There's a lot of options; it depends on how much streetability you want to give up, and whether you need to retain emissions status.

What state do you live in and do you need to adhere to state emission requirements? 400 hp to the ground is easy and the different paths you can take vary.

As for where to buy from? All of your sponsors on the right are excellent and many many have what you are looking for.

M6 or A4? M6 cars are more tolerant of big cams imo. Gears will help a lot with streetability also.

OK, then the TR224 on a 114 LSA is your cam.

I love planes, and I work for the air force myself! (Civilian)

LS1 fbody engines have a truck cam that is a bottle neck in an otherwise awesome engine, so LS1's respond very well to cam upgrades.

TR224 is a cam offered by Thunder Racing that is VERY proven around here (with LS1Tech people) I ran one for a couple of years. It's the biggest cam that will pass smog in Cali without going to extreme measures. You will stil need a pcm tune, however. Specs are 224 degrees duration on both intake and exhaust, 0.563 inch lift on both intake and exhaust. They offer it ground on both a 112 LSA and 114 LSA (Lobe Separtion Angle) The 114 LSA version has a smoother idle and lower emissions, but power comes on 200 rpm later. Go with the 112 if you don't mind working a little harder to pass emissions. You will need a set of Comp 918 valve springs to go with this cam and most other LS1 cams.

That's the model of the cam he's suggesting.

TR224 - Thunder Racing (sponsor on the right) 224 duration cam...the lower the duration the more emission friendly

114 LSA - more emission friendly than the 112 LSA

With a 224 cam you will have to work hard to put 400 hp to the ground, but it has been done. You will need all bolt-ons, and some good heads and a good tune.

I design test stands for testing changes made to F-16 aircraft flight software.

As for heads, there are a lot of choices depending on how much money you want to spend. The cheapest would be to home-port your own heads and retain the stock valves, or you could spend $3000 on the best heads with bigger valves. You can pick up 20 to 40 hp on heads alone.

For more information on LS1's and fbodys, just keep reading on this forum, you've come to the right place. I'll answer more questions though, if you have specific things you want to know. If I don't know the answer, somebody else on here will. I've driven fbodys my whole life, starting out with the '67 models, but hey, I don't know everything.
