454 will hog up all my room for a/c and goodies. Also, with a camaro clip I will probably mash it into the street (have to upgrade all my suspension just to hold the weight). How would I deal with the [censored] end of my truck? The tires will get expensive having to replace em every 100 miles too. Small block seems to be the answer- unless there is something I don't get.....enlighten a beginner.......need all the help i can get.
