I would not do the upgraded 6 cyl unless it was a 250. for all the money you will spend upgrading a 200 you would be miles ahead with a 302.
thanks for all the input, but I feel like I was misunderstood. my mpg is perfectly fine right now, but I meant on a different motor I wanted good mpg with good amount of horses. but from a little more research I've found it would be best, and unique, to have a bad-a** inline 6. I'm thinking a new intake, 2 barrel carburetor, and headers. sound good?
You can't replace the intake on a "small block" straight 6, it's cast in as part of the head. The header and carb are good starting points, but will cost several hundred bucks unless you can score a good deal on used parts.
upgrading for more power means upgrading the drive train. power ain't free...you have to feed them ponies after you buy the parts to make them... after you build that 200 you might have the same power as a...stock 2V 302 for less money... as Ward said..."I would not do the upgraded 6 cyl unless it was a 250. for all the money you will spend upgrading a 200 you would be miles ahead with a 302." ...JMO...
