[QUOTE="CleoMar, post: 635960, member: 25534"] I went with an upgrade on my existing 1600 dual port motor to a 1776cc. Fairly simple upgrade and gives me adequate power. Perhaps 85bhp. Added a drop sump which increase capacity to 4 liters coupled with an external oil filter. Added larger fan but am going back to the original cooling fan. Cooling is good. Using two Weber IDF 40's with 28 venturis. vacuum for braking servo is taken from both fuel input manifolds which needed to be adapted for the purpose. Again a fairly easy fix. Rebuilt the original 3 rib trans to a "freeway flyer" spec with higher 4th gearing to reduce revs on the highway. Uprated valve springs plus I added a heavy duty clutch which in retrospect is not necessary given my driving style. Kept the compression around 7.5. Very happy with the outcome. I wanted reliability and good engine life. Could not see the advantage of going extreme since engine life is likely compromised and after all we are still driving a "brick". [/QUOTE]
