I agree holley are great..... For chevy's! 8 years ago on my 77 trailduster I pulled that thermoquad and replaced it with a holley 750 double pumper and then a vac sec. they have their problems but then putting back on my thermoquad one year for smog I started tinkering with it and bought a book and have never looked back (to see those chevy's with holleys in the rear view)the bad thing about thermoquads is the rest of the world that being part such as jets & etc. dynotune are you on ebay as dynotune1? man everything I watch and want this guy buys! (he has a fatter wallet I guess) I love this site can't believe I only just found it.
