Mark's ADHD/ADD/DWD 3.0 /6 conversion thread, Woohoo! It runs awesome, but it's never done.... Options

[Mark Henry]

First I'm 52, so I'm not in danger of dying of old age any time soon (knock on wood), but if I don't get it in gear and get this done I'll be too old to enjoy it. My 914 has already been off the road since 2009 and that is just too long. Life has gotten in the way these past 4 years and deciding to homeschool my two kids with me going part time work (so low funds), full time teacher (so no time) didn't help.
But I have been picking away at jobs and collecting parts and I'm pretty well ready to make the push to get it done. Also my boy has decided to go back to regular school (starts next week) and the girl is super easy to teach by herself.

I'm also pushing to get my almost completed '67 VW bug project done as well.
The bug engine is where this started, I a quest for power I began building a type 4 2.6L engine for my 914, then I got sexed up by the /6 (IMG:style_emoticons/default/wub.gif)
I'll start a VW bug thread (later) to keep the 2 projects separate.

So what have I collected so far???

Well.... here's my build sheet...

First I pull the factory plugs and then the spray bars (tubes) come out fairly easy. Not shown is the rear line plug actually has a point on it and this is what holds the spray bar in place, not the plugs.
