Report - Edelbrock Thunder AVS

[Dirty Harry]

I bolted an Edelbrock 600 on my small block and adusted it once and have not touched it in 18 years. Great on cold starts and not bad on hot starting. Easy to buy, no maintenance, and no leaks. Money well spent, I'd say. IF the Holley makes 10 more horses, I'd be surprised.

cdnus .... I think what a lot of people miss here ( me included ) is that ProSystems builds a race carburetor . I may work ok on the street , but is really intended for the race track . If you look at the build sheet where the mods are listed , it seems to me that they are heavily weighted towards competition ... and that`s ok , as Pro says they build race carbs . I was just hoping it would have worked better in my application .

I believe the wording on their sight has been changed & some models eliminated.
When I ordered my first carb they were offering non-race carbs with hi-performance. I had very specific discussions about the application for my use with Patrick. Mainly street use, mileage important as I do many long day trips, in fact he did some mods to increase mileage that totally did not work & I had to reverse.
Good luck with your second carb, I hope it works well for you, as I am sure my case is unusual. I have a permanently installed O2 meter, so I am constantly aware of the performance of the carb. After many changes to my second carb it is now very good.

Just checked their site & according to information below they still build street carbs..

"We specialize in designs for programs starting at 400 h.p. (thats a great power level for any respectable street machine) and we have built carburetors as large as 2600 cfm in flow.

By specializing in only race and high performance street designs we not only helped ourselves grow into a strong, innovative and self reliant company, it also helped our customers by giving them a company that really knows and understands their needs and how to get results from their programs. "
