I have the stock 350 2bbl in my Skylark, and have replaced the front suspension with all Global West parts, including the springs, which are correct for a 350. I would like to put my 455 in it, with the TA Aluminum heads. I was wondering if anyone knows the difference in weight between the stock 350, and a 455 with Aluminum heads. Would I still need to get big block springs?
Simple homemade test: Engine weight wlil probably be 100 pounds more. Have a friend apply weight to the front bumper, then watch how far the springs compress. That will be your new position. If your old springs are worn out anyway, might be a good time to replace them. If they are in pretty good condition, I wouldn't bother. -Bob Cunningham
weight transfer=weight x cg height / wheelbase x g lateral weight transfer= weight x cg height / wheel track x g If you want to get high tech bout it.
