Thanks very much for the info Force Fed! I'll call MSD to see which sensor I can use. When I get it all hooked up I'll shoot you a message with a couple more questions if you don't mind?
Thanks for the info! Ok, I've got a bunch of questions for you but I'll just start with a couple haha.
-A 1 bar MAP sensor should be good for me where I'm not running any boost correct?
-Do I put less timing advance in it when the vacuum is high? Like say cruising on the highway at 3000rmp?
It's time for a clutch upgrade in my 71! What do you guys recommend? I plan on running around 550HP after the winter so I need something that'll at least hold up to that! Thanks!
I did some more reading on the map sensor and I found one that'll plug right into the box and I can plum to a manifold port on the rear of the manifold. I'm not completely sure but I think it's only use is for timing control in boosted applications. I'll have to give the MSD tech line a call on...
Thanks for the input Force Fed. I did what you suggested with the ramp and then bumped it up to 36 total and kept the initial at 20 and what a difference! I saved another 4 degrees of advance on the box so I have that much adjustment without having to move the distributor when I get it on a dyno...
Does anyone know of a vented gas cap that will fit my 71RR? Possible even a part number? I've done a bunch of searching but I cant find anything that'll fit for sure. Here's a pic of my current non-vented cap...
yes it does have a plug for a map sensor but I'm not running one because I didn't know a way to jimmy rig one to the old dual plane manifold. The MSD tech said it's not mandatory to run one. Do you think I should? If so do you have any suggestions on one that I couod rig to my manifold? thanks!
Thanks for the input guys! Finally got it up and running yesterday morning and its hard to believe the difference in drivablity at low speeds and idle! I'm happy with this timing curve so far but she doesn't seem to have the same pull above 4000 so I'll bump the total timing up to 36 and try that.
