But I wasn’t yet happy with the performance and didn’t think it was ready to be competitive in Autocrossing. For one, the large cam had no low-end torque at all and required operation above 2200 RPMs to get moving. When I bought the Camaro it had some 186 casting heads—very good factory heads “double hump” heads—but I wanted something more. I watched eBay for months and did a lot of pouring over tables of flow stats for heads trying to decide which heads I wanted to put on the car. I was also planning on going over to electronic fuel injection on the car because I don’t know how to tune carbs and wasn’t interested in learning. Aluminum heads were a must to decrease the weight of the car (aluminum heads are good for a 45-50 pound reduction over cast iron heads on a small block Chevy) and to improve weight distribution. Additionally, I wanted to run as high a compression ratio as possible to take advantage of the EFI and produce the most power. The generally rule of thumb is you can run as high as 10:1 with iron heads and as high as 11:1 with aluminum heads on the small block Chevy with premium gasoline. Here in Hawaii Premium is 92 octane, so I was planning on between 10:1 and 11:1 static compression ratio for the street with EFI.
