Nice effort. Mike is a pretty talented dude. He's built nearly everything in the car himself. Guys like him and Marcella seem to have a drive to go way above and beyond. I wish I had that drive. But, no time for that.

We had a 2.250" intake and a 1.800" exhaust in our heads with stock valve location. Very close together. So much so that on nitro and at high RPM's due to the large stem to guide clearance required, they hit each other. We reduced the exhaust head diameter and increased the stem diameter to 3/8". Problem solved. Normally aspirated, 2.250/1.80 would work OK even with a 5/16" intake stem, but I wouldn't build a max effort engine with those sizes. I would think a larger intake and slightly smaller exhaust would be a better choice, which is probably what Mike chose. Good luck on the dyno.

Stop it. You're making me blush.

Exhaust valve size is critical in n/a engine as well. Pumping losses and camshaft compromise shows up fast in n/a engine ... can't mask it. Exhaust is equally important as intake in n/a.

Is it the throat diameter and what ratio do you like to see (int/exh) for a 9,000 to 10,000 rpm 500+ cube engine? I know this may be something you don't want to disclose, but need to ask. I'm wanting to know for my heads.

I know its a balancing act but how much do you give the exhaust valve and take away from the intake? Signs that you've tipped the scales too far one??

Man Chris I'd like to hear a few more bars hummed on this topic. I've always thought cracking the EVO a little sooner fix the issue driving the focus on intake port/valve size.

And Alrighty then what do we have left....
Intake manifold. So again this is an area where a lot of guys just don't get it. They want a big hp engine and their uterus falls out when someone quotes them $1500 to port an intake. NEWSFLASH $1500 isn't even going to come close to supporting a 1100-1200 hp engine with a single 4 cast intake. Truth is theres a ton of time in this. I'm fortunate in that john and i are friends and he didn't charge me too much extra for me to "help". I have more time in mine than i thought it would take him. And he had a bunch more time in it than me. You're looking at $4000 maybe more either way cast or sheet. Its what it is. If you put a $1500 ported victor on my engine I suspect you would watch 150-200 hp disappear. And no its not all cut into a hundred peices and welded back together......lol.

And while we're at it carburetors.....forget $500 used dominators and new $850-1000 carbs.
Nope we are in the land of $2400-3000 carburetors. Time to put your big boy pants on and step up. These carbs used fetch $14-600. And you gotta have it. Put a 1050 dom on it and wave goodbye to lots of power.
