You mentioned that this will be a street cruiser / bruiser and driven to car shows. Not sure of what intake would be ideal, but I would focus on an intake that has great bottom and mid power/torque. That’s where the fun will be to be able to drive it routinely. I went down the rabbit hole of building a motor for max power and it was not ideal/fun for the street.

If running an automatic, make sure to get the right torque converter as well that works well for your needs.

Good luck and looking forward to hearing how it turns out.

what cam-heads? the forum members will come up with a HP/TORQUE number for us. JLM has the under-hood setup figured out. Ask him what air cleaner he used and then use any manifold you have that has the same height as the torker2. I agree with Gary H. None your manifolds will make your seat of the pants dyno feel any different. I just read an air cleaner article from 2002 Hot Rod. Marlan tested 7 different air cleaners on a 520 HP engine. The HP spread was 518-522. The drop base with a 2-1/2" filter made 522.

Ken mentions air filters. Maybe a bit off topic but some might find this of interest....

A very long time ago I had a 'experimental' Edelbrock cylinder head that was tested on David Vizard's flow bench.
I had the opportunity to have lunch with him then and found not only a nice fellow but pretty darn smart.
It was at that time I learned a bit about the K&N filters.

Take a few minites to watch this video starting at about 4.24 thru about 14.00

I believe what you hear will be very interesting.
Much more than they get more efficient when they get dirty !
Be patient and wait until the part about 'vibration'.

I've seen similar combos run in the 475-515 HP range. I have the same comp lobes in my 462 with 112 lsa and 108 isl.

I will agree 500 HP is about the limit for a stock intake. My first ported E head 455 259/264 SR I kept the HO intake until I found an extra Shaker base to "massage" for a Holley/Demon. After I found one swapping a Demon with an adapter for the worked Qjet at the track picked up 0.3 seconds. Swapped a Torker II on idled smoother and with jetting the car ran 10.90@123 in good air, 6.9 1/8 at 99 weighing 3750.

Yeah if I were really chasing power numbers I'd go with a good single plane every time, especially on a bigger inch motor. With Pontiacs and the 4.210-4.250 cranks they have absolutely no trouble making torque so sacrificing a pinch of that with a single plane really isn't a big deal anyway.

I'm hoping to reach the 500hp range. I'm going to use the street Dominator intake. It will be match ported with some Plenum work at 10.53 to1.

You will be fine. Well thought out build that will make more power than most builds.

Ok cool thank you!

Do you have a guess what it will most likely make?

[PAUL K]

If you are using a factory manifold without modifications it's going to have a hard time keeping up with some aftermarket manifolds on a true 500 horsepower build.

Truth! I can be done with a factory intake, but it'll take some work. And you're still limited to a spread bore style carburetor with the factory intake, unless you run an adapter, which I'm not a fan of.

I'm using a Holley Street dominator that is port matched with some plenum work..

My ported T2 and the Holley modified by SD I borrowed from Steve C were identical on the dyno with a square bore carb. A Qjet needs a spacer for the front runners to flow better because the carb pad is closer to the top of the runners.

The proper shape of the air cleaner base can add close to 6% more air flow over a crappy one as shown by these test done by David Vizard a number of years ago.

That's pretty good. I've taken a few out of the box untouched and made good power with them. One made 507hp on a very mild pump gas 455 with no porting. So they'll support what the OP is asking for without any work if the rest of the combo is well thought out.
