225 Rebuild from scratch
Look up Oregon cam grinders, the can get you a regrind for like 80 bucks in a nice grind. Way cheaper than a new cam, and send them your lifters and they will reface them good as new for like a buck a piece. That's about $100 saved right there. Draw through turbos are the easiest to do, just fanagle up the turbo to the stock intake (blow it straight down in for distribution equality) and mount the carb off the turbo intake via a "power elbow' or a 90. Keep 90 to intake as short and compact as possible as the turbo will chop up the atomization pretty good buT the longer it's in transit, the worse it will work. This crude method allows you to use a standard carb with no mods. Any other na build will really work better with a decked block, cut up to .100 off if you can. Turbo can use stock lo comp deck height. Use a J pipe (my Peesh pipe?) Off exhaust and rest turbo right on top or high as possible to get carb mounting access, like it was made there. A good Carter Cortez side draft would work great buy those are hard to find.
