    I'm in the process of bringing a dead horse back from the grave. In this case it's a 91 S-Blazer with a busted crank. I'm about to pull a running 4.3 from another Blazer and do a transplant. While it's on the stand I'll be doing front and rear seals and checking the timing chain. I'm getting a very real craving to try for a little more low end from that 4.3, as it will be towing a lot of the time and getting saddled with a plow this winter. I've run Edelbrock Performer cams in big blocks before, and the Performer manifold on a small block, they seem to work as claimed in those applications. Now I want to put the set on the 4.3, cam and manifold together. Has anybody used them? If so, are they worth the money?

    It is hard to get much more torque at the very bottom of the rpm range without some type of artificial aspiration like a supercharger. There won't be a noticable difference till 2,000 to 2,500 rpms with those parts. You will also definitly want to keep the fuel injection for maximum torque.

    I'm keeping the fuel system stock, rather than mess with the computer at all. Now, back to my original question, does anybody here have any experience with the Edelbrock cam/manifold combination in real use?
