    Rear end alignment issue

    I have alot of experience with removing and reinstalling rears from the G-bodies we have. I have found it easiest to put the frame on jack stands near the lower front arm bolt, support the diff with a jack, remove the lower shock mount, drop the rear enough to remove the springs. At this point...

    That gear change will feel like you added 70-100hp. You'll be amazed. Let us know the before and after butt dyno results.

    radiator options for LS swap?

    For some peace of mind, I ran a stock MCSS radiator for two years with LS truck accessories. Plenty of street miles and 1/4 mile runs at 800-900whp. It worked just fine. But over 900 seemed to start getting hotter than I cared for on the return road. For a NA motor, there is no need for much of...

    Save her

    I have an '80 Cutlass VIN tag and title - grab it for nothing and ship it to me. I can't believe it will cost that much to ship..................................to Upstate NY (shrug)

    Gear ratio help

    I haven't seen what size tire you're using. If short, stockish size tires, then the 3.08 is what you should use for what you're describing ^^^^. If money is tight, leave the open diff - one wheel peel isn't the end of the world.

    radiator options for LS swap?

    There are almost an infinite amount of options. Your choice depends on how you want it to look aesthetically and/or your budget. The budget option is to use truck accessories from the junkyard/donor truck motor and a stock radiator that IS either new or in good condition. That allows you to use...

    BUILD THREAD 86 GP 2+2~Blown 6.0

    Take the smaller pulley with you - trust me. Your description of the fueling makes sense for a larger cam. Just keep it above 1900-2000 when cruising (unless you’re picking up grandma from church to head to the grocery store)

    ‘25 season

    2nd hit of the season sketchy prep. It went downhill from there as the track went downhill.

    Family 1st is good rule, and overbuilding is as well.

    BUILD THREAD 84 Regal back half/caged/mini tubbed lq4/4l80e build

    The difference between a 3.42 and 3.55 will barely be noticeable. I wouldn’t consider finding a rear that would be happy with a 26 and 29” tire mainly because there isn’t one. Let’s back up, what cam are you using? Headers or stock manifolds? Stock compression between 9:1-10:1? I read back...

    BUILD THREAD 84 Regal back half/caged/mini tubbed lq4/4l80e build

    3.90 with a 26” tire will suck. 3.73 at a minimum. 3.55/3.42 would work fine. 3.73 with a 28” tire turns 2700 rpm’s at 65-70.’
