That makes sense. A hydraulic cam with low 500's " lift will generally have a duration in the lower 200's degrees @ .050. I did say generally. There are lots of variations.
But your 390 is running the way a nicely built street 390 should run. I'll bet you have headers too, right?
There's the biggest problem with a 390GT in the Muscle Car Drags that Royce shared the rules with us. To have a 390GT in a '66 - '68 vehicle be competitive seems to require headers or at the very least, Cobra Jet exhaust manifolds.
Is anyone running a reasonably stock 390GT with factory "GT" exhaust manifolds in the 13's & low 100's? Would it meet the stringent rules of that Royce posted?
My best to e smith in finding his problem(s) with his 390. Please post here to let us know what you find and the results of your changes/corrections. |
