I've spent 3 and a half thousand so far and mine isnt close to being done. This is with the first generation carburated small block 350 and a WC T5 5 speed. These were both rebuilt for 2k. If you add the bellhousing, clutch kit, master cylinder, and flywheel, you have at least 2 and a half thousand. The JTR kit was I think around 500. I got my intake and carb cheap for 70 (used). If you add all the other stuff you forget to budget like the shifter, fuel pump, fuel lines, ect. It adds up. LS1, in my opinion is pretty much out of the question until you have 7-8 grand. The LS1 and T56 alone can cost 3 i think. Correct me if im wrong.
