Good question for all. For me, just the bigger brakes and headers and I'm stopping........ha, ha. Seriously, I'm going to slow down on mods and concentrating to retirement savings.

Drove into work today. Even with .425" intake cams, when running right, LT5 runs really smooth. I didn't go too crazy and kept it below 4000 rpm.

Check out that oil pressure!

When oil temp is at 197 the gauge says 38 psi. This reading is with Mobil 1, 10-30.

Probably this is no big deal to most. However, having endured not knowing why my pressure was like 12 psi at idle, and more importantly, wondering if the low pressure was damaging the motor for 8 months, this is a big deal for me.

Lookin good Yun!!!!!.....break it in right and bring it back to me to do the oil change and oil analysis !!!

For sure! How about check for detonation per Marc's procedure using Tech 1 and some data acquisition every 1000 rpm so that I can turn to Marc to touch up my PROM?

I think it would also be cool to run some traces with EASE and send them off to Marc if you are going to do a chip reburn

I have it on an old laptop if you'd like to give that a try

I would before you dyno it and even get a wide band 02 installed to see what WOT AF ratio is doing for you. they are cheap!!

we should do a wazzooo tune on this bad boy.

If we pool our $$ we can afford the gear and then learn together some tweaking

fun winter project!!!

congrats on getting the "black beast from the east" back on the road and help usher in the era of a low $$ LT5 builds!! the 380 is a fantastic combo using the affordable offset stock crank and I think with solid intake and injector housing porting this combo will see over 500 at the tire which is a really good goal.

LPE LSV 36k (includes brakes and B&B, headers ect...) - 508 hp

Secondchance stroker lop a HUGE chunk off that price tag. - 500+ HP

I love my LSV but I sure wouldn't want to pay for it that build!!! (thanks Larry RIP)

I'm very impressed with what the Wazzooo boys have done

along the lines of poor mans power (pardon the hi jack)

I'll send some pics of my lastest "poor mans toy"

a TT 4.8 LS iron block with forged wiseco pistons, gen IV stock floating pin rods, stock crank, head studs, twin t04 turbos, 127 lb injectors, haltech ECM target is 1k hp at the tire without twisting it up over 6500

ok, r u sitting down short block cost ($1230 at lloyds) bought a used engine for $2300 with the turbos & stuff and freshened it up (had a bent rod and piston skirt issue). guy was nice enough to give me another 4.8 too!! I'll be building that one next for a bit more lunati forged 4.0 crank, rods, and wiseco pistons with AFR 225 heads to update the Z06 TTix TT (800 at the tire will only scare you for so long, need another 200, it's chasing the dragon I know but I like dragon rides

very happy with the results and cost. I hope to put this beast in a 68 vert vette as the current 350 is a bit below my clearly jaded standards (anything less than 400 at the tire feels slow now :<)

boostamuv!! maybe we can do a Wazoo TT ZR-1 someday. if I can talk robert into welding up those stock manifolds, some nice ball bearing billet wheel turbos LPE style, and a megasquirt doing "secondary only control" I'd really also like to do a cross ram intake with two fuel rails, one for pump gas and then the megasquirt controlling a separate fuel system to bring on some big doggie 80 lbs injectors running meth.

also like to go coil on plug at the same time and the megasquirt can handle the ignition chores with just a crank trigger. I'll live without the fuel range estimates and the security system :> I think the raptor megasquirt thing may have died off but I might be able to talk Phil out of his prototype or at least get corey to do me another one :>

I hope to do this someday right after I sell both kidneys and an arm

The Megasquirt guys (www.diyautotune.com) are local (Suwanee, GA) and I hear they are very close to offering engine management computers for the LT-5. They told me recently they just need to test the last firmware version. As you say, it can control secondary butterflies/injectors, coil-on-plugs and more. That's pretty great news, not only for folks wanting to modify, but also considering the lack of GM computers available if one goes bad.

it is the $2000+ price that bugs me though.. if ti eliminated the ICM or had option to run something other than our ICM for $2000+ then that different

our ECMS can still be repaired for way less than the cost for the new ECM

Hey, Ron,

Now that #256 is running again, I'll be at Cars and Coffee this Saturday. We can talk about best option to record data and get it off to Marc.

Amount of money saved - no doubt! Holding and oiling pistons and sliding them into each sleeves - priceless!
