P to V

Do you have longtubes and or any other bolt-ons? Shoving a donkey dick cam in heavy *** car like a GTO is recipe for shitty time slips and getting your *** cracked on the street...but it sure will sound mean! I would stick to a cam with 8 degrees or less of overlap if this is your daily driver. There are several factors that determine P to V, not just lift, you have to consider the amount of advance ground into the cam along with duration as well..

Its my brothers GTO and he has lts and intake(not manifold) and he bought a donkey dick cam cause he wants it more for sound than E.T. if its faster than stock and sounds like John Force he would be satisfied.

Its a little bigger lol but he wants it to sound like a dragster and I'm gonna build him a set of heads next year at school so that will help some once I actually do it.

Putting that cam in stock displacement LS2 is pissing in the wind, even with heads. He would need 400+ cubes to benefit from that cam. That monster has 27 degrees of overlap and is going to be a nightmare to tune in any drivability with a stock motor. He can get good performance and a choppy idle from a smaller cam that won't **** his drivability.

If he just wants the dragster sound but still drivability why not just drop the lobe seperation and increase the duration split? You don't need to put a cam in that big just to get the sound. My 02 had a reverse split cam with a 110 Lobe sep. and it loped pretty hard. Personaly I would have gone with a trex or somthing along those lines MAX. They are proven to work with stock heads. That thing is going to be a dog out of the hole and he'll probably have to raise his idle way over 1k rpms. Plus if it's a daiy driver he'll need new valve springs at least once a year depending on miles driven.

holy hell!!!!
this guy i know put a 238/242 604/610 112lsa in his stock cubed ls1 goat and that cam is WAAAAAAAAAAY to big for it... he revs that bitch to almost 7K and he only ran a 13.0... sounds good but man if i spent that much on a cam i would want more outta it, he made ~400 to the wheels... not a good choice for your bro, slap him on the head and tell him he's an idiot!
