Ok this one may be a bit over the top, But I have been reading and well can't figure this one out...
I have a 60 FI the original cam, the injection is off her and is the original distro, the distro is from a 62 and has no vacumm advance she is a dual point setup...
Some simple (maybe not questions)
I read initial timing is 18 on the FI motor? But is that with the original distro? is so then what should I shoot for a total timing? And if so at what RPM should I set it at and what degrees? say something like 32?
And the second major question what points should I use in the distro, and what gap and dwell settings if setting up new ones, and at what base timing and RPM should I set them at...
I guess the best way would be dyno and or plug reads maybe even a Wideband O2 and take some readings and logs here and there at different settings. But I am leaning towards more a 62 FI settting usage overall, I have not look to see what they are, but I am thinking it may or may not have used the same camshaft?
HELP!
Right now at 18 base and 29 each point and 34 total @ 450 RPM she runs fine OK, I can feel more power over 1000RPM a much smoother motor and all, but just not to happy with the idle, would not say a miss as much as a noticable roughness to the idle... not the normal loppy I should be getting...
I can set timing by feel and see what happens as that can't hurt all to much, but the DWELL and GAP may be a issue... for sure its a 62 cam and coil and I would assume points also...
The distro was all cleaned up and checked no end play good and solid and oil as should be. Wires all clean and all contacts, even checked the Voltage reg and all is good. It tunes well no issues there, just seems a bit off the dwell when I first checked it was at 29 one set was 19 I do not recall what the other was but going to 29 on each one at a time then both I got 34.8 so I just fined tuned it... that made a hudge noticable difference... seemed to bump the timing up just about 2 so I lowered it back to 18 and well just seems a bit say loaded up at ilde... I am running a 6.5 power valve on the holley and the air idle scews adjust out fine... at about 13 on the vacuum gauge she seems a bit rough if I put idle at 15 on the gauge she much smoother and about 760-800 idle rpm, but still seems rough, If I hit 1000rpm its a night and day smoother motor?
Car was rebuilt, No air leaks, the vacuum gauge is steady and no needle bounce. New plug wires, new rotor and cap (ACdelco)...
I can easily figure total timing now that I think about that, so what is total timing on a 60 FI I know I seen that listed somewheres...
Just the way it should be, or am I being really picky, smooth idle is something I have come to be used to? Maybe I am shooting for too smooth a idle... She seems better at a much lower base timing but then seems to loose the snappy throttle respone... maybe just a trade off...
thanks all in advance...
