Hi am new to this site, and i am new to big blocks. i worked with several engines in the past but never paid attention to the big block. i am currently building a 454 for a 1987 monte. i would like to build something that will get me in the low 12 and still be streetable. the block numbers are 40069286 head is 14092360 and crank is 353039. is this a good candidate the block is a short deck 454 with 4 bolt main. the crank is cast standard. i am unsure of the heads they are open, oval peanut heads.

i would like to use the standard crank and rods. i plan on polishing and weight reduction and shot peening.
i plan on boring the block 30 over and putting studs for the mains. i would like a cr of 10.5 to 11.0 to 1 ratio with the heads i decide on. i want to run on 93 octane. what do you guys think. is this a good setup to begin
