What is max rpm? What type of block? What type of pistons? What type of rods? What is the cam? What type of heads? What type springs

[@LS1FREEK]

7000rpm, stock gen4 6.0 iron block, stock LQ4 dish pistons, stock gen4 rods, 220/224 112 lsa cam, stock untouched 317 heads, BTR platinum dual springs.

[@ericperry4934]

So you are running a ly6? . Or ly6 block, with ly6 rods, lq4 pistons? Or lq4 block, pistons and crank, with ly6 gen4 rods? Is it a 24x or 58x? What type of trans?

[@LS1FREEK]

@@ericperry4934 It's an LY6 block, crank, rods and pistons. (Same as late model LQ4 2004.5 to 2006, other than LY6 has valve reliefs in the pistons, slight differences in the block and 58x reluctor) I just swapped a 24x reluctor onto the crank. Heads are from a 2003 LQ4.

[@bigwater52]

Curious since this is a year old now or so. How has it held up

[@LS1FREEK]

Engine is still going strong lol, actually fixing to make another video

[@bigwater52]

Mines got a little noise and iffy oil psi. But I’m gonna pill it till i quit it

[@ericperry4934]

Type of maim studs? Did you line hone?

[@LS1FREEK]

I've turned it up a bit since this video lol, but it's bone stock, only thing that's changed in the bottom end is new GM rod bolts after I took the rod caps off to inspect

[@ignaci0musik]

One day my obs will be a bad ass as yours

[@chipturd55]

Why does the light keep ahirting ofd

[@LS1FREEK]

It has a gravity activated switch, when the truck rocks it messes with the switch lol

[@tysonmoran2172]

Did you gap the rings?

[@LS1FREEK]

Nope, 120k mile engine

[@TJSpike]

So your probably running like a 585 lift cam i guess, but what size are the turbos?

[@LS1FREEK]

It had VSR 6766 turbos

[@ericperry4934]

What type of trans a d trans mods? What was the trans donor car?

[@LS1FREEK]

2002 Silverado 2500 with a 6.0L, 4L80e. It has better clutches, some billet shafts, and a CK Performance trans brake valve body

[@Tookoff]

Would you recommend these turbos or twin 7875s for an eighth mile built 5.3 with a glide?

[@LS1FREEK]

Check out my later videos where I swap these out for TDI s366 turbos, I recommend those. The twin 7875 will work but thats alot of turbo for a 5.3 to spool.

[@Tookoff]

@@LS1FREEK thanks man

[@701garage]

How do you like the dyno so far?

I love it, it does seem to read a bit lower than others but it works awesome to tune on. Truck picked up 28rwhp going from 12 degrees to 13. Its nice to know

@@LS1FREEK I used to have one, Now I have a Prohub. The roller dyno reads about 15-18% lower than a dynojet. I made custom math channels for that.
