I dont know what you are putting this in but I have the same cam in my 98 k-2500 with the injection and it is a beast compared to the stock cam. It runs weel but gets about 8-10 mpg on a good day. I'd stick with fuel injection unless it is going is some type of classic car. I had fuel injection specialties in san antonio take care of the computer tuning for me.

I put it in my boat and am trying to come up with hp number to select a prop I origionally had it in a truck with the factory injection and headers and it seemed strong in there also had a surge when idleing and seemed a little soft on the bottem end but came to life around 3000 if you have the 4l80 trans the converter out of a 6.0 l will add some stall and help with the low end

i have a 454 vortec 96, i have a world production intake and it wont fit percfectly, did you modify anything on your intake ? I wrote to World production, and they dont have any intake for vortec.

Any old short deck big block carb intake will bolt right up to a vortec 454. Your heads and or block may have been milled down, that will cause problems.
