Why do you say that?
I'm talking about the material removed from the valley for the push rods..
Nothing left of the deck..
I could be wrong, just looks scary to me..

I really like this build.... I've been considering a build with a 4.56 x 4.375 short to get cross rpm in the 9000 range and keep piston speed around 6500fps. Shorten the deck, SS style lobe relocation, keyways, individual shaft rockers, Braswells, dry sump, "good" ring stack w/tricky gaps ( ), piston guided rod, etc.....the bells and whistles. See if Eric can send me raw a set of Milleniums and do some manipulating with chamber volume, port shapes, etc.....

It is a raised cam block by Indy. We made 1359 at 7200 and at 7500 we dropped off to 1354, peak torque was 1017 at 6800. We are changing cam acarbs. we think with the lobe seperation we are running it should have continued to buid hp to 7800. Something has to be stopping it , our guess it either the cam or the carbs. I plan at least 2 more dyno sessions. Then the track.Pete or Chuck if you se this you are welcome to post the dyno sheet.
Nice.....

Nice.....
With the paeks that close together, if you can get it to peak around 7800, it could be 1400+.
Either way, that is impressive power.

We are changing cam, carbs, valve springs , rockers and valve seats on the intakes. We will be back on the dyno in a couple of weeks.
Sweet.....
I know Yellow Bullet isn't for everyone, but this should be posted in Chris Uratchko's N/A section. I'm sure alot of people would like to read about it.....especially the guys who like HEMIs, who just happen to be some of the sharpest cats over there......like Lobes and George Bryce.

Why are you having to change valve seats?
