Re: 1969 L78 396 375 HP Dyno Test
L78s MUST have headers to get everything out of them, IMO. Timing all in by 3k. I have this set up in my Nova and it just screams and has stayed VERY reliable for the past bunch of years, only deviation from stock are roller rockers, no ported heads, no larger valves, orig 569 flattie intake, orig Holley 4557, orig cam, orig compression, bored 30 over. do have a Pypes exhaust system with transverse muffler mounted in stock location. I think dyno'd at about 425 @ 5700, right about where it should be

Is there space for the back drive rod with the headers?
