Re: LQ9 Build for 1972 Blazer

My LQ9 setup in my K/5 is all stock. It feels good/good enough for me. It's relatively fast and sounds great. With 4" lift springs, 35" tires and the top down I really don't feel the need for more speed. There's plenty of torque steer and a little twist when the setup downshifts and kicks in hard. The MagnaFlows scream when this happens.

It's actually a little unsettling when you're not prepared for it….

Re: LQ9 Build for 1972 Blazer

Pulled the trigger on the 6L80e transmission and 6.2L engine accessories today from RetroLS. Shawn gave me a little bit of a price break so I'm satisfied with the deal we made. Got a ton of work to do but at least I'm moving forward. To date here is what I've got:

2009 LY6 Block (144,000 miles)
L92 Heads Cleaned, Valve Job, & Milled .015, PAC 1218 springs installed.
Mast Motorsports VVT HO cam
6l80e
ECM
Wiring Harness - Still need to send off to be modified....Seller recommended Speartech?
Pedal
Power Steering Bracket & Pump
Water Pump
AC Compressor
Alternator
Intake
Injectors
Fuel Rails
Throttle Body
Coil Packs w/Plug Wires
MAF

Next items on the list:
Send off harness for modication.....suggestions welcome?
Getting hydraulic lifters or Stock LS7 lifters....RetroLS recommended this since the heads were off.......what do you guys think.....worth the $150?
Cam Phaser Limiter Kit....Read I need this to ensure no interference between pistons & valves due to installing VVT cam?
Headers
Fuel Tank
Radiator
Dirty Dingo 67-72 4x4 LS Swap Crossmember
And the list will go on......I'll stop here tonight so I don't overwhelm myself!
