I have a72 gremlin with a 304, planning to put a 360 in it. I have runSBC's in novas years ago. but I think if you are going to run a gremlin I think you should keep it all AMC-I think the whole point of owning a AMC is to be different than everybody else. In other words, if you want a SMC, run a chevy. Just my 2 cents worth! Right Bart? Tom 72 GremlinX
