Please help :
I have a 67 with a recently rebuilt 289 - near HiPo specs:
4 bbl Holley 650 Street Avenger carb
Ford HiPo highrise intake
Crane mechanical lifter cam
Decked and ported HiPo heads
Balanced and Blueprinted
Pertronix in the distributor and rev limiter unit
The story:
Car ran great until last summer, then battery boiled over - acid everywhere
#@&*!
so I cleaned out everything and car has been sitting for 9 months..
I replaced
>New Alternator with Chrome 60A unit
>Put on gold '67 HiPo look underdrive alternator pulley (and belts might be tigher now - too tight?)
>New starter solenoid
>New Flame-thrower epoxy coil
>New spark plug wires
>New optima battery
>New in-line gas filter
>Drained and refilled radiator
(also replaced cowl brace, montecarlo bar, and other non-engine items, etc.)
So today is the big start-up day with everything replaced...
Starter turns engine over strong
After several tries, it finally fires up ..seems to need heavier application of gas pedal
I run it for several minutes with my foot holding it between 1500 - 2000 rpms
Pump it up to 3000 rpms, sounds strong
...but as soon as my foot comes off, engine abrubtly dies - no idle at all
spray carb with choke cleaner, and retry - same result over and over
the engine used to idle smoothly, now it won't hold idle
Thoughts??? (help)
