the 2bbl is GREAT, but IMO it's not worth the money unless you're sticking around with the cast head... I put $1500 into my cast iron head, for more air flow, porting and valves etc... wish i put that into the alum head for only $600 more and I would have had 50more hp...
Just something to think about but if it runs ok just put it in and run it. If you have a 200 now you are probably looking at a trans swap which will take money, planning and time. Then you could decide if you want to put money in your 74 head which is not the late 77-81 head many look for because it flows more (larger log) or look for a later one. That is how my whole 1970 250 engine swap ended up and now I have purchased a complete late 1979 250 engine to build when I can get to it but no rush.
what the guys taught me here (4 things) was that: 1st research was important and the 2nd & most important - application drives all the decisions on components, machining, etc (end goal). What I came to the automotive field w/ was a systems perspective so 3rd, 1 change 1 place will only wrk well if other prts of the system wrk well w/that. Finally, make all the decisions and stick w/them through out the build till completion (therefore if the research wuz incomplete ur ina lill trouble). Changing in the middle only makes a hodgepodge.
Anyway, those R ideas 4 me due to my lack of automotive theory, I'm a beginner in many ways. So experience is the best teacher. Give it a try, it's all just learning anyway. And U get a nice product outta it as well.
So, backin up: What is the application? DD? show car? strip bound? xx?
(I think it's a beginin project ride you'll do more research on while away & return to complete!)
8^0
BTW: this 4 prt plan totally leaves the $ question out, that's related to the research prt tho... ur ideal "dream" vehicle will B reduced by the sz a ur pocket book, 'course. Also - the research can't go on 4 ever, the project must start @ some point. These are 'balancing factors', eh? Money & time, money & time...

For the money, in order, I recommend:
1. Ignition - reuse the MSD, get new plugs, wires, cap, rotor. Upgrade to a duraspark $150
2. Carb - Autolite 2bbl on an adapter. Buy a used one, rebuild it. $150
3. Exhaust - used headers, duals (use a generic kit for a 66-67 Mustang) $450
4. If it's a 73 or later engine, use the 69-72 timing gears. The later engines have retarded cam timing to reduce NOx emissions, but lose a lot of power. $100
5. change the oil....

is that good or bad. Also here is some pics of the carb setup, and my car. http://s792.beta.photobucket.com/user/4 ... sort=3&o=0
