 Posted: Tue Aug 05, 2003 10:53 pm Post subject: 350 HOLLEY |
 |
|
i saw the inspiration on hallets engine. and i was wondering if a 350 holley goes any good on a fully worked top and bottom 2 litre. in comparison, does it give any more power rather than flooding it campared to a 40ml D/D?
thanks guys |

mmmmmmmmmmmmmmm
i was going to buy a brand new one for my G180 after it got rebuilt because they are simple and everyone has a fair idea how to tune them BUT! my engine builder told me that they are only really good as a "flat out carby" and thats putting one on my worked G180 would give me pretty shitty throttle responce due to both the butterflys opening at the same time. I still have a 2L weber on mine just while I am running the engine in but i'll probley put a weber off the 250X flow ford motor on it because they are bigger and they have a mechanical secondays. Let me know how u go with the 350 if you end up putting it on because i am interested |

| It all depends on how its built. As long as you choose the correct power valve, main metering jets, accelerator pump nozzle and booster venturi type and size theres no reason why a 350 holley shouldnt work wonders. need help? write back |

Just remember that 350 is only the airflow rating, all of the fuel deliveries and velocity of the air are variable.
Anyone who needs help with jet sizings, powervalve settings, boosters and pump shooters send queries my way.
