OK guys need some help choosing a cam, car is going to be mainly street driven but will see a fair amount of track as well. Here's the engine specs

404ci
4.010 bore
4.00 stroke
10:1 to 10.5:1 compression depending on how much I mill the heads
As cast LSA heads later will probably get them cnced
Head lift will be the limiting factor As far as boost but I'd like to see 18lbs
Studded througout
E85
Turbo will be either a forced inductions hp88 or just a s480 96/1.32
Th400 or 4l80

Car should weigh in at around 3100lbs

So let me know some ballpark numbers on what you think would be good, thanks Nick

you know that head lift is a factor keeping you to 18psi !!!! but you want to mill the heads for your compression ratio !!!! thats the last thing you want to do !!! making the head lift problem worse!!!! anyway cant help you with cam but i am running a similar 408 lq9 ls7 style heads etc with s400 hp-88 waiting on results soon with this new turbo/head manifold combo !!!! compared to s475 stock 241s etc !!! cheers

236/232 115+2 or crane shelf turbo grind (232/228 115) unless you get a bigger turbine. The crane grind should take less spring since it's a slower lobe profile.

I'm curious to see how well these heads handle higher boost. I want the compression higher for better response out of boost. I'd like to see 900rw and don't think it should be a problem getting there before lifting the heads

I would do something like either of these two:

234/234 .612/.612 114+4

or

236/236 .612/.612 114+5

I can have either of those ground for you and to your doorstep in a 5-7 business days. We also have a kit that comes with springs and push rods and many other options: http://www.tickperformance.com/tick-...r-ls6-engines/

Just substitute the Polluter V.1 for your custom grind.

Manifold is gonna be a Vic Jr with 6061 elbow

If that is the case do 236/236 .612/.612 114+4.

I would really like to see you use at least the HP88 if not a GT5018 or S588SX5.

If you did something bigger like the S588SX5 my Stage 3 cam (236/238 .612/.595 115+4) would work well.

Looking for input on the manifold too

I like the choice. A lot of guys are scared of a single-plane and an elbow because they've heard about distribution problems with airflow.

Unless you are really leaning on the tune-up or you're just being plain stupid with the tune you're not going to blow anything up.

Keep a little extra fuel in it and/or run a step range colder plug in those back holes and you'll be fine. That manifold will make more power than just about any other off the shelf manifold you could put on it, and with a turbo, mid-range power is ridiculous anyways and you won't even miss the 5-10hp you might lose at 2500rpm before the turbo starts to come on-line. With you're cubic inches, the turbo you are looking at and this cam you'll never know what lag is.

It means what he quoted of the other guy is nonsense. He is laughing at what the guy posted pretty much.
