Lewis Maudlin Posted March 5, 2002 Share Posted March 5, 2002 OK, I have a 390hp 355sbc with the Edelbrock Performer RPM set up. I had a Holley 600 but I didn't like the gas smell all the time. I switched to a Carter 625 which doesn't smell as bad but is old and doesn't have the WOT punch that the Holley had. Also, it doesn't fit under my hood as well as the Holley. I am thinking about either one of Barry Grant's 625 Road Demons or a 670 Street Avenger. Do the Road Demons have the power valves that blow out? The price is relatively the same. Does anyone know which works better and needs the least attention? Any suggestions? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 6, 2002 Share Posted March 6, 2002 I would go with the Road Demon. I'm pretty sure the power valve issue is addressed in both, but the Demon is made of better materials (billet baseplate vs cast) and the workmanship appears to be better. I used to work for a large mail order speed shop, and we sold both, but most customers seemed to prefer the Demon series. Quote Link to comment Share on other sites More sharing options...
