[Roadsters] Cam option?

[jover4x4 at aol.com]

Tom,

With 44 Mikunis and a B cam I noticed a bit less power and torque at the low end but the car was certainly drivable on the low end even at 5280 ft elevation.? A 3.90 rear helped the low end drivability.? It really took off at 3000 rpm and?pulled hard?to 7000.? I?ran 34mm chokes instead of the stock 37mm since I am at high altitude. 

I think you will be very happy with a B cam.? I know some guys at sea level have run more lift and duration than the B cam but I don't find that necessary for a street car.

Good luck.....You will have fun.

Hello list,
   
     I am now about finished with my U20 to MC Mikuni flatslide conversion and 
now looking to upgrade the cam. With my A cam at present I hit the wall @ 6k. I 
have never had the chance to drive a B cam car. What am I to expect with a B cam 
if I go that route? Little sacrifice in the low end punch and perhaps rev a bit 
higher than 6k? Rallye puts it as just that,do you agree? I don't want to give 
up much on the low end as I have 4 big holes to overcome rather than 2 now but 
would like to wake it up a little on top end but not give up my midrange. 
Suggestions?
                          Thanks, U20, Smoothbore 40mm Mikuni Flatslides
