welp after some saving up, scrounging around, and genourous donations i think ive fot everything to build my 454

heres what ive got.

454 marine block .30 over
12.5 to 1 speedpro pistons
comp roller cam. .714 lift
gm steel crank
gm 7/16 rods
team g intake
1050 holley domintor
1.7 comp cams aluminum roller rocker w/ comp lifters
gm iron ls7 heads. square port
msd 6al-2 ign w/ billet dist.

im guessing this will be a race gas/ 93 octane mix

so i guess im asking any and all opinions on this setup. advice?? how much power do you think ill have? feel free to say what you want it wont hurt my feelings

this motor will be going in my mudbog truck w/ tractor tires. it will be used for racing though a 200 mudpit
