All depends on the Dyno. He also said he had bolts and a custom tune.

Doesn't seem far off

I am starting to gather parts for the AFM delete on my 2007 and a cam swap will be one, gears and converter will happen as well.

I'd like to compile everyone's experiences with small cams in the 220 and below range. I know the Isky 212 and Comp HR265 are both popular and effective, but what else? I've considered a custom grind for my setup but honestly don't think this truck warrants that much thought and BS LOL, it's my wife's DD.

Please list the truck/engine/converter/gears/tire setup yore running with these camshafts and as much information as possible about powerband, towing etc that you can include. I want something with a tiny bit of sound, good low/mid power and easy tuning/driving. It'll have a 3000 stall and 4.10's turning 33x12.50x20's they're pretty heavy, aside from being tall... Anyway, let's hear what you've got...
The Isky's are all custom grinds. A 210/214, .532''/.532'' or 212/215, .561''/.566'' on a 108~109 would work pretty decent... The .532'' lift Isky lobes have a shorter seat to seat number and make a little more low end tq.

The tq is hard for people to believe especially without a dyno chart. I think the throttle body spacer and custom 3" true dual with 2 x pipes help squeez out the extra 20ish tq. I saw a stock c5 with just a throttle body spacer gain 8 rwhp and 7 rwtq. No lie that's why I bought one haha best up grade per $$$

and for somebody to believe a throttle body spacer helps power............

it works great on carbed motors where it gives the fuel more time and room to atomize.. but when all it does it space the throttle body further forward on our trucks





Im running the Isky 215 in my LQ4 and love it. nice to pull a loaded trailer and not have to drop to third pulling hills.

Got the Isky 214-220? im thinking hard about putting in the Tahoe

The only time a spacer works on our trucks is if you drill and tap it for giggle gas.

Should have stuck with a 5.3, he makes more torque than I do.

It is the spiral effect. It applies to the theory of boost from turbos and superchargers. Directional spinning of the air rapidly to creating more air pressure. The throttle body spacer spins the air's direction just enough to make a slightly more combustible explosion in the chambers 5+hp/tq. The stock heads even have ramps on one side of the intake tunnels for a spiral effect.

Just my .02 cents most people think they are stupid and a waste of $100 is see it as the same gain from porting your stock 78mm throttle body or using premium vs 87

Get the VHP cam haha
