I know that everyone always strives for big big big, but if you had a moderately built 350 or stock to mild 454 which would be better in a K5 ? How much more weight is a BigBlock? Plus 350's are so easy to find parts for and less expensive I believe. I have never had a 454, but dreaming again on a project. 350 or 454 ? <font color=red>BigBurb <font color=purple>IF YOU'RE SCARED, SAY YOU'RE SCARED !!
