Truck: 05 Crew Cab 2wd. Heavy 22" wheels. 3.73 gears

After installing the wheels it was a total dog off the line so I put in a Trailblazer TC (2600 stall) which made all the difference back, maybe more.

Engine: 116k, Hacked airbox with spectre filter and ebay tube, ported TB, mildly ported 243s milled .030 with LS3 springs. Dumped stock exhaust per the wife. Headers may come.

I drive the truck daily mostly highway, on roadtrips and occasionally may pull my wife's S-10 to the strip (couple hours each way)

I currently have an Edge programmer but that'll change once the heads and cam are installed.

I called Cam Motion and they recommended their 9.5cr Stage 2 cam. It just seems so small. I think they advertise 1400-4400rpm.

Granted its a heavy truck with heavy wheels and may sometimes pull a heavyish trailer but I mostly run highway speeds, I don't want a dog down low either.

I've got a friend with a RCSB with just intake and exhaust and he is currently testing that cam and said it feels much better, lots more low end.

Maybe thats what I need but I've been looking at the 212/218 and the 220r

Thoughts?

 

Trick flow 216/220 would be a great option especially for the price.

 

My brother had the same dilema a few weeks ago. '06 CCSB 5.3 with heavy 22" wheels, granted he has headers and 4.10 gears but no stall. Few shops recommended some cams in the high 22x range but I told him it's too much if he wants to keep it a DD.

I ordered him the 212/218 low lift cam and he has nothing but good things to say. His tuner even said it ran better than a RCSB 5.3 with 224/224 cam, no stall though. Truck has no dead spots and pulls hard to 6K. Highway MPG stayed the same but around town my bro can't keep his foot out of it.

The only thing we both don't like is that its not as choppy at idle. The other cam we looked at is the 214/218 from SDPC with more lift and lower LSA.

 

what brand 212/218 did you order?

 

I'm assuming Comp since you said low lift, I've heard some bad things recently about Comp cam failures.

I see that Lunati also has a 212/218 with lift in between high and low versions of the Comp cam.

 

Ive hurd the same thing about comp too.. go with lunati. I tnink they have alot better quality materails

 

All of those problems seem to have a common theme of dual springs.

 

True!! But do u wanna take that chance

 

What the source for the trailblazer converter?

 

Just a Trailblazer 4.2L i6 oem converter

warning, we tried it in a 94 Model and it does not fit the SBC
