The ring gaps are a bit bigger I think. I'm not going to race this thing, and the shot is only going to happen if I get bored of it. I think that we are looking at about 475 hp, someone had said 515 before but running numbers doesn't get that.

 

It will scare the **** out of you the first time you step on it regardless. Thats what I love about cars most. When I put together any motor and that first time I punch it. Even with a pick up. Its the anticipation of what it will do.

 

I can't wait. The most powerful car I've ever had would either have been my 72 Nova in High School, or my 94 Z28. This thing should smoke them by a long shot.

 

And then there's the ones I hoped would scare me, and didn't with the first drive! That's always disappointing. My Camaro did that when I first rebuilt the engine in 1999-2000, and I put the new Edelbrock carb on it. I was hoping for tire frying performance, sorta like it did when I parked it 11 years earlier. Darn thing would barely break the tires loose!
After a lot of fiddling I went back to the old Holley 750, and instantly she was a changed engine/car! Amazing what one little change can do to make or break performance.

 

Well, an update. My buddy who ported the heads took them up to the machine shop he uses to show them off. They were so impressed that they are going to open them up to 2.02 intake and do the bowl with their $160,000 valve cutting machine. It cuts the valve seat and into the bowl like over an inch. These are going to be the baddest Vortecs in the world I think. No cost. I'll end up owing him some website work or something I'm sure, I can't not pay him.

Right now the heads flow 254@.500 with the 1.94 valves. The heads are milled right now to 60cc. The camshaft that is a going to be ordered custom Bullet solid flat tappet, 247/256 @ .050, .570/.556 on a 106lsa installed at 102ic. Air Gap intake that is ported and polished and a holley 750.

 

I'm not sure what you're talking about here? Are you saying they unshroud the valve around the bowl area? If so that's pretty standard for a SBC head with 2.02" valves. They have to unshroud the bowl area just to give the valve some clearance for flow. All the stock heads were also done this way.

 

This machine is fully programmable. The tech can custom design any seat configuration, and beginning right at the seat continue right down into the bowl, perfectly, cutting a preprogrammed amount down into the bowl. Just need to do minimal hand blending. This machine moves faster than you can see, and automatically moves the head and lines itself up, feeling the starting point each time automatically. It is crazy.

 

It cuts the throat an 1" deep I take it. It sounds like the machines we have at work. I have the same HAAS cnc's that AFR and and other big companies use for their work. It sounds like it uses a cutter instead of a stone for the seats if they can change it to come off and tapper directly into the last angle on the seat. It sounds cool. Much different then a stone on a arbor inside the valve guide.

 

It is a cutter, not a stone.

 

I sold a few parts, I'll be ordering up the cam, some solid lifters and the pushrods soon. Awesome!
