well after lots of research, reading and analyzing others combos (thanx to alot of folks on here and other forums), i have decided on my combo build and i am excited about it. i expect to complete in the next several months and figured i share with you all as others have.

well unlike most of you, maybe all of you lol, i have a truck. it is a low2001gmc duh.... anyway, while it has a nice 6.0 lq4 with 243s, the plan is to upgrade to an lq9 with ls3 heads and an ls2 portworks l92 intake.

since it is a budget build, ive had to be patient and wait for deals to come up slowly but surely. i bought a rebuilt lq9 shortblock off here with clevite bearings, mahle rings and arp rod bolts. i then purchased some used ls3 heads clean up milled .005 with lightweight valves of course and new psi 1511 springs. next i came across an ls2 portworks ported l92 intake. from my research, a stock l92 intake outflows a stock ls3 intake so even more should my ls2 portworks flow. cory at ls2portwworks looks to do awesome work and since i got a truck the l92 intake fits under my hood . i have decided i will have the heads milled another .010 for a total of .015 as recommended by spinmonster on corvette forum where i can raise my compression and minimally affect the ls3 heads flow. also i will run cometic 4.085 .040 gaskets to further raise compression to 11:1 while improving quench. i will also have the exhaust ports and bowls touched up to help exhaust flow but leave the intake ports completely unmolested as they already flow dramatically there. i also got me some sharp trunion upgraded l92 rocker arms. as for cam, this truck is my daily driver so i went conservative with a comp cams 228-232, 588-595, 114+4 i just bought off a member on here and am waiting on. i wanna shift at about 6400 and maintain a rev limiter of 67-6800 rpm since it is not a forged motor and has to be a reliable daily also so longevity plays a factor as well as budget. i will use my existing pacesetter 1 3/4 ceramic headers, march underdrive pulley, fast 92 cable driven tb, msd wires, etc. for tranny, i just a got a rebuilt with superior shift kit 4l80 with a new fti 3800 stall. rear end is an 8.6 gm truck with truetrac posi and 4.11s. got some caltracs also.

hope you all dont bash me and mind having a truck guy post up on here but i am thankful to all i have learned from on here, i am excited and wish to share and give back to this great website community.

any ideas, tips or advice are always welcomed as long as sincere and not jerks about it as i have seen some folks.

good luck with you all's projects... rob

Seems like a nice build man!

I'm doing something similar but opted to go ahead and move to a 370.. I had purchased an Lq9 but ended up cancelling and grabbing my 370.

Are you doing the port work on the exhaust side yourself?

I don't think many, if anyone will give you a hard time about running a truck. After all yours is good for more than going fast and looking good. Good luck on the build I'm gearing up for a 3rd gen bird ls 396 l92 head stroker build. Waiting for deals sucks!

Nice. Tech has really helped me too with my current LS3 build. Im on a budget too but luckily for us these new GM Gen IV motor make killer power with little mods and for way less money. Hope your build comes out great.

budget and youve got a vette??? its all good buddy, more power to you. i am expecting good things. ive done my homework and i expect it to pay off and be all i expect it to be. i wanted to keep lift under .600 just to be able to say i'm under .600 and kicking *** lol and make it easier on my springs since truck is my daily driver.

tell me about your combo as much as you can as i like to analyze everything i can and learn from others

My car is 10yrs old and I have a mortgage! Lol. I found a super low mileage L92 short block that I based my build on. Im keeping the bottom end stock since its really clean. I got LS3 heads from GMPP and a TSP cam, 231/236 .644/.615 114lsa. Aiming for high 10's. The car is right at about 3000lbs without a driver.

My mods so far
(motor should be installed this week):
GMPP LS3 heads
PRC .675 valve springs
Stock rockers
L92 block, DOD delete
Ported and shimmed GM LS6 oil pump
TSP 231/236 .641"/.615" 114lsa cam
TSP 1 3/4 headers
Short x-pipe with two Dynomax bullet mufflers dumping under car
3600 SS Yank
Built 4L65E w/3.42's

In case this helps, I posted a link to a pdf with all the torque specs for 6.2L and Gen IV motors.

i like the vette's blue color, looks really nice. sounds like a great combo there for a car weighing 3000 lbs . i would recommend some sharp trunion upgraded rockers though. thanx for sharing and best of luck

I wish the Vette in my avatar was mine. Thats the new Daytona Prototype that came out this year.

I will do a bearing upgrade very soon but with a correctly setup valvetrain they can still last a while. My friend is going on 3yrs with stock rockers on his 800hp G8 GXP.

low2001gmc

finally got motor in and getting the bugs worked out. darn fancy valve covers so i thought are leaking so having to put stock ones back on. check out pics of ls3 heads' exhaust ports i ported myself. hey at least i can say i did it myself . also pic of my 72 nova project that this motor was to go in and is now for sale.

a few more details on my project build. i painted intake to give it a slightly different look. check out the porting on the intake. in case you are wondering if it flexes on top, it does a little but i can live with it in exchange for the extra flow. i also painted my coil brackets to give them some detail. that exhaust port in pic was a lil off on the right side but i eventually got it perfect to how i wanted it before we installed heads. im proud of my porting.

babying still my new motor....lol....power feels good....seems like a lil less bottom end than with 243s but i wanted that trade off being that i have a truck with light rear and having traction issues even with caltracs. havent pushed it yet as far as top end which again is part of trade off i was after. the jury is still out on it to be fair. .

low2001gmc

iTrader: (148)

traction problems from standstill til past 75mph that i let off...lol...but now looking at cam swap to lunati 60512, 232-238, 599-601, 113+4 for increased top end espcially with my awesome fti 3800 stall and ls3 heads. cam has been ordered and next i hope for some tsp 1 7/8 headers

musclecarsrock68

Any new numbers with the new cam?
