Idly thinking about having more POWER in the bus and wondered, hypothetically like, what the pros and cons of each of the above would be to achieve a goal of something like a 0-60 time of 9 or less seconds. Starting from a 1776 with standard cam and a single weber progressive and stock exhaust what is in the van now. Pulls well enough for now but never hurts planning the next move. My thoughts are that the 1776 would never meet the target so better off starting with a new build engine.... But what cc's would I need and should I go type 4 or even Subaru.
