That's some awesome power at 7100 and peak torque at 6100. Let us not how the reverse cooling dose, if it picks up anything.

it's interesting how Pontiacs had reverse cooling on the V8 the first few years in the 1950's and now they are going back to it

We are not done testing but so far the power has been the same with the reverse cooling ,however we believe wew can get more agressive with cylinder filling and higher cylinder pressures with the reverse cooling and eventually make more power.Bill C.

I'm gonna guess that motor detonated itself to death. If it was on pump gas no doubt, in another post they state 112 octane and in another pump gas, witch was it? The approach was all wrong no matter how you look at it. Lets help this guy out, we need to see what the outcome of the teardown shows. I'm putting my money on upper rod bearings are toast.

Big Speed, this is your 450cfm CNC Tiger engine that anyone can buy?
You have picked up 20HP, nice work. It was 1052 HP.
You guys are closing is on a 1100HP easy to build Pontiac single 4 race engine.

I think we are going to find out soon enough, pretty sure there's one going in a car, but don't know the details on the car.

Why wouldnt it.
Thats the beauty of CNC. CNC heads and intakes come out the same every time.
So if you run the same cam with the same shortblock their is no reason you can not duplicate it.

Why not, I mean out side of the carb, why couldn't I bolt them on my short block and make the same HP, We know the quality of the short block is important, good rings. Ring seal, as light as possible rotating assembly. I'd like to here your reasoning why.
