Price Vs. Performance
Here's where this gets interesting. The Brodix, Dart, and TFS heads all made strong peak power, leaving the Edelbrock slightly behind. Then we divided the price of each pair of heads by their peak horsepower. Here, the Edelbrock is the clear winner in terms of horsepower per dollar. One note for clarity's sake: We added the price of the Brodix CNC chamber modification to the price of the heads, since that's the way the heads were tested. What this shows is that the Edelbrock heads offer excellent power for the money. There's something to be said for combining value with all-out power.
| Heads | Price (pair) | Dollar/HP |
| Edelbrock | $1,779.00 | $3.05 |
| TFS | 2,095.95 | 3.52 |
| Brodix | 2,358.90 | 3.95 |
| Dart | 2,483.90 | 4.17 |
