Been getting serious about collecting parts for a 383 this winter. Was originally going to use my vortec heads but have done some reading on the topic and lots of folks in the car world are saying that vortecs will choke a stroker build. Any thoughts on this? I was looking at the dart iron eagle line and they seem to be reasonably priced but don't know if they would offer much of a gain if any at all.
I bought a 2005 Escalade ESV with this engine and I will tell you...it snatches 6000#s around like you wouldn't believe!!
Before you commit to a 383 from the old school stuff (which is great) consider the LS platform and the 6.0.

I called Marine Kinetics today. Bob was a huge help and I believe I will be having him grind me a custom cam and help me pick out my components. I only want to do this one more time so I'm gonna take my time and do my homework. Thanks for all the input guys. I will definitely be using a little bit of everybody's advice when I start doing this thing

Mine is going to be a side project for now, I don't want to put myself on a deadline and not have the funds to finish it by next spring. Once I have all of my parts collected I will take my current block apart and go from there, until then I'll keep riding the 350
