Hi,
I ve just finished my 250-2v swap.
I went for the first test ride today.
the engine in performing good at high RPM, but seems lazy to accelerate from idle.
what setting (meterin block, pump cam, squiter etc ...) would you recommend from my holley 350. I m curently runing on the orange cam in position 1. (Was on 2, i ve try in 1, no change)
I ve pulled plugs after a 40 min intown run. they seems a bit rich.
carb is new from holley and it is said to be a O-7448 primary jet 61 pump nozzle 0.031 power valve 85.
the engine is a 200 block with a 250-2v head, (little oversized exhaust valve) with DS2 ignition, a CI exhaust manifold and single 2" exhaust line. the car is an Auto with mustang stock 7 3/4 rear.
choke is not connected yet (by the way how did you guys dealt with it on 66 mustang (there no room there for it))
when moving form park to frive, rpm are droping, and engine eventually die sometime.
thanks for your suggestion.
regards
