the increased flow the Edelbrocks provide may or may not matter if your cam is not able to take advantage of it. Does your car currently have a lot of low end torque or is better above 2500 rpm?
I have to agree with your cam questions completely.. I think before going through heads and all that maybe just a simpleI Cam and lifters change could make the whole entire difference..
To the Op remember your cam is the conductor.. Pistons go up and down and heads breath, but the cam tells it went to do it how to do it how much and how much not too.. for a noticeable bump in performance or not LOL.. I would consider a cam and lifters and possible spring change that would be a lot cheaper and possibly more bang for your buck. You could at the very least when you have your cam out take your micrometer and measure the high to the low and measure the base Circle and subtract the difference and that is your lift.. it's very hard to figure out duration but maybe learning some more about that first would be a good Avenue.. at the very least you would know exactly where you stand with your cam and to me personally I believe that's extremely important does again that's telling everything else what to do and when to do it..
