Thanks for the replies , It is fun trying to decied how to have more fun
I did decide on having a engine built . With break in time , ballance card , all the suggestions that George A. (Guess ford) has on his web site . As far as posting this topic , A friend and I got our cars dynoed at the same time , 428 had about 100 lbs more tork . The tables are tilted . so with out sending 5 to 10 grand I was hopping for an easy fix . I could stroke the 390 , but most of the other parts should be upgraded to the top shelf . I mentioned the big block only because Im reusing all the other parts . Valve covers , collector pipes , intake , pullies ,etc.
I remember reading a post here at cc . Static compression vs. calculated compression (?) So if I want to just barely run pump gas what is the highest compression can I build . I have 10.5 to 1 now , does that mean it is less under load ? If I build 12 to 1 will octaine boster work ? OR will the engine turn to junk . Why does the 427 have more tork when the 428 has more stroke ? Thank in advance .
