I've put 2K miles on the 6.0L and starting to get bored with it already. It doesn't have the "punch" I was hoping it'd have. Still going to get it dyno'd tomorrow but wondering what would be the most cost effective way to gain more cubes. Take my 6.0L out over the winter and buy a stroker kit? Sell my short block and buy an assembled short block from a vendor? $1800 seems to be the going rate for a stroker kit. Or around $3k for a complete short block from texas speed. Decisions Decisions. I would reuse everything, even the camshaft, just increase the cubic inches. I want to see at least 400 ft lbs of TQ from idle up to 4500 RPM's. If I can't, then it wouldn't be worth the upgrade to me. I want big block torque out of this thing. If I stand on truck at 1500RPM's the tires won't break loose, if I stand on it at 4000RPM's then I can pitch the truck sideways for about 30-40 feet (1-2 seconds). Can I see some dyno charts from some of you 400 cubic inch or bigger guys that are naturally aspirated? Also anyone running a 220 or similar duration camshaft in a larger CID motor? Anyone ever build one of these for torque?

 

Kinda stinks that your dissappointed... Have you looked into supercharging it? I know you said that you want NA, but for where your wanting the TQ, a Magnacharger might be the answer... Just an idea, good luck on your search...

 

My old 402 with 228 230 cam some badass low end power. I wish there was a cam that would feel like that one did down low, and still pull like the new bigger cam pulls up top.

 

get a 572 and sell me your 6.0

 

Do you have any dyno charts to share?

 

LoL the keyword here is budget I know I can't have my cake and eat it too but every damn lsx motor I've built, tuned, or been in so far feels like riding a 2 stroke dirtbike to me. They all seem to go ok, then they really go and really really go. They just seem to have the powerband of a 2 stroke. What I'm missing is my 4,500 RPM lower power that a big block would typically have. I think my 6.0L would put up a good fight against my 454 above 4500RPM's don't get me wrong, but my 454 would rip it in half under that. Maybe I'm being un-realistic here. Kind of one of those things where I'm dreaming out loud but if I could keep the price reasonable I just may jump at it. Remember, I kept my 6.0L swap with cost of the headers to only $1,800 after jockeying parts around. That's everything included. If I could do the cubic inch jump for under $2,500 I just may jump at it. Hey, I'd even reuse my 218/224 cam

 

thunder runs a really small cam, of course he is boosted tho.

Dont think you could get away with a stall and cam swap. I mean i dont know how much you feel ur really "missing"

Weird how fast you get used to the power. After i got boosted I turned it up within two weeks.....

 

My opinion is use all of the parts you currently have, except with the stroker kit. I drove a poorly tuned 408 (partly my fault, partly due to an extreme faulse KR* issue, long story) around with a 212/218 cam in it for a bit. That thing had the torque you're looking for even not tuned in as it should have been. It was very torquey below 3000 and pulled to 6000 with no problem. Compression and cubes is going to get you what you want.

 

I know what you mean, it starts to feel soggy after a bit. Maybe I just need to be more realistic and convince myself that this is fine for a daily driver. I've driven so many big blocks in my life that I'm spoiled with the low end grunt they have. With my 454 for example, the rear tires will jitter and shutter (on the verge of breaking loose) in 3 of the 4 gears if you give it 1/4-1/2 throttle with any quick pedal movement. To get the same effect from the 6.0, you'd have to have the engine speed up around 4500RPM's or so. The 454 will do this under 2500 RPM's with ease. It's like driving a 2 stroke 500CC bike vs. a 650 cc 4 stroke bike. Remember, both trucks have manual transmissions, nothing I have has an auto.

 

You wouldn't happen to have any dyno charts from this truck you tuned, would you?
