    Cool 750 dp holly vs 600 edlebrock

     



    I have a 68 elky with a th350 w/shift kit, and a 327 topped with power pack heads edle performer intake and a mechanic saying that the car is cammed but i have no idea if it is ...i am new to the muscle scene so any input on my quest for more power would be helpful. I picked the car up for 2,000 and plan on putting 5000 just into the motor and rear end ...i currently purchased a 750 dp for it and i am starting to wonder if it might be to much? Please feel free to give me any advice on what direction i should take and in which order.thanks

    I'll agree, you'd be better served with a smaller cfm carb and with that automatic trans - it'll be better with vacuum secondaries. Keep the 750 for track day at the strip..

    The 600 eddy will give you way more throttle response and better mileage. That 750 is more suited for a 500+ HP motor, especialy being a DP.

    well i installed the carb yesterday and WOW what a difference it made!! i am able to burn rubber all the way into the third shift ..at 25 i punch it and it just rips like no tomorrow....unless i think that's normal for a stock 327?? but if it is wow i could imagine what 500 horse would feel like...what would be the easiest way to check to see if it has a cam and what direction do i head from here? that eddy did not even come close to what this car is doing now.
    thanks all for the response y'all gave me any other options on ways to figure out what exactly i have under the hood would be nice thanks

    Well.. I can guarantee that there is a cam in there! Now just what cam you have is a bit harder.
    Are you prepared to possibly have to pull the front of the engine down? How bad do you want the information?


    OH, and welcome to the site!

    I'm guessing its not easy to check huh....well I'm talking with a shop right now and they are suggesting to get rid of those heads and install vortec heads? With a mild cam ...so many people have different combos but I'm looking for something dependable and powerful ...I like how it runs now but don't know how dependable it would be so yes I will be taking it apart soon ..I have 5000 for motor and rearend etc....so how hard would it be to be in the low 12's- high 11's?? But streetable nice running cruiser if such a thing lol...thanks for the. Welcoming

    Too much. I just went through the same thing with my 350 motor. It came with a DP 750 Holley, and it kept flooding out, and hard to start after it was
    warm. I put a 600 cfm Edelbrock on my Edelbrock SP manifold, and it runs
    like a watch - perfect. I'm glad I downgraded the carb

    You asked about dependability and that is really just a measurement of time. It sounds like you just picked up this car so maybe you should give it some time and see what you like / dislike about it. As far as low 12's etc.. have you had it on the track yet? If so, what did it run?

    @ 34-40......I'll have it on track this Friday evening ..and I guess you are correct about giving it time since I've not had it long.so I will run it this weekend and repost on here what it did .
    @ Simi mike this car ain't having any issues as of yet it turns out the car seems to benefit from the upgrade so the question is what's in it? How fast is it on the track? And what should be the next step to rebuilding it to reach my goal IF it ain't doing what I hope it will do.
    I see your close to Bakersfield they have test n tune this Friday so I will be there .

    Fast on the track and streetable.....that's the dream of every rodder in the world! It all depends on your definition of "streetable"! Seen some absolute beasts driving up the street, even a Hemi flopper with the driver in a full fire suit that pulled in to a choke and puke one time.
