What do those relays do?

High beam and low beam for my headlight harness

The kooks headers are 1 5/8 primaries to 2.5” exits??

Correct.

I know primary size has an affect on low end torque/ top end power.

What are your power goals with this build??

Based on similar combos it should be good for somewhere between 340-360rwhp once I get it all dialed in

 

[Chingon1]

can you run down your combo real quick??

Db heads?
Mach 1 intake?

Is anything ported??

It’s a full Mach 1 spec engine, intake, 03 C heads etc. no porting though I might have the intake worked on eventually.

I was amazed by how much bs was left by the factory.I matched the gasket to the heads, then matched the intake to the gasket, and got rid of the crap left from the factory machining.

That’s a pretty sweet build!those intake definitely could use some help. They really run out of steam up top. Here’s a post from a guy in a FB forum that ports the machs. First one is a simple port job, it really wakes it up up top. Send link is his 6” runner which look wicked cool. Pretty sure killing low end but with cams it should make a pretty cool high RPM screamer.

When I got the cams I reached out to Todd Warren to find where he thought would be a good spot to degree them to, including throwing out the thought of going ported/ short runner with the intake since I figured I’m running 4.30s and sacrificing some low end wouldn’t be a huge deal, but he staunchly recommended against it regardless.
