I know its been a while since this post has been active but are these still available?

Original poster hasn't logged on in over 3yrs.

dang, well thanks anyway

CP Perfomance/Hardin have them listed on the web. These have not been made in years so they maybe the ony dealers that have them sitting for years. Even the 8.3 and 5.0 Whipples are becoming really hard to find. There is very little support for them even if you find them. I know because I have the 3.3's (being used on my boat) and had to have work done on them recently.

I know, just that im a sucker for nostalgia, they perform, and they look so cool. that and obviously im looking for a more cost effective upgrade to my current setup than purchasing brand new. I know servicing these older ones can get tricky but whipple seems to still have a lot of the parts still sitting around. Heck, they even found a 20yr old discharge plate for me recently lol.

I just picked up a quad rotor Carbureted setup, and I have a complete 2.3 marine setup with 15hrs on it, if anyone is looking for something to go on a 454 or smaller engine...way too small for a 509.
