    Quest for a good street h/c package

    I'm shopping around for a good head/cam setup for my WS6. I don't plan to order anything immediately, but plan to take a month or so to decide for sure what to buy, then order in August.

    My WS6 is a daily driver, so I want to maintain decent vacuum and idle. (My current mods are: Bassani true duals, Pacesetter LTs, 3500 stall & supercooler, P&P TB, SLP lid) I do like a slightly choppy idle, but not anything that is going to die out on me at a stoplight.

    Heads are going to be the first decision, then a cam to match them. What are the best head options out there for a LS1 (and how much $$$ do they run)?

    I drive my SS daily and here is my setup. Ls6 Stage 2 patriot performance heads, Ls1 Speed Inc SI3 cam 224/224 .581 lift lsa 114, and a Ls6 intake. My other mods are just like yours headers etc... Parts I'd recommend blueprinted oil pump and arp studs/bolts both are not a must have, but both are cheap insurance. Call Speed Inc they normally have a head and cam special. Here is the number 866-571-SPEED.

    I've got TSP's 228R LSA 114 cam and the only time i have problems with it dying is when i'm running my a/c but it only happens a few times a week.

    Did you get a tune from TSP with it?

    Look at the PRC stuff from Texas Speed and Performance aka TSP. They offer excellent flow/velocity for very little money. By far the best bang for the buck! I got my heads/cam package from them, which included everything I needed - a pair of complete heads, cam, pushrods, all gaskets, bolts, lifters, oil pump for $2000.

    As long as the car is properly tuned, many "big" cams will drive fine. My MS4 (a TSP grind), which is considered a fairly big cam by most, has nearly identical driveability as my old 222/222 little baby cam did. Idle is choppy, but stable, and hasn't stalled since the tune. Vacuum issues are non-existant with most of the stuff for the LS1 - you can get away with more on todays grinds than your typical SB of years ago. At least get something with 230+ duration, as the smaller cams WILL leave you wanting more very soon!

    Did you get the tune from TSP too? If so, did you have to tune it much afterward? I have HPTuners, but am fairly new to it. I've changed tire sizes and copied high performance tables, but that's all I really know so far. I'll probably get a dyno tune after the h/c package by a pro, since I don't plan on any further upgrades to the motor for a long time. I've tuned many old carbed motors for big cams, but am not very familiar with the newer computer controlled motors...
