LS1 LS2 LS3 6.0L S-10 with CNC Lingenfelter heads and Comp LSR Cam

did you run the cam in,its really not good for the cam,being the high spring pressure and low engine speed,make you do exactly what the cam manufacturer suggest,you have a nice investment,good luck with it.

@inagod

Thanks?!?!?! Ive worked on LS engines, doing R&D work for 6 years. Im not your average garage mechanic.... 918s do not have much load.

Hey I was looking into Comp's LSR cams for my 5.3L. Anyway the one I was looking at was this: 54-455-11 215/223 .604/.610 112LSA

Its got headers, LS1 type intake mainfold, and some other random stuff done to it, would I just need Comp 918 springs, hardened push rods, and an injector upgrade to run this cam in it? The 5.3L is installed in a 69' C-10

Thanks

I love that cam. 918s will work, but the 926s are recommended according to the catalog. They make .080" & .105" wall pushrods, get .105" wall pushrods. Im also running FAST injectors. FAST make a truck intake, 102mm LSXRT. And they just put out the car version for cathedral port too, LSXR for LS1s.

[sweets10v8]

what oil pan and mounts are you running, im doing a similar swap righ now.

[sweets10v8]

Mine has the Silverado oil pan that comes on basically everything(4.8L/5.3L/6.0L). Im also running transdapt mounts. Although I would run currentperformance mounts if I could do it all over again. THey sit the engine lower and farther back.

[v8sten94]

have you tought or heard anything about the new brp / hedman mounts?

[ramdaspadhye]

Had it dynoed yet?

[sweets10v8]

Did 3 quick pulls just so I could get AFRs close. Ended up with a bad plug wire the first couple. Made something like 410rwhp. Just threw out 28 degrees of timing. At this point Im just enjoying driving it. Ill start tuning it soon!! I just setup everything for EFILive tonight!!

[sebast007]

Sounds great!

[sweets10v8]

I took part number 146-456-11 (single bolt core LS3 cam) and had them grind it onto a classic three bolt LS1 style core instead. So you have to custom order it, which they do for free.

Specs are 219/235 .607/.621 113+5

[ls6guy]

sounds great

[kclm7]

I love your truck! I had a red 2002 4.3 5-speed ZQ8 that looked just like it. I ordered it loaded with all options including the buckets. I would have loved to put in a LS2. I miss that truck. :-(

[tiresmokinV8]

Sounds great man , Get that front end back on and hit the track.
