There is a 1965 Mustang Coupe for sale and I was wondering how fast do you think it would go?
Answer #1 is right . That must be anew engine because in 65 the straight 6 cyl. wes 240 cubic inck, and the V-8 was a 289. Now as far as your question about performance and speed it depends on what we do to it. Being pulled behind a 72 vega i'd say 20 mph 25 if your lucky. I have a 4 bolt main boss 351 cleveland with ported and polished heads, double roller timing chain, good rods, 10.5-1 flat tops or 13-1 dome pistons, roller cam ,roller rockers, 21/4" headman headers, Holley 750 double pumper carb, vertex mag, and strip dominator aluminum intake, Titanium valves with fat locks. Lets put that in and see, I also have an old 460 we could build or use my cousins 468 small block rodeck. It is built right and has the best new desigh 8-71 huffer on top runnung about 28 percent overdrive. We have a lot of options to make it go fast so, just tell me how much money do you want to spend? Of coarse wewill probably need to use my narrowed aluminum tube dana 60 rear end with posi and 5.88's Know a fella that used to make carbon fiber parts for airplanes and am sure he could mold a pair of wings on for ya cause when I get done building it for ya it will flat as_ FLY
