428 Standard vs. PI
I am starting the process of building a 428 and want to know how big a difference there is in the standard 428 vs. the 428 PI. I already have a standard 428 and am looking for a PI block (hard to find standard bore) becuase I want to stay as close as possible to the orginal spec of the "street" Cobra.
From my reading I know that the main bearing webs are reinforced but other then that I can't find any block differnce. The PI seems to be the precurser to the CJ engines. Am I carzy building the standard 428. BTW, I will never race this car, it will striclty be street driving and maybe I might bring it to Lime Rock to open it up once or twice. All opinions are welcome. TIA |
fzabski,
If im not mistaken(and I could be) the 428 PI is distinctive for its solid lifters and the use of early 427 heads the CJ and SCJ had the stronger block . Whether its strong enough would probably have more to do with the quality of your build parts and balance of your rotating assy. |
nope ,did some quick research ,and you are correct, the PI and the CJ Both had the bigger main support,caps, and reinforcing webs.
The prices ive seen for CJ blocks ($4500 or so )would tend to get me to move up to a 427, or save $4to $6k and build your 428 .Thats plenty of Motor for the street. Good luck Karl |
