Thread: Rebuild 231 or by 350

    I like the V6 that is my car a 77 Skylark but stock its only a 105 hp, my Ford Escort has more, but I have been checking on items to do a rebuild and hop ups, I have found headers and rebuild kit but not much else, so I don't know if it will have performance enough that I can get from a 350, and with the price of gas do you think I would end up with better mileage from the 231 or the 350, since it will take less to get the car moving with a 350 then it would with the 231. I really need some input...I want to get started doing one or the other.

    you first need to tell yourself whether or not you want gas mileage, or power. are you doing highway miles, or mostly running around impressing the chicks at the local dairy queen? Know what I mean? I personally would go with the 350, just cause it has a little more umph for the buck. But then again, you can't really price things out for Buicks, cause they're all over priced to begin with. I was toying around with putting a chevy in my 71 skylark just because I could get 500 hp. for the price of 350 hp out of a buick block. I decided to just stick with the buick for little to no reasons worth mentioning. Hope it helps I guess.

    Being as you are asking the question, I would feel that your probably not really in love with the 350 idea at any cost. So I would suggest serious consideration to just "dolling" up the 231. A few mods will probably make you happy, and if you do them right, you will even get better gas milage!

    If we can assume that the V6 is ready for a rebuild anyway, go for high comp pistons, a street cam from someone like comp, crane or isky, and the normal bearings etc., and you can wake it up quite nicely.
    If you are prepared to do the work and spend the cash, a properly prepared 350 is the way to go - but bear in mind you will be doing a lot of work and spending quite a bit of cash!!
    Either way, you can't lose really, can you?
    People to speak to for parts kits? Try PAW, Speed-o-motive, Summit Racing, or you can trawl the web and find individual parts possibly cheaper
    Best of luck,

    I appreciate your suggestions, I in a way your right I don't want to go through the hassle of getting another motor, I like the V6 it just needs some umph, it has nothing off the line but on the freeway it runs like nobodies business. The motor has 90+ thousand miles and its doe for build, and I have looked on the web for parts but its been a struggle to find 231 specific parst. Maybe I will just have to go to my local shop and see if they can help me on getting some performance. I do like milage..and the way the price of gas is going...I want to keep it...thanks again.

    I'm a bit old for the Dairy Queen scene and I am sure my wife would not like me checking out sceniory.

    One more thing, the car has Air conditioning, but doesn't produce much on the cold side, I think its a fre-on(sorry no spell check) type system, am I still able to get it recharged and if not what would it take to make it compliant with todays type. Would I need to just change one thing or the whole system to make it work?

    Don,
    Speed-o-Motive are in California (San Diego, I think), so at least they are in the same state. If you phone them they are very helpful, and will let you select the parts to put a kit together, I think a basic master kit to suit a 231 is about $350 - 400, with pistons, rings, bearings, gaskets, and cam etc., so they are certainly not too expensive. I bought a kit for a 383 Chrysler from them a long time ago, & if their service is still the same you won't be disappointed.
    Best of luck,
    Malc

    Well gents, I appreciate all your info, but at the moment I have a new problem. The motor over heated, darn gauge didn't work.....well know when I start the engine, its running really rough. I would like to know your opinions of what is wrong and if it means taking the engine apart, then I guess now is a good time as any for the rebuild. Oh by the way I didn't notice any water in the oil, but I am not sure exactly what it would look like in the first place.
