Exactly, these dudes that ran their hell cat were making fun of it, and I ran the same time as them lol

And you spent less money to run the same time.

Soooo I did the cam and springs today. Went really smooth. Picked up a TON of power. Need to re tune it now.




so did look at the part number on the cam and it was a ls1 cam. So it is a late model ls1 cam so it was 198/208@50 idle sat at a very nice 21inhg, the cam in it now is a 228/230@50 and idle is around 12inhg. I'll take the loss because it sounds great and seems to work well. No cam bearings were hurt in the swap and no lifters fell in the pan

You shouldn't have lost that much at idle. Tweak the AFR and timing to get some VAC back. Unless you are talking about at idle in drive?

Got the tune pretty dialed in it idles solid at 750rpm now and got it to about 16inches of vacuum. Pulled some fuel and added some timing. Backed off the timing up top due to the pump gas and compression in it. Accidentally hit 20psi on the highway which was awesome.

Those "accidental" 20psi hits are amazing.

Glad you got some vacuum back. Tweaking the tune usually helps quite a bit.

Yea in retrospect I probably should have gone with the smaller cam. But it's done now and I'm not swapping the cam again. I've got the fuel side dialed in really well, freeway cruising is at like 34degrees of advance and sits at around 15.5:1 which is where I was getting the best milage with the ls1 cam.

I bet it sounds amazing.

I have the sloppy stage 1 and do love it though. I'm on the baby 4.8 motor though, I wanted as quick of spool as possible. I went with a small cam(212/218) and a small crossover(1 7/8").

During cruise as well it's best to tune for maximum vacuum. It'll help with mileage too even though you may end up a little richer overall.

It's honestly no louder then the ls1 cam at idle, you hear a little chop but not much at all. When the wastegate opens at wot, it is alot louder. Also the valve train is a tad louder now

Got the boost dialed to 15-16psi. It's absolutely hilarious. I feel confident at this point it will do 10s on pump. The cam and springs are so good in this car right now. I really need to dyno it and see what it makes on pump. I'm running very low timing and it's still a total animal.

My goal is to run out of gear in the 1/4 so that means I need to trap 142mph
