Need engine advice - Cam, and more
I'm new to this and I need some help, there are probably a bunch of mistakes in this post as to what stuff is listed under and everything, so i apologize for that in advance. I just really need some help on my build. I have no past engine building experience, and no experience with LS1's...the build I'm going with is just what friends have told me to use, and combinations on this site that I see make big power...
I'd like to get some opinions on my engine build, and what I need/don't need and also what cam to get. I'm trying to attain the most possibly horsepower from a non FI 346 LS1.(I may go to a pro-charger in the future) Keep in mind, this will be my first engine "build" so I don't really know everything...I will attempt to disassemble/reassemble an old school 350 (has two spun bearings, so now harm can be done) before I attempt the LS6 build up.
The engine will be going into a Pro-Touring 68 Camaro.
I will start with a low mileage(hopefully) take out LS1/T56 from a salvage yard. I'll try and give as many details about the drivetrain as possible.
Engine Details:
Patriot Performance Stage II LS6 Style Heads
Cam - ?
LS6 intake manifold
MTI Billet 75mm Throttle Body

The entire car except for hard line will be converted over to SS braided line and AN fittings
Car should weigh in at about 3350lbs w/ me in it.
So here are my questions:
What cam to get? (Keep in mind, I want an aggressive cam, but the car will see just as much road racing and auto-xing as drag racing.) Also, how will these cams act on the street, and what kind (rpm) of an idle am I going to be looking at?
The cams that I am looking at are:
Comp Cams CC-Custom7 (231"/237" .589"/.595" 112LSA")
Futural Motorsports FM-F13-114 (230"/232" .591"/.585" 114LSA")
TSP Custom 231/237 Cam: 231/237, .598"/.595", 112 LSA
G5X3 (Specs? I'm not even sure who makes this cam, but I know people make good power with it)
What Ignition?
What Valve Springs?
What size fuel lines?
Who should I have tune the ECM? I'm in NY. Cartek?
Thanks for your time and any help you may provide,
Ralph

Here are my simple answers to your questions.
Call on your vendor of choice and get their advice on a H/C package.
Go with the stock ignition.
Call Speed inc. >>>>>>>>>>>> about the fuel stuff, they have it all.
Get the ecm dyno tuned after it's in the car.
