Hey guys! Well purchased and Edelbrock Performer to go along with my Edelbrock AVS2 650cfm electric choke carb for my 273 just to spice things up a bit. Had the time this weekend to go ahead and swap those out and everything was going well until I noticed once I cleaned out the block to prep for installation I saw the cam….and the metal is basically chipping away. Looked closer at the cam and the west marks are insane and wow did it not look nice at all, at least in my eyes ha. I’ll make sure to get some pictures after I start the work. So basically my happy go lucky day turned into a not so lucky day and now I’m looking at replacing the cam. Now I referenced TMM’s 273 build and although I would love the Isky E4 the set matched with lifters and pushrods is just way over my budget unfortunately. So I was looking at the COMP Cam 270S kit with Lifters which is about $410. Mind you I’m not fully limited on budget but this engine will be a just pleasure cruiser until I start to build and finish the 360 I want in it. So I would like to keep the budget relatively low and then once the 360 is done and the 273 is out I can build her up as a secondary project. Since I am new to building engines I just don’t know where to start. I know I need camshaft, lifters, pushrods, rockers, and a timing set (I’m assuming because if it’s like anything else on this engine it’s going out). I just don’t know what pushrods go well or what rockers to choose. Should I stick with single or move to double for the timing set? It also seems like the pushrods installed are hydraulic even though the rockers installed are mechanical? I could be wrong but I’ll attach a picture maybe you guys can tell. I just wanted to see if I could get suggestions from everyone on a good setup with the cam I listed above. I’ll post questions/options below that I’m thinking and remember I am very new as far as experience. I could tell you how a turbine engine works since I’m around them everyday but automotive engines are a new realm for me so I’m still learning haha Thanks guys!
