73' 340/904 duster racestoration
So as i said last week i was gonna take this car to the track to get a baseline and now i know that i have my work cut out for me.
First off is that i bought a tachometer for the car, but unfortunately didnt have time to install it before going to the track. I went for a small inexpensive sunpro tach. I've never been big on the monster tach style tachometers. Hopefully i'll have a chance to install it and take pictures tomorrow.
Onto my day at the race track. After a few headaches surrounding my battery tie downs i was on my way. Which brings me to my next issue, mpg. I calculated that my duster was getting about 9-10mpg. No bueno for the times it ran. I'm thinking i need to look into either a manual 5/6spd conversion or an OD tranny conversion And EFI of some sort.
My first 4 passes were the same. 16.9 at 86mph, then on my last run it managed a 16.7 at 86mph.(got off the line slightly better) Each pass i had to leave off of idle/low rpms and it would still burnout through most of 1st gear. I expected this since my tires are 225/x/R14
I have one picture that i'll put up sometime tomorrow.
Lastly is more of a question to people reading this. Tomorrow i'm gonna check my compression and see if the engine is holding acceptable compression. If it is, im wondering what would be a good budget upgrade for my mid/late 70s 360? I was thinking of trying to find some magnum heads at a u-pull-it, get a nice intake manifold and a cam. At the very least i'd like to see if i could get this engine to make enough power so the car turns 13s(assuming its in good shape)
