    Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car. Horsepower is how fast you hit the wall, torque is how far you take the wall with you.

    Power band will be shifted up with the cam. You'll possibly lose some low end torque but you'll make up for it on the top end.

    The cam is bigger than Pauls cam he netted 450+hp without porter heads I'm porting the heads I know it depends on air etc but I'm almost near Charlie specs on motor work except cam specs his is higher due stall

    While I would simply be guessing on HP numbers I want to point some things out. Porting the heads on these motors does not seem to help out much, and depending on the port can easily go backwards on HP and Tq numbers. Secondly there are a few things with that cam that I personally am not the most fond of with these heads. Number one, the split is far too big for an NA motor in my opinion. We run a split that wide for our "b" cam, but it is designed for a blower. 2, the 112 LSA cam's are always more difficult to tune regardless of what anyone else might say. Now that doesn't mean they are impossible to tune but they usually are worse performers on an L92 head/ls3 intake then the 114 lsa's do with all of our in house engine dyno and chassis dyno testing, could them make more peak power? maybe, but what does making 470rwhp do if you get stomped by a car making 430? (hence why we don't even offer a cam tighter then 114 except our "R" series of camshafts, and that is only for someone who wants a choppier idle and doesn't care how it drives)

    Now by no means am I saying don't try it, but don't get hung up on the peak numbers. Paul may have made 452 rwhp, but he ran numbers backing up the dyno outrunning many other cammed/converter/tire cars out there while being on stock tires, converter, and all... Don't got on an HP quest and sacrifice performance...

    With those specs you'll be making more power up top. Don't get to caught up in the number game either. If i were to guess im going to say 430-440 to stay conservative. Im interested to see what you will net with ported heads. I would like to get them done as well but don't have the money right now so im playing the most hp/cheapest game LOL. The exhaust side on the l92 heads isn't that wimpy but if i were going to port them that's all i would do.
    Can't move out its own way- idk what number motor its on, how much boost, how big of a shot, its starts, im happy.
