    Thanks phantom.... duly noted. I am probably pushing the limits of stress on 46 year old parts. T3 makes a very nice upgrade..... as I’ve said many times before, our cars are never really “done”. Have a great weekend. Jim

    I've never broken a front axle....... Don't know anyone that has either. Not sure why that popped up in my build thread, lol. I replaced my rear axles out of fear of breaking one of them at pace on track. Jim

    73E90B91-D37B-4D6F-B693-3F0C2FD8E735.MOV Tail end of one run..... just to get an idea about how hard it is to put power down on a relatively mild LS1 in a 2500 car. So much freakin fun.

    When the tire shop did a remount of my 255 tires they tore a bead.... so I switched from the Kuhmo V720 to the Bridgestone RE71R. It’s supposed to be a much better tire..... I’ll give my review after April race. Jim
  5. Impressive parts list. Your going to need to support that chassis with that power or you’ll tear/twist it up. Looking forward to your build.
  6. I’m running long nose R200 CLSD. pain in the butt axle conversion.... but happy with it now. 3.9 ratio works great for track and autoX but will top out pretty quick if you’re going for huge speed.

    Finished top 5 today. I have a couple of great videos but I’m such a techno dufus I can figure how to consistently create links to full videos. Is there a way to share my Facebook videos? Quick pic from the end of the day..... I’m really loving the the new suspension parts. Jim

    Such a clean and well thought out build, congrats. You may want to consider heat shielding your brake fluids too. Driving hard may boil your fluid and eliminate your brakes when you need them most. Just my .02. Jim

    Well kind of a bummer.... the 275's rub on the flares with casual driving. I'm confident they will be much worse under race conditions. I'm running the car really low for COG and don't currently have adjustable perches for ride height adjustments. Soooooo, I'm going back to the 255 40 17 until I can adjust ride height or may just run a second set of wheels-tires with A comp rubber that has sizing to fit my current set up. AutoX this Sunday, I'll post some video when I get the chance. Jim
  10. I ran a tap over the Z sending unit and threaded it into the LS1 head passenger side near the firewall.... works great with stock gauge. I found/learned this from the HBZ site. Just forget where. It may be in my build log. Hope that helps. Jim
  11. Just don’t forget your steam vent. I tapped my water pump. Jim

    Thanks... Will do , Jim

    It didn’t help that it was cold on race day..... much less grip in cold weather.

    Track specs from alignment sticky. -2.75 front camber with as much caster as I could get with tire rub (I forget off the top of my head) and -2 rear camber with 1/8 toe in. My car has never turned in better..... Picking good lines pays off well but a miss step is pretty unforgiving. I went for throttle stear and lost the back end.... more rubber/traction and I would have totally nailed the line and recovered. I have a habit of overdoing it and it stops being “fun” so I’m fighting the urge to put on A7’s with a second set of wheels. Heroic mechanical grip but I have corded a new set in one season and that’s a lot of coin for a bragging rights trophy.

    Currently running Khumo V720 200 tread 245 front and 255 rear..... Adding Falken RT615K+ 200 tread 275 40 17 to the rear soon.
