I talked with Lt1.com about ac request also. I was told on dbw setup ac request doesn't need to be setup only dbc need that. My neighbor has dbw with no ac request.

I know that the pcm will automatically bump up the idle when it senses the load change but I think I need the AC request to turn the fans on and off. Your neighbor might have controls for his fans independent of the PCM?

LOL. I have enough bad influences on here myself. Its funny to find out I am one too.

Yes my neighbor has it setup independent from the pcm for ac fan control.

Not much progress on the build lately- mostly waiting for parts to come in. A few delays as my engine gets bumped at the shop for professional race team customers.

Block is nearly finished and ready to go. It got the works- it was hot tanked a few times to clean out the dexcool mess. Magnafluxed, sonic tested, bored and finish honed to piston size, align bored mains, cam journals align honed. Still need the front machined to fit the cam chain tensioner since they didn't come on truck engines (at least not on this LQ4). We're using all ARP fasteners.

Rotating assembly is forged Mahle pistons, forged callies crank and compstar rods. The short block is being set up to hold 1,000 hp all day long. Overkill for sure but will last forever pushing the planned 600 at the flywheel.









Intake is going to be a FAST 102 LSXRT truck intake (got a great deal on this shop mule) with most likely a Nick Williams throttle body.



The final balancing of the rotating assembly should be done by the end of next week. Then we're cc'ing the pistons so we can tell Advanced Induction what to finish mill the heads to. Then we'll check our valve clearance and get a cam grind figured out with comp cams. Should be around .640ish for lift.

None of this is happening fast but it should be worth the wait when its done.

I spent a few hours at the engine shop yesterday.

The crank got temporarily installed to cc the pistons. We were able to let the cylinder head shop know how much we wanted milled off to finish the heads to get our target static CR.



The reluctor wheel got installed (still needs to be welded on).





And I spent some time doing my rocker arm trunion upgrade (eliminates the factory needle bearings).



Before I left I also hung out a while and watched Rick do a balance on a rotating assembly. I knew the theory of it but haven't watched it being done before.

Thanks for sharing.. Some cool pics too

Awesome build!! Your progress makes me want to dive into my project!

How is "Blu's" heart transplant moving along ?

Other than that sexy new damper (another gratuitous pic below) showing up yesterday, not much to report. I am hoping I can pick up my cylinder heads this week. Advanced Induction lost a board on one of their machines and since they use all F1 spec stuff the replacement had to come from the other side of the Atlantic. That's got them behind a couple weeks.

When I have the heads we are going to get them on my short block and see what my true valve clearance is going to be (put a dial indicator on the top of the valve and see where it makes contact with a piston at tdc). Then we give comp cams a call and see what they come up with for a cam. Looking for 1.5 hp/ci which should be around 600 at the crank. As long as the torque is strong too- should be with the displacement.

Then it's final assembly and back to the shop for initial start, break-in and tune on one of the shop dynos. I'll be happy if it's fired within the next two months.

Thank you sir!

This motor should be able to breath well. Will be nice to see you putting it together.

Thanks Larry. I did the math this morning and should be able to get it on the dyno for startup, break-in and tuning before the end of summer.

Sounds like it took another turn of direction Look forward to watching the transformation

Still in the same direction, mostly, but decided to jump in the HOV lane to get there a lot faster. I am pretty tired of spending all this money on a truck that I have to push out of the garage when I want it to move! I want to get it to what I can call done for a while and just get my truck and garage space back.

Heads are finally done. I had Advanced Induction in Concord, NC give them the works with their 232cc Full CNC Port package with oversize 2.055" intake valves. BTR valvesprings and ti retainers finish it off.

What's your head CC and your gasket thickness and compression ratio going to be?
