Woo-hooo! 1st run on the motor
Biiiiig day today. The story of the day was getting the little details buttoned up on the car. I had to finish hooking up the radiator, fan, and trany cooling lines. Re-connect the shifter, tighten down the body mounts (I just got the body back on last Thursday and hadn't tightened them all down yet), and connect the steering wheel back up to the steering box. Then I dropped the battery in the car, took a deep breath and turned the key. Nothing. I had been fighting the wiring to my starter earlier in the week as my original tags had all faded. In the process I had a large gauge red wire that I thought was a ground wire. I was wrong. It ended up being the positive back into the rest of the car. The give away was that the cig lighter had no power.
So, I took the wire and connected it to the +12 terminal on the starter. Then turned the key and this time lights! Click it to start and I barely get a turn over on the starter. Nuts! My battery went bad in the 6 months sitting there. It's a 3 year old battery and the guy I bought the car from before had it mostly just sitting in his garage before that and thus, the battery being bad is no surprise.
Off to Wal-mart to replace the battery. I get back, drop in the new batt, throw a little gas down the throat of the carb (fuel lines are brand new, new fuel pump, and filter) to help get it started. Turned the key again and now a solid turn from the starter. It coughs a little and then starts turning over but then stops. Of course by that time, the wife and duaghter run down stairs to complain that I'm going to have the neighbors all mad at me. I don't have the exhaust hooked up yet and so it's just open headers.....unbelievably loud but, music to my ears. THe wife protests about 5 times and then gives in. She knows that she's not going to convince me to not turn this over tonight after nearly 5 months of working on it!
I throw a little more gas into the throat of the carb and try again. This time it starts and when I give it some throttle, it comes to life! I bring it up to 2200 rpm to break in the cam and motor. After running a couple of minutes I notice that it's getting a little back fire when it drops near 2000 rpm. I run it around the range of 2000-2500 rpm and find that it runs very smoothly at 2500 rpm but it's a little rough below 2200. The oil pressure is solid and watching the temp gauge it starts climbing up to about 210, stays there for a while and then starts moving past and up to the yellow line. Its' then that I shut her down after about 8-10 minutes of run time. I don't want to overheat the motor the first run! In the process of shutting it down, I pull off the throttle and as it drops it's really sputtering and then drops out and burps some gas back out the carb. It's then that I notice that there's steam coming out of the outlet from the radiator that would go to the puke tank. I hadn't hooked up the puke tank yet. The rad had puked a good bit of water all over the floor in those last few seconds.
Not a bad run but I need better....of course!
1) Should my rad be spewing out like that? I had put in 1 gallon of antifreeze, do I need more? Hook up the pouke tank? Or something else?
2) The roughness and back-firing, I had not touched my Q-jet in putting it on the new motor. The motor is now completely without EGR. How much could that effect the operation below 2200 rpm? What is the likely cause of the roughness below 2200 rpm but smooth at 2500 rpm? IN setting the initial timing I had followed Vizards instructions in his book on re-building small blocks.
I'm going to give it more time in the morning when my neighbors can't complain about waking them up at least!
