Will this cam do OK in a DD extended cab SS truck with these heads on the stock 6.0 block? 231/236 591/601 114+4lsa

Things I have for the build so far:

1 3/4 in OBX-R long tubes
stock 6.0L
HP Tuners Speed density tune
bare L92 heads, milled .030 to increase compression to around 11.2 if I've done my math right
Stainless Manley valves (2.16 and 1.59)
basic clean up on the ports (no resizing or shaping really, except for around the tops of the guides)
Crane dual springs, Ti retainlers, locks
Trailblazer stall 2600
stock 4.10 gears
Shorter 275/45/20 tires

I still haven't decided on carb style intake (for an old school look), or the stock L76 intake yet. Input?

Well, I just decided to go for the carb style intake. Richard's price was just to good to resist! I just love the old school look to much...

uhh... carb style intake in a truck.. you sure you wanna do that?

Car Craft made more tq at my 2600 RPM stall speed than the LQ9 makes stock at peak... I just don't know if I went to far with the cam choice or not to get similar results. If it ends up being a big deal, I can always sell it on Ebay...

I don't want to rain on your parade but going carb is a step back IMO. I am taking the old small block out of my car and putting in the LS setup because I wanted FI and the LS is such a great platform to begin with. If it is lack of color why not just get an LS6 intake and have it painted a color of your choice and use that.

There was a camaro in Hot Rod Magazine that had the intake painted silver/gray and it looked awsome. Makes me want to do mine this way.

I'm not going to actually run a carb... it's the carb style intake manifold drilled for fuel injection. I'll be running a DBW 90mm Trailblazer SS throttle body with a fabricated cowl induction tray to seal off to the hood.

the vic jr has lost a lot of low end on a lot of the radical builds, yours will be no difference. do yourself a favor and get an LS3 intake. its a little better than the aussie l76 setup. if you read in the external and advance forums youll find that the efi carb intake isnt really for you. btw, dont believe car rags... thats how you get pissed off when the real world comes knocking.

someday

thats a big cam for a heavy truck, i'd look for something around a 216/226... with the huge intake valve u don't need alot of intake duration

go with the carb intake.... it looks 100000000000x's better!

Those mags are wrong.... and so are you.

FYI, the Carb Intake does not match up to the LS3/L92 heads... it is much smaller on the port size.... if you gasket match it I am sure you will see as much as a 20rwhp gain. If someone wants to send me the extra cash to have the shop port my intake I will do a before and after dyno to hush the naysayers.

umm... single plane on a stock cube 6.0 with l92's is a BAD idea. hell most respected builders here will only use it on their fi/max effort builds, some even use the damn thing specifically kill low end. it is NOT a street intake

I got the cam used from a truck owner with a daily driven 408. The cam was to small for his build and he was still using the stock truck intake and heads... idled at 800 RPM and sounded barely larger than stock. Not a chance that it's to big, in general. Not to mention that it will still make more torque below my stall RPM than I make stock at peak. Single plane intakes on 347's make more HP than the FAST intake and match it's torque on the intake test I've seen. Do you have any dyno numbers comparing the single plane on 92's to stock L76/LS3?

The main questions here are: Is it to big for the L92 heads? Is the split big enough?

I did! Ordered it from WCCH and it should be here this week. I'll be using an old fashioned 14" round air cleaner and doing a speed density tune to ditch the MAF and elbow route though, so it will look even better IMHO.

How is the LS3 intake better than the L76 intake plse.

5.5 degrees of overlap... and 45.5 degree intake close.

it is not... it is the same darn thing.

there are small, small differences in the 2 according to lg. think newer l92 castings, same concept.

The cam will work well I believe. I like the Vic Jr. on the trucks with a 4bbl TB. Intake temps will be a bit higher, but not that much difference unless you let it sit and heat soak. Here are some pics of the one I did back earlier this year.

you really need at least a 10 degree split, and that is from the person who built my motor.

Thanks for that I thought that may have been the case.

Man I think you need to re-evaluate the cam choice. From what I have seen on a stock cube motor your gonna lose some low end on that choice, especially with an intake designed for higher rpm application. I know you think your gonna get it back with the stall, but smaller duration cams with a nice LSA are making gobs of torque on those heads with a holden style intake, without sacrificing too much usable horsepower. Heck, from 1600-3600 rpm a smaller cam, say 210/218 .531/.531 on a 114 makes equal AVERAGE hp to the cam your getting and 20 lb-ft more torque, and suprisingly averages 10 more hp and 10 more lb-ft than your cam from 3700-5900rpm (those numbers are compared with the small cam with a holden intake and your cam with a single plane intake, so very applicable to your situation). These are # your gonna notice much more on a DD, that a purpose built drag car, especially considering your putting it in a heavy truck and not a 3000 lb drag car. Torque is your friend. if your not into average #'s, it will make more peak torque and at a lower rpm than your bigger cam.

PS your cam with a holden intake will look better than your single plane at every rpm range, except the very top (ie 6000+). Now I don't know about you, but on a DD, I don't hit 6K+ very often. Also if your street racing, with a single plane plan on roll racing only. Just MHO.
