Over the winter I built a 439 c.i. 18 degree sbc for my Vega. Well...really, I had a professional assemble it with the parts I provided. It dyno'd at 755 @ 7000 r.p.m. I was very pleased with those results, however my first quarter mile pass was disappointing....10.01 @ 142 mph in a 2600 lb. car. Heck....my 550 h.p. 421 went 9.70's! The motor was falling on it's face at full throttle immediately after leaving the line. Upon inspection, I found that the fuel regulater adjuster had come loose, and my fuel pressure was in the 4 lb. range. No problem...fixed it. Also....it ran extremely hot....like 220 - 230 on the return road. I know an engine will run hot, when running too lean on fuel, but I'm concerned even with the problem corrected, after running the engine for 15 minutes, and watching the temp. creep up to 195. I'm using an electric water pump, 3" radiator w/ fan, no thermostat. Any suggestions on how to get the water temp down without going to alcohol? For comparison....my last motor was a well built 421 c.i. sbc, 23 degree, and always ran around 170 -180. Never got any hotter. The c.r. on the new motor is 14.7:1.
