They pop up once in awhile and sell fast. 400ish was the going rate. I have one that is mostly NOS I'm thinking of selling.. the newspaper in the packing is from the 80s.
Mine is set up with Dominator base but Spectre makes some nice intakes for Qjets, reg Holleys. Not brand new but great shape. .15 and 2mph and but I found I could get most of that with just spraying water on intake between rounds but then you have water to deal with. The ticket would be to run this and spray or ice the intake. Potential for .2 and 3mph. That's alot of gain with no moving parts.....
If only i could make my mind up with what to do with that car.. it'll be 20 years I've owned it next month. I thought I'd clone it to a 70 apollo GSX at the 20 year anniversary, which is why i bought those parts from you. Maybe I'll do it at 25 years....
