Im looking to purchase a 1980 ramcharger that has a 360 in it. The engine is stock and is a great running engine and uses no oil. I am looking for a small block to put in my 70 'cuda to get me through the next couple years until I finish a house remodel. I was considering using some parts I have from a 340 that needs rebuilt on this engine. I have J heads with 2.02 valves that I would like to use if it will not lower the compression more than it already is. I also have a hughes engines whiplash cam that I would like to use. This cam is supposed to work great with low compression engines. I have a few 4 barrel intakes and an edelbrock 600 carb. Also have headers. Would these parts work okay on the engine? More importantly... would the heads be a good swap?
