I have two 292 to choose from; One from a 1964 Truck and one from a 1975. Is there any information I should know to help choose which is best for me. I currently have a 1978 Chevy Truck (dailey driver)with a 250 engine Clifford intake, headders, Holly 390 4bbl and a 700r4 trans. I use this as my daily driver and very rarely do any towing. As of now I am only planning on putting a better than stock cam in it (Any suggestions as to which one?). Thanks
