A good number of people believe that the CJ blocks were made of a higher nodularity iron material, including the caps.
This would suggest that 'standard' FE caps are less desirable, though whether it's true or not, or how much, is anybody's guess.
Since you would have to align bore the engine anyway if fitted with different caps, why not consider going right to cross-bolt main caps?
Along with high quality main studs, the improvement in bottom end strength (far less prone to cracking up through the main-cam saddles) is very significant.
Used ones from a 427 block come up often enough on eBay (typically about $150-200), or they can be sourced through some of the known FE parts vendors.
There are also heavier-duty steel ones, designed to be easier to fit/install on standard FE blocks, such as the ProForm ones. As suggested in another post, a GOOD machinist won't have any trouble fitting either of them to your block.
With good CJ blocks getting harder and harder to come by, this investment should then guarantee that yours will be up for whatever you're going to ask of it, for many, many years to come. |
