Hello,

Many members of the Brickboard community have kindly helped me in regards to SUs and Webers. My personal opinion and the general consensus is that a pair of properly rebuilt SU HS6 or HIF6 carbs are far superior to Webers in virtually all respects, especially if you plan on making performance modifications to your engine. Additionally, SU carbs have a vintage look and were original equipment on various years of the 140 series. Simple adjustments and perhaps a needle change (very simple) make for a quick install to your vehicle. The downside is cost. You really want to purchase a very good quality set of SUs for your vehicle. That means purchasing a used set in excellent condition, or preferably, buying a refurbished set. Rebuild kits are expensive, and if you get a "from a running vehicle" set from Ebay, you might very well get something so worn you can't possibly adjust it correctly. I did that twice :(

That said, right now I've got a Weber DGV 32\36. Why? Cost. For the price of a complete rebuild kit for the SU, I can get a very good condition Weber with manifold, air filter, and needles. Weber DGVs are perfectly acceptable in a stock engine if you can live with average performance and don't mind swapping several jets in an effort to get it "just right". Webers also require a separate header or exhaust manifold.

In conclusion, Weber DGVs are okay, SU HS models are better. DCOEs are high performance (racing) carbs.

Good luck!
