So I have the opportunity to buy a downdraft redline weber two barrel, brand new and not a rebuilt for 150 bucks because some other customer flaked on the buy, so let me ask you this, is a redline weber better than the holley weber 5200 that replicates it? does it make better HP/better mileage? or are they just the same and I would be better off just buying tom langdons holley webber for 65$ Thanks in advance!!!
