I hear you Jim. But with 525 HP, the car's gonna get tore up anyway if you don't beef up the structure. You've had quite a few birds. Did any of them have tears in the quarter or have any body twist? I ripped the right rear torque box bolts loose in my 350/3 speed by 1972. I'm sure a more powerful setup will cause important damage in no time.
I'm still looking for a sturdy but not so surgical/invasive subframe connector that doesn't look like an iron bed frame stuck beneath the car. I hope to see the Hotchkis connectors in person before that decision needs to be made. I like the DSE kit except for it's surgical scars. Done well, it looks like a factory job.
