Here is the deal... I finished up my engine early last month and I am still piecing together my FI system to what I want. However, I want to get my engine broke in and ready to install. I don't want to spend a ton on a distributor (that will be getting yanked soon after) but I also want a good setup to run until the FI setup is ready to go. Give me some options gurus!

Can I run this with a Bosch blue i have sitting around?... http://www.amazon.com/Pertronix-D186604-Fl...r/dp/B004C02I1S

I'd rather not run vacuum if I don't have to... I just set up a test stand to fire this bad boy up... Oh and I'll be running a set of dual webbers with it ....

if you go the svda route. run a hose from each vacuum port on your webers (im assuming there IDF's) into a T then one hose from the T to the vacuum can in the distributor. then time to 28 degrees full advanced. with the hose off.

Oh wait before I go too far. Memory just kicked me from my time in engine classes... I am running a more aggressive cam, not too far out there just a mild cam... but i remember that with greater duration and overlap you lose vacuum... This is a mild 2056 I built so with the ignorance of the unknown should I stick to mech advance? Sorry to throw that wrench late in the conversation....

that could be the deal breaker......if the cam wont provide enuff vacuum signal then it wont pull the advance in.... sooooo, to play it safe, and not have to buy a bunch if distributors, you may be better off going with a mechanical advance dizzy. its only temporary anyways right? an 009 will work, just not optimally. if it was me, i would find a good "cheap" german 009.
