Got the gaskets cut tonite for the oil holes and i installed the intake. Also I phased the rotor and indexed the cam sync sensor. Its offically a motor now!!! Just gotta pollish up my covers and install.....index the crank sensor and put on the vac pump/headers/alternator and water pump and i got a running motor!!!! More tomorrow.....

Pic of the headers all wrapped up with the DEI Titanium Heat Wrap...


Pic of the intake bolted up to the motor after i cut the gaskets with snips and folded over the pieces to allow the oil to drain out of the heads properly....


So here i used a degree wheel and a piston stop to find TDC. I put the piston stop in the #1 plug hole and turned the motor forward till it stopped I had 72* then i turned the motor all the way backwards till it stopped and i had 46*....this gives me a difference of 26* between the two you split that in half and you have 13* now add that to the 46* and you get 59*. So I pull the stop out and turn the motor to 59* and thats my TDC #1 compression stroke.



Next i phased the rotor.....turn the motor to your timing at peak torque which is about 34* in this case.....so i backed the motor up 34* which brought me to 93* on the wheel. Here i lined up the rotor with #1 on the dizzy cap and marked the position of the dizzy where it fit the best....


next i had to line up the cam sync sensor in the dizzy........its simply a magnetic pickup sensor that needs to be triggered once a revolution of the cam 10-80* before the crank sensor signal.......so in my case:

my max timing i will ever run is 40* +10* for processing time for the xfi gives me a crank trigger setting of 50*btdc....so +10-80* = 60-130* BTDC i need my cam sync sensor to be triggered.....so
with the dizzy installed and the rotor phased i turned the motor to 60*btdc then continued to turn it backwards untill one of the triggers passed the pickup in the dizzy and i stopped there......it wound up being 116*BTDC....perfect!!!
you can see here what the mag pickup looks like in the dizzy....


next i marked the trigger i was using and i now need to cut off the other 7 cause i only want this one pulse every revolution to tell the xfi when the firing order is starting.....



more tonite.....

Can you give me more details on your ignition setup. I am doing a build with almost every part you are using. I will also have the Victor EFI intake and I am looking for a solution to the opti. I have considered LTCC and EFI Connection setup's but have never seen a setup like this. I am very intrigued by this and I need more info PLEASE. Thanks Michael

Basically with these aftermarket ECM systems the computer needs to know where the cam and crank are to do its job. I use a dual sync distributor which is a basic small cap distributor but under the cap there are magnets and triggers that rotate. Since the distributor runs off the cam these triggers can reliably tell the ECM where everything is. Tried to make that as simple as possible.

I don't know what distributor the op is using I do believe xfi has a dual sync distributor now. Fast xfi is an excellent system an I would have gone that route if I knew by today the support would have far surpassed dfi.

To the op.. Are you building your own dual sync ?

The eficon reflectors are 24 or 58 etc and I believe my dfi needed something like 4/1 . I am considering buying their cover, taking their reluctors to a machine shop and have them shave off teeth until I have 4/1 inputs for my ECM. This way I can run a generic small cap or even a large and not have to shell $500 for a dizzy and always be wondering about accuracy (wear on drive gears). Btw are you using a bronze gear or steel?

My AI SR package with a stroked 401 bottom end refresh will be done next week. No where near your HP/TQ numbers with the single plan, vacuum pump, and engineering you've put into this combo. What CR are you projecting with this current build? I've also been told to move up to 1 7/8 LT headers. Unfortunately, nothing like that exists off the shelf for b-bodies. Will have to go custom.

Tremendous attention to detail.
