    Nice, Elkie's are always cool. I had a 72 and a 75; both great cars.

    Head stamp is 83417369, Hencho in Mexico. I believe these were used with gm crate engines and have 1.94" intakes and 1.50" exhaust.

    I really have no idea what the cam is other than its aftermarket and has a moderate lope at idle.

    Hope this helps and thanks for the suggestions on intakes.
    The head casting number is 33417369, 90-up...350...Gen.I.... Goodwrench crate motor,"Hecho en Mexico", 76cc
    With 76cc combustion chambers and the need to run this motor on 87 octane unleaded fuel, I'd bet the piston crowns are 10-12cc dishes and the static compression ratio is more like 8.5:1. Please do your part for humanity by removing the heads and smashing them with a sledgehammer so that some other lad down the line would not unsuspectingly try to use them on his hot rod.

    Added info

     



    There has been some discussion here regarding head stamp. Many people have said the the first number is a 3. I had three individuals look at my heads and also used a magnifying glass (moving up in years ya know) and it is diffently an 8. One person on the board indicated that they were good heads. This determination is beyond my knowledge. Just as a note, I've been running 91 octaine and plan on doing that as long as I can find it. I run it in all my Harley's so I'm used to buying it.

    After doing a lot of internet searching techinspector1 was right on the money as far as the heads go. They're not as bad as 305 and some 307 heads, but they're nothing to write home about. A good set of vortec's or aftermarket aluminum would be your best bet depending of what kind of power you have in mind.
    You can run 91 octane in that engine but all you're doing is throwing money down the toilet. It'll run just as well on 87, but it's your vehicle and your money.

    Ok, I get it. Being retired and money is slim, what is the most economical way to go? Bite the bullet and go new or would there be good options in a salvage yard? Is so what should I be looking for? Motor, year, head stamp? Keeping in mind this isn't a race car but would like to get 300hp out of it.

    Maybe you should check Summit and Jeggs. They usually have 300hp 350 crate engines on sale for $1500 or so. It would save a lot of hassle and leg work for you. Ok, I just checked. $1600 free shipping and a 3yr/100,000 mile warranty. You will need to get a carb and intake etc. You can probably build one cheaper, if you shop around and do your home work. But if you figure your time going and sourcing a buildable core, let a lone heads decent to start with, and all your time cleaning and inspecting, that $1600 isn't a bad deal. Especially if you need machine work done. You could be driving your ride in no time. Just my .02 cents on it.

    Times 2. The 1600 is very reasonable and you get a 3 year warranty.

    It's a winner in my book.

    And yours and mine don't work for me. That is odd. Let's try this. 4th one down on that search.

    Appreciate your input but I'm enjoying the work and learning experience of working with the current engine. Everybody here has helped me a lot. The car runs good now, the motor is tight with no leaks and good compression, I'd just like to get a little more power from it. So I guess you'll just have to continue putting up with my uneducated questions and hope you don't get tired of answering them.

    Pardon me for taking so long to reply, sometimes things need to rattle around in my brain before I make a decision. So I need to ask, can a good set of heads be bought for around $1,000? If not, without going crazy, how much would a good set cost and where should I look?
