does anyone know if the holley 250 powercharger supercharger will fit on to my 305 becuz its made for sbc. does anyone know. im not concered with hood clearence. so if anyone would know please let me know thanx.

Small blocks are small block as far as the intake from 1965 or whatever to 1986, the 87 up changed bolts a little bit, so it shouldnt be a problem.

alright so if i can get any size blower for a sbc that is like from whenever to 1986 i should be fine. thanx
