Would like some imput
When I had a 318 in my 67 Barracuda at Bandimere it ran 16.5 with slightly warmed up cam, cheap-O headers, 600 Holley carb, all the rest was a stock rebuild
904 trans, 8 ¾ rear with 3.23 gears (one tire fire).
Changed cam to a MP 284/484 Hydraulic cam, ported 360 J heads, and RPM intake
.she when 15.7 with poor 60 times.
Changed to fresh 360 with Eddy heads, and MP 292/509 cam, 750 Holley
same everything else
14.5. Then added 4.11 gears and she went 13.8 @ 103 mph on the motor and 11.1 @ 122 mph on a 180 shot of spray. My best a Bandimere with the motor was 13.1 @ 105 with some good air
.a better converter would have been REALLY helpful with all of these combos. They all had the same crappy TCI street fighter converter.
I hope that helps.
