Show us what you got! and when are you gunna get that beast out?

He is a very close friend of mine, still a bit shy to introduce himself so let me do it for him.
His name is Darrin, been an US muscle car enthusiast since i have known him (about 20 years) owned several tough machines most of them blown V8's. His current ride is a semi restored 67 Pontiac GTO with the toughest V8 GM built so far, 572 big block Chev.
620 horsepower was not enough for him so after a few JD's we bolted on a brand new 671 blower originally twin 850 HP holleys that made 960 hp on the dyno. The holleys were traded recently for an Enderlie Bird Catcher injection hat modified to accept electronic injectors and custom fuel system running Motec ECU.
It is getting final tune on the 5th this month just in time for Summernats. Entrant number, guess what......572 of course.
Keep an eye out for it.... He can not wait to drive it and he does not baby it either.
Cheers on behalf of my good buddy  

Chris.

Does the blower make it hard to adjust the points??

Sounds like a certain light blue royal bobcat car ! It is a good looking thing !

Only Pontiac engines run points dizzy's these days  

That's probably because for the most part, points work just as well as the 'bug zapper' ignitions.  

I've only gone to electronic ignition because the cost has come down so much, it's now cheaper than having points, on a daily driver.  

Bearing in mind that I changed the points at every 5000 mile service, which for me was at least 3 times a year - for 6 of the (nearly) 8 years I've had this car.

With a electronic ignition, my car doesn't go any better or start any easier than it did when I had points in it.

It starts on the first touch of the key, with either points or electronics.

Don't get me wrong. Of course there's a place for high output ignitions, but the number of times I've seen a big MSD box on a standard 327, 308, 302, etc.  

At the end of the day, a spark's a spark.  

O.K. Do not get ME wrong but these days it is the SIZE of the spark that matters.....:boxing:

On a 'stocker', what difference does it make?  Like I said, my car doesn't run any different with electronic ignition than it did with points.

I'm going to have a look for an article I have lying around somewhere.

They had an engine on a dyno.  Can't remember what type, probably a SBC.  They put 3 different ignitions on it.  A new points dizzy, a new HEI and a big dollar aftermarket unit (can't remember what brand).  Also, (obvious when you think about it) they used new leads and plugs with each ignition.

The engine was a stock rebuild.

The difference between the points dizzy and the top $$ bug zapper was only 5 horsepower, with the HEI in between.

Again, I'm only talking about a stock or close to stock engines, like those 327's, 308's, 302's and my 215,000 mile 455.

Why waste your money on a MSD box or the like for something like that?
