B cam?

[91ghp5.0]

This is kind of a strange question for talk, but I'm not quite sure its "tech" qualified.

So! For all of you guys out there with B-cams (or if you dont have one, and have the answer, come on in too!), what is the generally accepted "power range?" I KNOW my stock tach is way off, but i have a shift light hooked up to my MSD box, and i have it go off around 4600 or so. I know the real way would be to hook it up to a dyno, but that's not gonna be for a month or two. Any ideas?

The bcam is a higher rpm cam, pulls like a mother up top, not a whole lot down low. When I had my stock intake, and just the bcam, i would reiligously shift at 5400, nothing more, nothing less. When I did my explorer intake, I could shift my car to 6k rpm no problem. But the track proved I was making no power up there with the stock heads. I was running 13.5's shifting at 5800, went back down to shifting at 5500 and pulled a 13.3 the first time. Every car is going to be different, but i'll tell you right now for the bcam 4600 is low and youll get there VERY fast. Id shift somewhere around 5200-5500. Hopfully with the heads ill be making power up past that. Engines being ripped apart tomorrow for the heads so ill let you know how it goes

the car just sounds like it's dying up that high. maybe i'll try shifting that high tonight, we'll see whats up.

Maybe you have a timing problem or something else. Ive been in a couple of cars with b-cams and they diddnt open up till like 3k.

mine gets going right about 2200 rpms, and then i usually shift at 5k on the stock tach, which is way off, according to my shift light (wired directly to MSD).

i have a B cam and it starts making good power at 4000k
it pulls to almost 6000k

hmmm. maybe its time for some "dyno time" for me to see if my timing it good.

hmm maybe its time for me to get an aftermarket tach

i have a b-cam that i advanced 4 degrees, which should shift the power down a tad bit.

my car starts pulling around 3k and pulles to around 5600 or so....

I have what I believe to be a stock cam, but it doesnt pull hard until 3k either, it pulls right to 5500 hard though, whereas all the other stangs I been in that have stock cams pull a lot lower and shift earlier. Any explanations? I can post a vid of the idle if it helps.
