MercCarb replacement

[biggerseagar]

I have a 2001 3000 scr with twin 5.0 liter with 2 barrel MercCarb's on them. Both carbs have been rebuilt and tweeked over the pasted 5 years and I still have problems with hesitation and just poor performance. I figure after 21 years they are in need of replacement . I am looking into replacing them with 2 barrel Rochester compatible carbs from a website called i-5automotive.com. They are $345.00 a piece compared to around $820.00 for mercury replacements.

My question is: has anyone done this to their 5.0 liter engines. The website says that the Rochesters are bolt on ready to roll. Are there any others places that offer a replacement for these MercCarbs?

Thanks

Roger
