What do you mean by remade the shortsides? what did you do?

1050 is one of the part nos in the AFR210 range. I wouldn't know how the current specs compare to heads as old as yours.

Are yours CNC ported?

I am trying to make any sense of what this engine is and what the application that it is dominating in.

i Think 13 deg heads on a steel block.

Was the old cam also from 2005?

Come on now, you cannot tease us, numbers to go with the video. The dyno I use is low vs some of the others. Last time I posted a sheet from it from another one of my personal engines I was told it was bad, so I'm not posting a sheet. I'm going to put it in the car and test the wheels off it. Then ...

Is it a well set up car?

What car is it going in? Weight? How long before it see the track?

Looking forward to some results.

Why didn't you put more compression in it?

What was your minimum port area? It carried power well up high.

Just a general question. If you have two 632 engines and both the same parts, meaning heads, intake,carb and ignition except one has 10.5 to 1 compression and one has 15.5 to one compression. Approximately how much difference will there be in horsepower? This is for a guy that just wants a weekend ...

Yeh I've seen over 660hp with a 1.4" 950hp. But don't know plenum vac. I suspect it was a big restriction. Will you keep record of plenum vac when you are trying your carbs?
