If you get all the bolt-ons, and a "big" cam. Will the low end be slower than it was stock? or will the bolt-ons make up some of the low-end the cam lost. Can someone with a somewhat large cam, tell me how much low end the lost after the cam swap?

yea you will gain more top end than anything it seems like.. just put a high stall converter in and it flashes ya right to your power band! You'll love the top and pull though.. especially with a stall.. You come outta the hole hard as hell and the converter holds it up from there on out!

Yea, you can counter that loss with a high stall and proper STR. The gears will make a difference too but I think the stall would be better for the money. I'm wanting to go with a T-Rex or equivalent for a winter project so I'm gonna have to step up my converter to around 4000 or higher and then I'll have a lot more in the mid-range and high-end but the higher converter will still keep my torque.

I had a trex and I gained everywhere lower, mid, upper.
Of course it really started pulling 4k+
Gears and a converter will help you get into the power band quicker.

an x3 has less low end than stock. I know because I drive one everyday. my car is slow up until about 2500rpm, then its a bit stronger than stock but by 4k hold the **** on because you are glued in the seat. I used to be able to breaktoque my mt et street radials before my cam, now I can't even break them loose with my linelock.

"I had a trex and I gained everywhere lower, mid, upper part of my dyno curve which started at 3000 rpm. "
It would really go against conventional wisdom if you truely meant the lower, middle and upper parts of the entire rpm range.

Gears, or bolt-ons?

Therefore, it creates the illusion that you have no low-end.

There have been many, many guys, me included, who have over-cammed their setup and lost lowend. There are ways to try & fix the loss in low rpm cylinder pressure. Jacking up the ignition timing, advancing the cam, raising the static compression with thinner head gaskets, & using variable duration lifters (Rhoads) are some of the things that I did in the past. Actually, the best solution in dealing with the ill effects of too big of a cam would be to change the cam for a smaller one.
