am running red 253 with 600cfm vac sec holley in vh commodore. I am seeking an idea on the ideal jet size for this combo. I realise 600cfm may be larger than neccessary for this engine and am looking for suggestions.
Or should I go smaller carbie for better bottom end torque??

Insaen,
I run a 350 Holley on my 253/M20 combo. It's heaps big enough. If u can get a quaddie/rochester instead that may be better. If the donk was a 308 the 600 Holley may be better suited. Unless u seriously fang the car, it wont have the air flow to
