Got some results for my recent build. Im pretty happy with it for as little money as I have in the motor. (Less than $1800)

6.0L iron block
LS2 pistons and rods w/ARP2000's, flycut .050" intake only
Stock L92 heads, milled .020", Brian Tooley springs, ARP head bolts
G5X3 112
LS3 intake, rails, 92mm Ebay TB, Siemens Deka 60lb injectors (for future endeavors)
SLP lid, speed density tuned
Edelbrock 1 3/4" -1 7/8" headers
mufflex ORY
stock 10bolt with 3.73 gear
LS7 clutch kit
Tuned by Bluecat - Phil Smith

Made 446 rwhp / 405 rwtq

The graph below shows the difference in the stock LS1 with bolt ons and my new 6.0L. I had the SLP lid, LS7 clutch, Edelbrock headers, mufflex ORY, and a TSP rumbler catback, and 3.73 gear on the car for both dyno runs. These runs are both SAE and are corrected. Compression on the new motor should be in the 10.5:1 to 10.7:1 range. The fuel pump is weak, possibly the stock 2001 pump since this car was bone stock when I got it a year and a half ago...even still had the stock air lid and silencer setup. I have a new pump ordered and may pick up a few ponies...during tuning the pump was sufficient to keep the car at a decently safe place, but upon 3 straight attempts to add fuel, we realized the pump was getting weak and we could not get anymore fuel.

Solid numbers. Wonder how much more is in her if you would have gone around 11.5:1 compression?

Thats a good question...but I didnt want to mill too much off the heads seeing as I want to throw a D1 on this car in the future. Ive got another 6.0L block thats gonna get forged rods and pistons and a different cam for tge D1 setup and I want to use these heads.

I figured that was why you didn't go with a higher compression. Either way, those are some great numbers considering how little you have in it? To me, those builds intruige me more than the "high dollar" ones. Maybe that's because I'm poor.

I just think its killer you can get near LS7 performance for so cheap...and probably more dependable.

No doubt. My dream is to one day build something like this and throw it in a Fox Body.

Nice results bud, definately a good affordable combo! Nice gains over the ls1! Maybe ill see it around sometime since I live in huntington?

Thanks...yeah I'll be out and about on weekends...usually in Ashland, ky though.

Nice #'s. I've got the same cam on 114 in my car.

I got my Walbro 255 in the mail today...so hopefully when I get it in we can dyno again and see if it picks up any more. Phil tried to add fuel 3-4 times, but the pump was pushing all it could push. He said typically these heads like to be around 13:1 air/fuel...we were at 13.5:1 and thats all she could push. We created a slight intake restriction and it picked up 7 or 8 horses b/c in restricting the air flow, we made the car richer. So this is why we assume the pump is weak. I know for sure I'm not having injector issues...only using about half what those 60lb'ers will do.

Knowing how stingy Phils dyno is, these numbers are very impressive. He has quite possibly the stingiest Dyno Jet ever.

Ahh, his software got updated a couple years ago, and it actually reads more consistent now...just maybe a little on the lower end of the spectrum, especially for a dynojet. But thanks for the compliment...car feels really good and drives extremely well for a larger cam car.

I was wrong before...it wasnt Phil's software that got updated, it was his hardware (weather station)...so i guess it is still a little greedy!

Sorry for the dumb question, but what's the benefit in cutting only the intake side but not both or only the exhaust side?

The l92 heads have a massive 2.165 intake valve so ptv gets pretty tight. He prolly didnt need to cut exhaust if the cam didnt require it. Idk the specs on those cams tho

I thought that intake PTV was not nearly as crucial as exhaust PTV? I mean isn't the piston all the way at the bottom of the stroke when the intake valve is at it's highest lift?
