Thanks for the information!
I found this big turbocharger that is normally used for trucks, busses etc. with engines ranging from 360cui to 650cui.
Do you think this might be a better choice (for a single turbo setup of course)?
My consideration was to use two smaller turbos to reduce turbo lag. On the other hand the 302 has plenty of low end torque naturally aspirated (compared to the small turbocharged four- and six cylinder engines around), so the bigger turbo might be better, right?
