I heard on the radio (my stock '72 Delco AM) that GM was sending a flex-fuel Tahoe to Colorado in support of the E-85 initiative and I wondered if there were any individual incentives for making a conversion. Lo and behold, there is. From what I can tell, you can get $2,000 federal tax credit in addition to what your state will give. I mean damn, wouldn't it be cool to drop a new 5.3L Vortec in a '72 Blazer that runs on either regular fuel or E-85 and get a $2k - 3K back on taxes? Am I confused or what? See www.ccities.doe.gov or www.afvmarket.com/incentives.cfm I drive my '72 w/ 350 A/T 90 miles a day and I'm getting 9-10 mpg. I'd love to drop a Vortec fuelie in there.
