has anyone built one ? 420 to 454 c.i. small block. i am thinking about it for my new engine, and it needs to be able to handle a large shot of nitrous. i plan on touching into the 9s in street trim. i was only in high 10s this year at 130 , and my friend just ran 10.08 in his 86 with a 406 and 200 shot, so he will be in the 9s next year . also we live at 4800' eleavation

yes

 

for the money invlved your gonna spend i'd go with a big block if its a drag car and not gonna see much street ...build a 481 or a 511 flat top with merlin oval ports and a shot of gas (nos 200-250) should get you there

 

For what its gonna cost, just build a 454" big block. Cheaper, faster, and looks hairier.

For the record, Ive heard of small blocks over 480".

 

if i had a big block available i would go that way . i have always run BBC's in the past . this is my first try at small blocks. as you can see from my sig i got a decent set up (i think) just need a new short block and trying to figure out what to use to get to where i want.
thanks for your opions

yes i agree after lookin at sig lots of good stuff to lay around .........i would buy a dart little m block and a scat 4340 forged steel crank and with the other parts you got , i would also get some j&e pistons and build a 434

 

i did'nt build it but had it built by shafiroff racing engines in long island. 434ci, motown block,callies crank,lunati rods,dart intake,demon 1090 carb, dyno'ed at 654 hp 601 lbs torque to the flywheel just finished the install and hitting the track next week to se how it runs

 

THOSE MOTORS WILL ROCK.........GOOD LUCK

 

I agree, those motors are gonna rock you guy's worlds upside-down
