hot heders
:twisted: I've got a new motor: Dart 406,blower pistons,Edelbrock Victor Junior 70cc heads,Comp hydraulic cam,507/525 lift and 284/305 duration. BDS 671 blower 5% underdrive with BG 650 blower carbs. Hooker super comp coated headers. Fuel system is all new with high $$ pump and -10 line to the regulator,-8 lines to the carbs.
On initial fire up it had the headers glowing in about a minute while breaking the cam in. I changed the jets to 76/80 and installed a pyrometer. On the next try, about a minute after cranking the temp was 900 at idle and about a minute later the exhaust temp was 1150 at fast idle. Checked the headers and they were glowing again. Any thoughts??
Thanks, Pat Posey
