    best racing ign system.

    This is the sort of thing that would require a bit of fabrication (or a similar aftermarket crank trigger with a 60-2 or 36-1 pattern) and some sort of aftermarket control unit - MicroSquirt if you're on a budget, maybe something like a Haltec VEC if you have a larger budget, want more I/O, and...

    best racing ign system.

    So - does the rule book mandate that the ignition appear stock for your engine, or that it just appear to be stock for something? If they have worded the rulebook badly enough, a set of eight totally stock LS1 coils (unfortunately, Gen III Hemi or Pentastar V6 probably aren't going to be as easy...

    turbo 360

    Not a bad plan. Turbo motors don't have to rev so they aren't as tough on the crank as an equally powerful naturally aspirated motor. Don't forget a suitably powerful ignition in your combo, and spending the time to get it dialed in right. Makes a world of difference in a turbo motor. Also...

    any one useing msd box with a vacuum advance

    I suspect it would improve things a good bit. Taking the time to really get the ignition curve dialed in can make for huge gains in mileage. As Ramcharger mentioned, however, you're always going to have a little bit of vacuum with a blower manifold since the boost retard and blower are getting...

    Big smallblock power..Turbo?

    The Bell and MacInness books are slightly different territory. The MacInness book is a very out of date book, many of the turbos mentioned in it are no longer in production, but it has very solid math and a very interesting look into old school turbo tricks for someone who wants to set up a...

    Big smallblock power..Turbo?

    The one gap with Maximum Boost is that the carb chapter is quite limited. The most detailed chapter I've seen on turbos with carbs is Hugh MacInness's Turbochargers.

    Big smallblock power..Turbo?

    Yes, I'm there - I post as Matt Cramer. From what I've heard, most of the blow through setups tend to run a bit rich at part throttle. You can get an engine to run at a very wide range of air/fuel ratios. Getting a blow through carb to work is doable, getting it to control the fuel as well as...

    Big smallblock power..Turbo?

    I've seen carbs used with turbos too. Tried it on my Dart, but the used carb I started with had issues. I've found EFI fuel mapping to be a bit easier than getting the correct air/fuel ratio out of a carb under both boost and cruise. With EFI you can change the mapping on a running engine at...

    The Truth about 318s

    Many of the "book numbers" appear to have been put where they are to help racers. The numbers can let you do a good deal of mods in the name of blueprinting, while race officials would have to conclude the mods done are still acceptable within stock categories.
