springs does this set up have and how high does it rev cleanly? TIA
