I'm new to the forum but not new to muscle cars. I raced for years. Everything from Dirt and Asphalt super latemodels to 10 sec street cars. I have always done my own work. Everything from the idea to race day. Here is the problem... I have only built small blocks. Building the motor does not concern me, building a blown big block with the right parts does. So with that being said I would be grateful for any feedback.

There are several things I know for sure...
1. Its race only (68 big tire Camaro that hasn't been street legal since 1979)
2. I currently own a 6-71 with dual 660 holleys.
3. I will be using Darts big M 10.200 deck. Thinking 572.
4. I know I should shoot for 8.25:1 to 8.5:1 compression ratio.

I need the motor to live obviously
I know the 6-71 is not very big but I couldn't pass up on the deal I got.
What crank do you guys recommend? Callies, Bryant, Crower? Are these overkill?
This is not a "no expense spared" race car. I do need to eat.
Heads, heads gaskets, Pistons, valve train, timing system, wet or dry sump?

Please keep in mind I don't have bottomless pockets. I currently have a 2010 Camaro with a race weight of 4200 lbs and it runs 10.8's all day long. The current motor is just over 700 hp. To go any faster I need to stuff another $20k in it or start cutting it up. I can't bring myself to cut on this beautiful car. Plus, the cost of 'go fast parts' for this car is outrageous!! For example... my Meziere water pump was just over $900. This is why I bought the 68. Sorry for the long post and thanks for any advice.

Thanks,
Shane
