Now that is odd.... That website lists the 427 S/C as 1965. The S/C was not available until 1966 (First one in Jan 1966 to be exact). The S/C were made to sell off the remaining 1965 Comp cars that did not sell.

It lists the standard 427 (non-S/C) as BJ/BK?

I wonder if the low rise and BJ-BK were used on the 428 blocks later on in the cobra production.


Yes, I did read that the Comps were single carb 427's and the dual 4bbl were in street cars, but I cannot find any history on this to confirm.

Then again, it is hard to confirm history when no two cobras are a like. maybe there is a cobra out there with MR heads, LR intake and BJ/BK carbs because that is what was available on the shelf at the time......Or specific to that buyer.

Also, I thought it was the manifold to head angle difference, not ports, between the MR/LR that made them noncompatable.

This is an interesting topic. Hopefully some of the other EXPERTS will chime in?
