Alright guys, I know cam questions are asked all the time, but I've done searches all over the place and I can't find any comparisons. Anyway, I'm split between the two. Here are the specs of each.

B303:

Durationat050inchLift: 224 int./224 exh.
IntakeValveLiftwithFactoryRockerArmRatio: 0.480 in. ExhaustValveLiftwithFactoryRockerArmRatio: 0.480 in. ValveLiftwithFactoryRockerArmRatio: 0.480 int./0.480 exh. lift

TFS Stage 1:

BasicOperatingRPMRange: 2,000-5,500 RPM
Durationat050inchLift: 221 int./225 exh.
IntakeValveLiftwithFactoryRockerArmRatio: 0.499 in. ExhaustValveLiftwithFactoryRockerArmRatio: 0.510 in. ValveLiftwithFactoryRockerArmRatio: 0.499 int./0.510 exh. lift

Thanks all!

I'm asking cause I honestly don't know...why would you suggest the steeda over the TFS1?

While were talking about the B cam, what exactly makes it for 5 speeds only?
Ive seen it listed like that on sites like Jeg's.

the B cam is very lopey, and without an aftermarket stall converter it can make your car jumpy at a rolling idle

What exactly makes a better duration spec? The steeda has 1* less on the intake than the TFS but 1* more on the exhaust. I'm just trying to learn here...

the tfs and steeda cams are both good cams, from experience of dealing with the trick flow stage 1 cam, its a great cam, bettre than almost anythin the fms has. the steeda cam i kno nothing about so i wont say good or bad. but the difference between the two i hear is minimal. i would go with trick flow, they are good cheap and reliable.

Well then I guess Ill have to go with something else. I still have the stock converter for now.
I found a used B cam on a local forum for $65 so I thought about getting it.
