Awesome! Thanks for the info. I'm considering having team208 do my harness. I believe I can do the work but I don't have much free time. I have ordered headers, adapter pipes, and mounts from holley.
The next thing I will order is the flywheel adapter. I will be running a th350 I've read I could use a spacer on the hub of the converter and elongate the holes on the stock 5.3 dished flywheel. But I found a flywheel from advance adapters that has a spacer for the flywheel with longer bolts and I'm curious what everyone has used. I'd like to one day upgrade to a th400. It will be a performance based build so I want to use what will hold up to higher power one day.
I'm also curious if a th350 and th400 use the same converter bolt pattern so I could buy one flywheel and use it when I upgrade the trans in a couple years. Or weather I'll have to buy another.
