Still has a 400 in it and a gear vendor. Been running that since 2011 ish. I call it overdrive.... At least that's how I use it.

9's with stockish motor...... Motor had rods..... Other then that the motor was stock. Pistons, crank, cam, heads all stock. Had exergy injectors, 2 stock Lbz pumps (but may have only been fueling with 1), and 3 box stock 66's. Ran 9.79@142 at 4560lbs.

T stat housing.... I'm sure he would make more. But it will be costly, it's all by hand on a mill (no computer controlled stuff) so it's about an 8 hr job. We've discussed how much he would charge to make one, obviously if he made several it would save some money and time.

If your serious Lmk, send me a text or call and I'll set you up. It will be expensive.... Keep that in mind.

Not on this site. It's evolved so many times in the past 9 yrs it's hard to keep up. It has a stock LB7, turbo 400 and 9". Hole bunch of stuff In between that. Been driving it since 2009 with this lb7 and have over 50k miles on the car since then.

It's the car in my signature.

Glad to hear you're liking it. I'm still needing to build twins for mine to take advantage of that fast spooling turbo I've got...

Thanks for the feed back!!

Oh and this Dmax is bone stock..... With a stock s475 on it.

9 years on the same engine, runs high 9's, you can drive it home from the track doubtful any 9 second gasser with a big block could that and still be in one piece and a daily driver.....

Well my stock LB7 finally came out and got tore down. It never really failed, just stopped making more power. In early 2016 I started making upgrades to the motor and it never really responded. Modded the factory IHI turbo, added the S475, put in new injectors and earlier this year put in a 10mm exergy pump. All of this did nothing, in fact in our last outing it actually went slower............ significantly.

Guess we finally wore her out. Put approx. 60k miles on her (in the last 9 yrs) and hundreds of passes, never missed a beat. In fact if it wasn't for it "not going faster" after all the upgrades I probably would not have tore it down.

So this is what we found: valves leaking compression, cam gear pin bent ready to shear, reluctor hub pin bent ready to shear, couple injector cups leaking coolant causing coolant consumption, 4 hammered main bearings (smashed to shit!!) but don't think they actually spun.

So......... new stuff. Not doing a full build but am upgrading several components and replacing a bunch of parts. Heads, block, crank and cam all getting replaced with factory parts but the cam and crank are keyed. Balancer and flex plate are SCD and getting the rotating assembly balanced. Going with LBZ rods and cut LB7 pistons. New IHI 63.5 high boost turbo and a new S475 T6 1.32 atmo turbo. All the same fueling, 10mm pump, stock sticks and aeromotive fuel pump. I will upgrade the injectors down the road, just getting too pricey now with all the changes and upgrades.

Also going thru the tranny, converter and gear vendor........ these have all been torn down and are back together waiting for the motor to be done. Went with Reybestos blue clutches this time. I have never tried them before and have been running Red Eagle clutches this entire time. The reds worked, were cheap for rebuilds but feel I need to try something different, so here we go. All new clutches, steals and band (pretty normal rebuild after 10k miles or so. Converter had about 20k miles on it so had it gone thru and the gv needed a new clutch, sprag, annulus, plannet carrier and planet cam it had about 13k miles since last rebuild.

Now the car........... needs some work up front in the engine compartment area, crossmember, frame mounts and motor mounts all need attention. Then the exhaust needs to be tweaked for the new Atmo turbo. Then Interior, fronts seats are shot. Then tires, picked up a set of 315/60-15 ET Street Radial Pros this past weekend, hopefully they work out!! been wanting to try the pros out since they came out a couple years ago.

Whole bunch of changes and work. Hopefully the machine shop will finish up this week and I can start assembling the motor, make the changes to the turbo plumbing and get this thing running!! Fingers crossed that it actually makes the power its suppose to and holds together for awhile, we see soon enough!!
