Quickest ever with my Valiant

Very nice. What has been done to the heads? My 360 in a 65 Valiant has been a disappointment this year. It only runs 9.60s @ 76 mph in the 1/8th. My 60’ times are around 2.3
Head is milled .125, oversized valves, and pocked porting in the bowl.
Bet your car needs either/or lower rear gear, higher stall converter
