Default LT4 Heads+Cam #'s?

Im looking to have the stock heads ported and a pretty good size cam installed. Wanting to see what kind of solid numbers you guys threw down. Also about how much yous spent for the build. Im trying to keep it simple and make about 370 or so to the wheels. Throw me some numbers!

Llyod has numbers posted on his site. 370 rwhp shoud be doable on a stock bottom end LT1, with the proper supporting mods.

Why not just install the LT4 hot cam kit, HD timing chain kit and some LT headers. That should get you in the direction you want to go. However Lloyd Elliot is the place to go to for some advice and some numbers.

I had ported heads and cam on my LT4 a few years ago and dynoed in the mid 360's RWHP, so 370 shouldn't be too much of a problem. Who's doing the heads?

The cam I used was the GM846 cam;

222/230 duration @.050
.542/.563 lift with 1.6 RR
112 LSA

You can obtain a 400rwhp fron LE. If I where you get all you can cause your only gonna do it once and it will still be streetable. Your cam may have a lope to it but thats a good thing in my book. Just make sure the combo coincides with your gears and stall(if auto) and tell them where youd like to see the power to be(low middle or up high). I got 365 hp on LT1 heads and a small cam 215/224 on 110lsa. When its all done, you will be beating C5 Z06s and may be able to run with C6 Zo6. Not bad for just heads and cam.
