Good Thread and an interesting twist to the Poll ?????
I have an original 1966 427 in my Unique......Square internal cylinder casting as opposed to the round. Built from scratch. Edelbrock heads, Arias pistons, Eagle rods all internals from Gessford, stroked to 454 cu.in. Great motor looks right and does all that I want it to do. But, no matter what you do it is a 37 years old block !!!!!
I saw fireman Mike's CSX Aluminum block last Saturday at breakfast and was totally impressed. BTW you can NOT!!!!! trust the block to start building directly from Shelby....Check the alignment in the cam and crank holes and bore accordingly. The entire block needs to gone over carefully before you start, the grade eight bolts in the mains need to be changed out for ARP pieces etc.etc.
Given the choice today I would go with the new All Aluminum block and in the fullness of time I probably will
