I am looking to get 325-350 HP from my 1973 351W.
Call me skeptical, BUT........
Here's the claims:
1. Windage Tray: claims of +20HP
2. Roller Rockers: claims of +15-40HP
3. Underdrive Pulley: claims of +15-20HP
4. K&N air filter: claims of +10-15 HP
Are they trying to tell me........ Just by bolting on this stuff (Less then $300), I could go from a stock 225HP to between 285HP & 320HP ??????
If this is true, why would I spend $2500 for a set of aluminum heads, Cam, Intake, Lifter, Pushrod, Valve Springs, Valves, Retainer, Gaskets........ TO GET 75 MORE HORSEPOWER????
