Trickflow 240 or 270's on B block

still working on it......been concentrating on vehicle side ....frame ties currently then american autowire conversion....but i did attend a mopar weekend at norwalk and seen a b block in a 69 dart with a 383 victor with a 1 inch spacer... top of air cleaner looks like it would of definately fit if spacer was not there.....i also like TF flow intake rpm range compared to victor tf >3000-7000 rpm vic> 3500-7500 rpm
