What in there now is more than enough! I run a Standard lx101 in my dart sport 360. Its a hot little motor! 292 mopar purple shaft, 3.91's out back 850 thermoquad on a Victor 340 intake. 340 X-heads etc.. it's a mean machine. Doesn't miss a beat!!!
My Rb 500 started life with that ecu. Then I upgraded to MSD. So, when it failed and got towed home 2 months later, I put it all back and it's been that way for years now. I just keep a spare ECU and ballast with me as I do in my Ragtop.
