I'm new to this site and wanted to ask a few cam questions. I am looking to buy a cam a TCI street fighter, and maybe a set of LS6 CNC heads. I curently have a westers 93/100 hot tune pcm, eldelbrock shorty headers, true dual 40 series flowmasters, 180 t-stat, msd 8.5 wires and ngk plugs. What I want to know is what would be the best cam to go with on my current mods and the TCI stall and heads. I would like to get a real nice increase in the mid to upper (even lower to mid would be fine) range of the rpm band and also a rough idle out of the cam (just love the sound of a good rough idle cam). Any help would be great, any specs and the best place to buy from. Thanks Erik

 

also maybe a head recomendation, should I buy heads or try and have mine reworked? If I should buy them what should I go with?

 

I would go with the .212/.218 .522/.529 from Competion Cams. As for heads, as expensive as heads are for these motors, you would be better off getting a 6.0L motor for the same price as a good set of heads. I just think that would give you a better platform to build. A cam swap (cam, springs, pushrods, gaskets) is gonna be in the $500 range....at least....and that's assuming you go with some used Z06 springs and reuse your pushrods and do the job yourself! Combine that with $1000-$2000 for a set of heads and as you can see you've laid out some cash. I bought a new 6.0L for $1600, a cam, 918springs, hardened pushrods, gaskets, waterpump, Titanium retainers (used), an underdrive pulley, MSD plug wires, and Iridium sparkplugs for a total of around $2500. I would expect to make more power then a heads/cam 4.8, and still have more room to grow down the road. Just my .02, and if you do decide to stick with the 4.8, a cam and converter will make a nice starting point....ask 01THUNDER, his little 4.8 is ROCKIN'!

 

I would agree with BADMOFO on 212/218.
unless you can wait a few weeks and then I should have some dyno numbers out of the 4.8L with the new setup.
right now I dont have any numbers for gains with the cam I went with but I hope to post some good numbers soon.
picked up 2 mph, and 2/10 of a sec with out a tune, just enough tuning to get it running and drivable.

Im by no means able to hang with the "big guys" but I can hold my own, and surprise a few people. I would say the truck is about average for all motor

 

where did you buy the 6.0L at?

 

I as you know by now wish my truck was as fast as yours, I am Tama1 from MCT

 

Jon Barrett Hot Rod engines....a guy named Jorge will set you straight. I saw them on EBAY originally, then called them and bought it out right. They have them on EBAY from time to time. Their user name on EBAY is arielperformance.

 

I still think the 212/218 low lift on a 112 would be a nice rowdy little torque-maker. I'd imagine that cam would fit well in any of the truck platforms.

If you want a stump pulling cam, the small Comp 206/212 should do that for you. It's on a 112LSA, and might make a little noise at idle.

If you want a proven street cam, the 212/218 low lift with the 114LSA.

Then there is the 216/220 114... which has made up around 400hp on H/C/bolt-on LS1's. I think if you're looking at that range of duration, you might want to go for a quicker ramped cam like the TR220, or maybe the TSP220 to save some lowend and make some power under the curve.

A lot of it has to do with what you do with your truck (street/strip, commute, tow), and what sized stall you're running.

Oh yeah, and welcome to the site.

 

I am wanting to make a street/strip truck so I really dont want to lose to much lowend.

 

I personally think the 212/218 would be the best one to check out... but I'm kind of conservative. If you run searches in this section for that cam, you'll be busy for the next 12 hours.
