Best Intake for a 408

rumblefish360 said

In your case and if the cam is the same, super close, slightly larger, I’d run a very ported Weiand. It’s a small single plane designed a long time ago when stock heads were the only option unless you went with a W2. The big cubes will tax the small plenum and runner sizes quickly.

At 420 cubes, I’d prefer a Super Victor or a Tunnel Ram.

Rumble,

My cam is currently spec’d out as a 248/252 @ .050”, .410” lobe solid roller. Max rpms will be in the 6200 range.

I looked at the Super Victor and assumed that it was too much (maybe too tall) for a street ride. That is why I decided to start working on the two intakes that I had on the shelf. I was also looking at the TF Track Heat but since the deliveries are unknown and I also thought that it might be a little too big. So, I thought that the X-celerator (gasket matched) might be the first one to try. The pictures that I posted above are the X-celerator before I got started. I was surprised by how much aluminum came out of that intake to clean up the areas shown in the pictures.



I don’t want to take away from this thread, but once I get my block back from the machine shop jail, I will start a new thread on a couple of items that I have not tied down.



Thank you!
