hey all, new to the forum and have a very important question. today i bought what the selller had advertised as a sc300. the 2jzge engine checks out fine and everything. i take the car to my mechanic to do a routine maintanance to make sure everything is okay. my mechanic tells me that there are a few things missing. upon futher inspection, under the the hood it in fact says 1uzfe, so im guessing it was a 400 and the guy swapped the 2jzge in the car and sold it as a 300. question, is the block different between the 1uzfe and the 2jzge? i just wanna know if he did a complete swap and not half !Removed! and only did a head swap. thankssss guyss hooefully ill put up pics soon!!!!
