Yes, factory V-8 Gremlins are very hard to find, and very desirable in AMC circles. AMC had poor rust protection up till '78, so rust is very common on them. The last year of 304 Gremlin production only amounted to 800+ units. The 304 Gremlins could run pretty well, all they needed was a bit more cam and a 4V. My Hornet has the stock cam and a 4V and it's pretty damn quick. Once massaged, 304 Grems (3,000+Lbs) were quick.
Randall AMC in Mesa, Az used to put 401s of any build state you wanted in Gremlins and Hornets. And let me tell you, if you're lined up next to a 401 powered Grem/Hornet, you'd better have something under your hood. Because these thing would lay down the boogie on street tires. I saw a 401 powered Grem with slicks run in Ca., and it was a nasty car, with no go go juice to boot..............Los
