Yes it does kill the drivabilty, because the reason that cam sounds so sick is because its crap at low rpms, hense the rough idle. Youd never pass emissions with one and cars with those cams are designed to be launched off the line so they never have to use the lower rpms. Yes it does sound totally sick, but at low rpms it would drive like crap because the fuel air ratio is so crappy. IMO drivabilty depends more on the cam than anything else. Try driving that car in traffic.

 

Good Vid

 

I read that the idle clip he showed in the video was with open headers before he put on the true dual exhaust, I've thinking it's more than streetable. Hell, a healthy stock motor with open headers can sound sick, and it's streetable.


Good video BTW, watch it bunch a times. Good friend of mine has a 94 LT1 Z28.

 

Yeah but realise it probly has a 2500-8000 rpm cam in it. Try that in traffic.

 

Man, please don't even start with something like this. Go over to LS1tech.com and look at the hundreds of guys running a cam in their daily driver. Know the car before you spout off something like this. An aftermarket cam in an LS1 is a VERY common mod.

I've got offroad headers and x-pipe sitting at the house, I don't care about emissions. I'm sure most of these guys don't either.

 

Did i say after market cam? Or did I say 2500-8000 rpm cam? Either way, I meant a really mean cam gives you that idle, and that screws your streetability, Im sure its possible, but still. I never said aftermarket cam, not all cams are that radical obviously.

 

They are totally streetable. the h&c swap realy doesn't take away from the drivability. MPG goes to POOP but the power gain is unreal. I'm gettig ready to drop the LS1 hotcam in mine. It has a short LSA and sounds mean as hell but only pushes @ 80 hp over stock. But when you go to the bigger Comp Cams or T-rex cams, they idle like stock but w/ good heads can break 550-600rwhp easily. It's all in the tuning. But the rearends are a VERY weak link. I KNOW!!! Luckily mine was still under GM warranty HEHEHE. they bought it, but I had to get the 2.73's again. I tried to talk them into 3.42's.

 

Im still sticking with the notion that big cams are bad for street. I dont see how they can be good for street with horrible bottom end. Or maybe we are just talking about different cams.

 

I agree with Aliate X.

Like I said in my previous post, unlike SC engine, NA engines making mega power will make less at low rpm.

And I don't mean any aftermarket cam; as the milder ones are obviously alright for street. Really depends on what you consider "totally streetable". Sure it'll move, but do you have to slip the clutch for an hour just to roll out of a stop sign? And always have to be in a low gear as the engine makes no power at 1500 rpm?

Tell me, the cams that make 600 hp NA, how much torque is available at 1000 rpm? or 1500 rpm? If it's much less than stock, then your sixth gear would be useless for highway cruising with stock gearing.

A 700 hp makes more torque at 1000 rpm than stock. You could lug around at 1500 rpm and it'll pull like a champ.

 

Well, right now my basically stock LS1 is ballless under 2k rpm. but when 2100 on up hits, it pulls like mad. I have driven other cars with different cams and they all seem to start pulling hard around 2500 and just cruising the streets they are very tame and easily putt around. With the lock up style converters, the 3000-3500 stalls are very tight and are like driving on a stock converter. But when you are cruising along at 25-30 mph and drop the hammer, flash the stall, hold on to your *** cause it might get left behind. Also, when the bigger cammed cars can run up 6800 rpm, there is no reason to worry about a shorter powerband. They will pull hard from 2500 up to 6800
