Re: Will this work for me?

OK, OK. I have a 1407 on a 355. They come from the factory slightly rich. I rejetted two sizes down on pri/sec and went too far, got surging and white plugs. rejetted to one size down and is perfect. You can read my signature for the other engine mods. I just installed a 4 hole 1" spacer and my burn out distance increased about 10 foot, I get right at 16 mpg at 80 mph, most of that is trans and rear ratio. I swore by Holley's, even when I was replacing the power valves, but over time I grew to hate them for daily driver use, the last one I still use for 22 pistol practice. It will take about ten minutes to change pri/sec, it all comes out the top, if you aren't drinkin coffee it may be shorter. You can get the jets from Jeg's/Summit for about 12 bucks for both and shipping. Go to Edelbrock website and you can download the complete manual for it including the jet chart. My 2 cents, steve
