Best Intake for a 408

The current cam is 241/247 @.050 with a lift of 545 and LSA of 115 but also at 9.0-1 compression. I had a suggestion of something around 260 duration and 600 lift with a 108 maybe even a 106 LSA.
Is that a modified Comp XE-HL? I had Comp modify my XE285HL to a 108.
Sorry for not being clear on what I’m looking for out of the car, I’m not sure I have a clear vision for what I want. It will be a hot street strip car. Yes I will race it, but not on a weekly basis. More like 4-6 times a year, but still want a fun street car.
No worries.
Correct, the backstory is based on the turbo setup.

However the current setup consists of the block, crank and rods at this point. Everything else will be changed from the prior so that’s not relevant, because it’s getting pistons, heads, cam & intake right? It will be a completely different engine.
Right! So, what are you looking at as far as pistons? Flat tops, small dome, hyper or forged? Where they sit in the bore is important. Zero deck, bellow or above.
It looks like you don’t actually have the rear gearing settled yet? Do you have the 3800 converter already?
Regardless of the gears (they are essentially the same) but a cam with 260°@.050” and a 3800 converter is really not the best match IMO. I’d go down a couple steps on the cam somewhere in the region of 250° or so, maybe 252° or 255° at the most with “that” tc and gearing.

I run 11.44@114 with a 410, 3500 TA tight and 4.10 gear. Air Gap w/750 DP, 246/[email protected]” solid roller w/TF heads all in a 3200lb deer meat freezer. I run around the street in the 2800-5500 rpm range, really only run it to 6200 at the track. There’s no need to run it up to redline on the street though.

The thing makes so much power in that rpm range and as I only do rolling acceleration runs on the street (as blowing the tires off is pointless) it digs and pulls hard.
I have a ported Victor I intend on swapping to some day. I’ll dial things in and hit the track for testing and tuning. Then I’ll see what my 60’,330, 1/8 1/4 and Mph is as compared to running the AG. I won’t be changing carbs, torque converters etc.
And if the times are better all around great. It’ll stay on. But if I loose 60’, 330’ etc I’ll put the AG back on and never look back. I’ve built for midrange power where I predominantly operate on the street.
The AG I predict will make more power in that range with my setup, will be a little quicker.
If you intend on going with a cam such as you mention and a single plane intake, I’d definitely step up in converter at a minimum.

On behalf of the group and the OP, I wanna say thanks for spelling out your combo. This is right about the idea in my head the OP was after. Quick, streetable and now easy to follow.

Stepping up on your example of a mid 11 combo, since it’s now a known, is easier than guessing.
