Got my 69 firebird on the chassis dyno with the new 535 and tiger heads. This is more of a street car than race car as it has no roll bar, 3500 converter,3.50 gear,and the engine idles down pretty good. I feel the engine is a little weak because it only puts 553 HP and 491 LBS tq. to the ground. My question to ya'll is who has chassis dynoed their street/race car (with resultant 1/4 mi times)so I could have something to compare to? My goal is to be able to run a high 9 sec. 1/4 while looking and sounding stockish (on the outside). It has 3" exh with 4 mufflers to keep it quiet. The intake is a sheetmetal piece that I made and posted to be critiqued and based on the responses it may be my problem. I will post a dyno sheet later today. This car also weighs 3735 with me in it.
