Only new Holley 4 barrel for around $300 will be a really generic vacuum secondary 600-680 cfm 4160 Avenger series carb with very limited adjustments. But I think thats what he wants,. ??

I paid $369 for a new Holley 600 cfm 4150 double pumper, mechanical secondaries. Had all of 50 passes at the track,.. I took a bath trying to sell it. IIRC I got $200 for it. 750 Holley 4150 will be $425+ for a new one.

$200 for a new Holley carb? 2 barrel maybe.

I personally cant stand Edelbrock/Carter carbs.
