Thanks! I can't seem to find any way to optimize this motor any further. It's met my goals 100% and it's not even in the car yet! LOL... Can't wait to get it on the track.

LOL...It's pretty typical and in fact, downright plain. The headers pictured are not correct. I'm having custom 2.25" ones made up. The direct port is a Nitro Dave work of art. This has been a long road so far. The motor pic is before I had the front plate fitted properly. Here is a link to the chassis build:

Is this a outlaw 10.5 car?

Starting with 500 Damn ! We hope to work our way up to that with our tall deck motor. If ours doesnt make over 900hp N/A I'll be disappointed.

Believe it or not, it doesn't fit in any specific class. This is a fun car for me although I'm planning on racing in whatever series I can get into. The IMSM heads up stuff looks good so, I'll probably start there. This motor was designed from the ground up (like yours) for a TON of nitrous. 500 was designed as the starting point although I don't expect to go over 700-800....

As far as tires...Starting with 31x16.5x15 ET Streets on a 15x14 wheel. Not going to spray the first season. Then, I'll probably go up a size when I spray. I'm sure you'll make 900 HP no problem.

LOL...Motor was done the beginning of this year. The car...Well, that's another story. It should be ready before the end of this season...I hope. this started almost 4 years ago as a simple project to build a forger LSX with a Procharger and spray and here I am 4 years later with this. Have a look at the link I have in the thread. It's like a boat that I keep pouring more and more money into. The good thing is, I'm actually getting close.

Didn't want to mess with the heads and reduce the size of the chambers. Been messing around with the design a bit (with EAP) and haven't seen any real benefit with higher compression given the entire combination.
