Im sure with some fine tuning the gas mileage can be improved with the installation of the timid and mild P-425 cam. Now about completion The boss would not approve overtime so things are at a stand still until the first shift Monday.

Re: Potvin cam specs
Gas mileage (low that is) will be improved upon . . . it should be even lower with the P-425 . . . but you'll look and sound cool, so who cares!
I've ran both the 3/8 and 425 - my choice for the street would depend on the cubic inches of the engine, the valvetrain and the rest of the car . . . gearing, flywheel, weight, etc.. The 3/8 is obviously a more timid cam - so in a heavier car, with a light flywheel, with lower gears - might be a better choice than a 425. I guess the final answer is "it all depends!" LOL! You'll do well with either one B&S |

Re: Potvin cam specs
The 3/8 likes gas is is not good for mileage .
The 425 is much better. But i swap the 425 out for a Schneider 270F on my 304ci . More Street friendly . The 425 kicks in way too late. I wanted a H&C 6732 from Pete , but since we dont have cheques anymore in Germany for payment And his post office is not able to ship to forgein countries ,Schneider is my second best choice. I used the 270F before with great results, but always like to try something new. So if anybody on here is able to help me to get a h&c cam from Pete , i would be very happy. I will post the results . Regards Michael PS .... all my info is from what i tried , not reading the internet. Best all around cam for big engines .... isky 404-A Did 104mph in pendine 102mph for schneider 270F :-) I am not a racer , just like flathead engines. |
