1.82HP per cube!

You are the clown prince of clueless, run off of at least 2-3 forums.

When you can make 1.89HP per cubic inch with a legal Super Stock engine, that you built, let us know.

I have the iggy button pressed on him but everytime you quote him I can read it.
My feelings are that if a distributor ignition thats working perfectly is probably as powerful as a crank trigger setup. (If the fire is lit right it's as good as it gets) . A distributor is going to retard some due to chain stretch etc. This might be what the motor wants.
But with a crank trigger setup you can control exactly what happens and when it happens
That to me is a winning situation.

And I build my own engines, in superstock. But I only make 1.70 horses per inch...
Oh wait a minute thats at the wheels, through an automatic trans.
A 2600 pound car that can go 12.40's with an N/A 4 cylinder automatic.

CLUELESS comments doesn't close to describing this level of nonsense!

I notice your Stock / Super Stock "friends" don't seem to get on here and back you. What's up with that?

I use a crank trigger because it gives me a " warm fuzzy " feeling.
I do like its rock steady state though.

Thanks for the feedback guys. I understand what you guys are saying and agree. I just wanted to make sure I was thinking right. Right now I just have a locked out billet dist. but I am going to put on the crank trigger. I was just curious about if there is any actual horsepower gain or just stability in the timing. Thanks again!!!!!!!

I put one on the SS 396, and saw a considerable improvement in timing stability and some small improvement in performance, and we already had the best state of the art distributor based system MSD has.

Jamie, you made your decision about your car and your money, good for you. Me, I must be doing something wrong when a guy with a mid 11 second car is convinced based on the opinions he reads on an internet forum that the addition of a crank trigger will reward him with quicker and or faster MPH on the time slip due to "more stable, rocky steady" timing yet I've got about 4000 10 second time slips, 1000 9.0x time slips and numerous 8 second time slips from two BBC combos with billet distributors that every time I've set the timing it too is steady at RPM. Further, the clamp has never loosened, the timing has never changed due to oil viscosity and temp and never in over 2 decades have I had to constantly monitor a distributor for fear of component wear but wait, it gets more crazy...the MSD billet distributor in my 950HP BBC has ~ 18 degrees of mechanical advance in it. Yep, you read right, it is NOT locked out yet somehow, I'm able to make pass after pass after pass where my 60 foots and ETs typically vary thousanths(.00x) on any given day. Guess I'm just lucky or maybe all this talk about more stable timing means NOTHING on the time slip with engines like yours and mine.

Again, Jamie, your car, your money, your time, your decision.

Hey 1320, turn off your computer and turn on your TV! "Pinks" is on again.

Ed , are you quoting ME? I never said I put one on because I thought it'd run quicker.
I did imply there was some timing variation ,although insignificant...............I just put one on because , well , because..........LOL

I wasn't going to join this but I figured I would stick in my 2 cents. I had a problem with with my engine in the begining of my race season with a high speed miss above 6500. I chased the normal things, but wound up with a cam profile issue that caused destabilization in the valvetrain above the rpm stated above rpm. After a cam change my problem was solved. One of the conditions that was resolved was the timing jumping around while trying to set it. My issue is a small base circle cast cam core that was flexing with the aggressive lobe. The new cam had a different lobe and a slightly bigger base circle and cam core. I figure my cam was flexing and this was the reason for the timing variation.
I can see benifets to a crank trigger, when you are running very aggressive roller cams with alot of spring pressure causing cam flex in certain circumstances, and timing variation. With a crank trigger you eleminate a few parts that can cause an issue, nothing is more accurate than taking a signal off of the crankshaft. If you have a big enough cam core, and the right lobe design for what your trying to do, I'm sure a distributor will work well. I'm not really sure you will any ET in one over a good distributor. But I'm sure it won't slow you down. Your mileage may varry. Good luck.
