Smallest cam to reach 400 rwhp?
Just like the title says. What is the smallest cam you can run in a 346/347 and reach 400 rwhp?
Heads would be P/P LS6 with either a LS6 or FAST intake. Exhaust would consist of 1 3/4 Lt's and TD's.
Since it wold be a small cam would you have to rev it high to achieve 400 or can it be done with out rev'n it up to high?

the fast intake will help if you wound up getting one but something like a 220/224 on xer lobes and get your dcr up in the 8.5-8.7 range and you should clear 400 with just an ls6 intake imo.

long tubes and an ory with a merge collector for the Y or 3" true duals dumped, ported fast 90 or ls6 probably and ported TB to match it, top end kit of some sort maybe(rockers, retainers and springs)EWP, crank pulley, lightweight wheels. Exotic bolt-ons is a funny term and making 400 rwhp on a stock motor with just bolts-ons is like impossible. Rod bolts arent bolts ons. Unless your using a power add like n2o I dont see it being done unless it's all on paper and your using a generous dyno to prove it.
Cam only or just do bolt ons and be happy but you'll still need the bolt-ons to support the cam

With my current 218/218 cam on my '99 SS I pulled 400.3 RWHp at 6200 RPM. The car was a head/cam/intake/exhaust/gear/tuned car, stock displacement. Of course, I went and blew it up.

I'll be shooting for 400 with my 216/216 .581/.581 cam with ported LS6 heads and a stock LS6 intake through longtubes and true dual 2.5" exhaust. DCR will be in the 8.6 to 8.7 range.

I hit 404 rwhp on my orig. LS1 w/ stage II heads, 224/228/114 cam thru a Moser 12 bolt.
Now I am dropping in an LS6 w/ ported LS6 heads, same cam, Pulley, same rear.
We'll see where that ends up.
