two intakes = 1 and 4 barrel
heads = not really sure, is there a difference between 4 and 1 barrel for the heads?
bottom end = sounds like they are all the same
timing cover = heard 66 is one year only?

What else are different between 1 and 4 barrel? rods?

Please let me know. thanks ]]> feeds@yuku.com (87Duker) http://sohcsix.yuku.com/topic/2168 Wed, 28 Oct 2009 17:41:49 GMT http://sohcsix.yuku.com/topic/2166/t/removing-harmic-balancer.html feeds@yuku.com (DICKBURNS6fke) http://sohcsix.yuku.com/topic/2166 Mon, 26 Oct 2009 12:39:13 GMT http://sohcsix.yuku.com/topic/2161/t/new-with-ohc-looking-for-help.html feeds@yuku.com (87Duker) http://sohcsix.yuku.com/topic/2161 Fri, 23 Oct 2009 10:24:22 GMT http://sohcsix.yuku.com/topic/2154/t/Basic-OHC-maintenance.html Thanks,

What are the modifications that I need to do in order to convert in to a 4bbl? Do I need to reroute the metal fuel lines, change accelerator linkages?

How was this accomplished as all the info I have says that 230 1bbl heads all had the same volume - 59.6 cc-

From Woodland's guide:

I'm sure of the first three - checked engine blocks in the basement. Not sure of the last (230 4bbl).
Haven't seen this info anywhere and it's not discernable from the PMD manuals for 67 and 68 (which I have on hand)
