Intake Question
 

I'm contemplating changing the intake on my car. Here's the overview of my engine/car package.

402 +.040=410ci, 10,5:1 compression, solid roller cam (.640/.647 lift, .236/.242 [email protected], 110 LS), Muncie M22W (2.52 first gear), 4.56 rear. The car weighs 3800 lbs with me in it. I shift the car at 7000 rpm.

I have been running an Edelbrock TM2R intake with a Holley 950 HP carb for a few years now. I have an over the counter 3933163 intake I could modify to work with my motor. I've had people tell me to change it to the 163 intake because I need the dual plane for low end torque and that if I cut the plenum down similar to a 198 intake, it will work fine at 7k rpm. I've also had others tell me to leave the TM2R on for the rpms.

Keep in mind that I know there are better intakes out there like an Edelbrock Air Gap but I want to keep it old school.

Any opinions?

Thanks, Kurt

my vote is put the 163 on.

I say leave her Old School, she runs Great!.....But if you must....try and see how you like the 163.....you can always change it back.

You can try the 163 but the Edelbrock will out perform it in your situation.

Sounds like a pretty balanced setup. The compression is a little low w 110LC as 'effective' compession suffers with that cam. I think a little smaller 800cfm may get you a little better ET IMO only.

I had a 850 dp on it, made 3 passes at the drag strip, pulled the 950 HP out of the box and dropped my ET by .015. This motor loves RPMS and fuel.

It would probably be better to run a smaller carb on the street but it's too much hassle.....I'm lazy!

Re: Intake Question
 

If your 950 is an older unit, it's actually smaller (cfm-wise) than the 850.

The 80496 has a 1.375&quot; venturi and a 1.750&quot; throttle bore.

A 4781 has a 1.5625&quot; throttle bore and a 1.750&quot; throttle bore.

I have a 163 intake with the Plenum divider already cut down if you want to try it first BEFORE you cut a virgin one...

There you go!

Keep the TM2. Those just look great. Old school.
