Hello, I just wanted to let everyone on this board about Karl Ellwein. For anyone who is not familer with him, he is a LT1 engine builder from Maryland. Back in april i burnt pistons in my 94TA, and someone on here reccomended Karl. I couldn't have asked for a better person to build my new 383 blower motor. Once the motor was built that was pretty much where his responsability should have ended barring an internal motor issue, but once my motor was installed, i was having some serious issues with what turned out to be opti and MAF harness. Karl drove 2 HRS one way with his diagnostic tools to help me figure out the problems and even helped me with the teardown and install of a new opti. He answers his phone everytime I call with questions and he does what he says he going to do. His website is www.ellweinengines.com. he has many different combinations to choose from. So for anyone looking for a new LT1 engine do not overlook Karl Ellwein, you won't be dissappointed
