Back when I was on the stock trans I made peak at 8k and fell at 8400. That was when I was still on n1 cams

The k24's ive seen running seem like they use a long 1st, very short 2nd and 3rd then a long 4th.

I think thats what roccos car needs. Cory's car was making peak at what 8700 or so and holding to 9200 without falling miserably.

Its just down to setting up the trans and slick size for each individual setup. Personally the 23's would be a better option because they allow more traction and more "spring" off the line if you preload it right.

What slicks were you running in that last vid cory? looks like 23's but on a 15" wheel.

What are you crossing the line in 4th at?

With a big motor the power fall off much faster.

Nope not yet. Although I have tested a 2.25 choke on the new header and did loose power.

So what choke did the new header come with?

Saw this on ebay, comes with a 2.65 collector. Also, would rather see a nice transition after it or reverse cone, but there was a seller getting rid of them for $300 shipped, so I'm kind of debating on grabbing one just to try out against my budget header just for fun. Looks like it might not have to be modified more than just the head flange.

From what ive read reverse flanges only work with open headers, theres no gains with a reverse cone volted to a full exhaust

Damn for that price its worth a shot. I'm sure it will take some modification but looks good.
