Here's my problem. I have a Merlin II Tall Deck Block with 4 Bolt non-splayed caps. I want to build a 547 or 555 with a blower Probably 14:71 (low Boost) lookin for over 1000 Ponies. I have a LA Enterprise Crank, Carrillo Rods.
Now do I spend the money and have the block converted to splayed caps or just run the 4-Bolt straight caps. I have read on some posts that converting 4-bolt main caps to splayed leaves less strength do to bolt hole material gone from original holes? Block is at machine shop in Vegas now. I have not decided yet what to do.
Info greatly appreciated...John
