At that point I would cut my losses with that build and go for something different.
How about a small block, with a nice set of twin turbos and fuel injection??? Or you can buy my 540 off me and ill build the TTSB
Sorry to see that, I hate seeing other peoples carnage. For me, its just a chance for a new beginning. I get so side tracked that by the time I am close to finishing a project I am ready for something new any how.
