1970 CUDA - 6.4L GEN III Engine SWAP - WOT Issues

I'd start with Bouchillon, and talk to Randy. They have always had good customer service, and may know what it is. One of the sensors may be bad around the throttle body, MAF, TPS, etc. Good luck...and you have a nice Cuda!

Thanks for your help! Yes, I'm talking with Randy and he allways give us good support. In the meantime, I posted this thread to have additional ideas.
