Engine build help/ recommendations So this is my dilemma I’m looking to do a nitrous 6.0 (strictly track vehicle) build I know most people recommend nothing more than 200 on stock internals. Past that point forged rods and pistons is needed. That I know, but as far as which rods and pistons specifically i can’t find any direction to go. I have no issues doing the work myself I’ve had plenty back experience but it’s my first ls project. As far as parts I already have here’s a list
05 lq4.
4L80 shift kit and tci trans brake kit
E85 or 115oct
8.8 narrowed
Terminator x
317 heads
Ls7 head gaskets
BTR cam Specs: 233/248 .630"/.615" 111.5+2.5
BTR BRIAN TOOLEY RACING .645" SPRING KIT - STEEL RETAINER
CHROMOLY ONE PIECE PUSHRODS - 5/16" DIAMETER - .080 WALL THICKNESS - 7.400"
Holley single plane ego split intake
Holley 4150 1000cfm race throttle body
Nitrous express wet plate kit
My goal is low 6’s in a 2500-3000 pound car 28/10.5 slick
Local track is bare concrete road. Located in south fl
Any recommendations for a (kit) or even individual parts I appreciate it motor side ( wiseco,diamond,Mahle, k1). Hell even if you have converter or gearing recommendations that would help to. I don’t need any crazy expensive parts, I feel like these expectations to be a reasonably “budget/modest” build.
Thanks

I just had a 383 built for a good size shot back in May.
TSP stroker crank, TSP billet I beams, wiesco pistons and .200 thick wall tool steel wrist pins.
I would go bigger on the cam and bullet proof the valvetrain( dual springs, linkbar lifters, 3/8 pushrods) Stud everything. Ls9 gaskets.
open the rings up big, I'm at .028, .035. I was having issues with crankcase pressure on motor so I threw two -10 off each breather.
****** runs hard, loves the gas. 400 on 2 kits and planning on more

If you going to run a terminator then I would go to a dry kit vs wet. I have sprayed 300 on hundreds of stock bottom ends and 400 a on a few over the years. If you do it in stages or progressive and the tune is good 2-300 shouldn't be an issue. 15 years ago my 99 camaro with cam only had a nitrous out dual stage plate with 150 in each stage at 3350lbs ran low 6's. I know if I would build that same car today I could run in the 5's with the same combo.

I’m try to figure out my builds to. I’ve got a aluminum 6.0 with summit pro rods and pistons all studded and trick flow as cast heads I had built for nitrous for my street car.But it spun number 1 rod bearing so I’m building it back and planned on putting it in my twin turbo no prep car,and building a gen 4 lq4 sbe to put in my street car with nitrous.I’m trying to decide if I need to just leave the aluminum motor like it was and leave it in my street car and build the lq4 for the turbo car.How much nitrous could I spray on the sbe?It is a 2 stage dry plate from ind solutions.I’ve heard the iron block is better for boost is why I second guessing putting it in my turbo car when I have both and rebuilding both right now.
