General Questions????

[cyebo@xxxx]

Hey fellow Gremlinlovers. I have a few questions for you all. I am 
looking at buying a 304 for my Gremlin, actually its a complete 73 
gremlin, but the motor runs but will need a rebuild. My questions are.
1. What cc are the cylinder heads?
2. What type of transmission is in the car, its an automatic?
3. Where is the best place to buy parts or deals in AMC?
4. Is the 304,390,401 all small blocks and did AMC make a big block?
5. Finally, The rear end is a model#20, He said for V8 cars. Did they 
all come out with 4.10 gears? And are they very strong?
Thanks for all your help. GREMLINMAN
