I should have pics to post by tomorrow. It has right at 1,000 miles. Never a drop of ethanol blend fuel. And a bottle of Gibbs Carb Defender in every tank.
Box Stock jets and squirters - no modifications of any kind.
Summit sells these for $592.00.
I'd sell this for $400, shipped in its original Holley Box.
Feel free to PM or reply on this thread.
FWIW - I will be at the KC Arrowheads Pontiac Show on June 2 in Olathe KS - usually draws a good bunch of cars from KS, MO, NE, IA if anyone is interested and is planning on going to that show, I can hand it to you in person.
