Cheapest way to built a 300-350hp small block

You will have no problem building the motor for under 1000 but the swap alone gets pricey. I am not sure if it is necessary but I put a new radiator in mine as well which you could get used for cheap I guess. You also may need to upgrade the torsion bars or springs. I wish I could recall everything I had to buy but its been a while and all the papers from the swap are back at home. I would approach it as two builds almost. Build your motor then save some money for the swap. Also since your going to get a new transmission I personally would just cough up the few extra bucks for a good converter. I have the MP .484 cam in my 360 and my converter really helped it out a lot. Good luck and check for parts on here daily.
