Hi Dreasoner, sorry for the delay, this is my busy time of year. Yes it was a suck through set up, this is so much easier as you can run stock fuel pressure, with a blow through you have to run fancy pressure regulators to keep from blowing the fuel out of the carb. also everything would have to be sealed makeing work on the fuel system time consumeing. You are correct you will need a turbo with a wastegate to control pressure, in my experence a blow off is only needed with really big chargers where there is a large rotating mass that just keeps pumping.
for something neat on the street I will be looking for a small charger with wastegate,to make 12 to 15 pounds, with water injection, (may need 2 stages), leave the compression and cam alone. I will stay with a stock head gasket till everything is working good, a so so gasket can be very forgiving, and only takes a couple hours to replace, later maybe solid copper.
If you go much more you will need pistons, hard rods, probably a lot better crank, and a custom aluminum head. heads with siamese intake ports like the 235 are very hard to get each cylinder to fuel the same, also the valves off to the side don't flow for crap. Unless you are going to the salt flats, I don't think you need an intercooler, just use water injection.
