Re: (long) hei/advance curve opinions needed 396
zeke..yeah it worked pretty good when i first got it all on the road, but the timing has been jumping around and acting a bit strange for about 6 months or so. i have had to reset the timing 3-4 times (runon/dieseling at shut off-found timing to be retarded), and I know it is sitting there too far advanced now(not by my doing), as the car has been hard to hot start the last few times I drove it. that happened out of the blue, all by itself.
the shop did advise me to use something else other than the HEI in question, I guess because it was obviously used..i think they did some grinding to gain more advance, and definitely lightened up the springs, I remember them saying they had a hard time finding parts on the fly. its hard for me to say how good it was originally running power/low end response-wise, as i babied it for a while after it was built..the more i drove it and got used to it, the more i started jumping on it and thinking that it seemed a bit soft down low.
plugs could probably at least use to be checked or replaced, I will say that. wires were brand new taylor spiro pros, entire hei was a mystery, took it off another car i had as it seemed to be ok. cap and rotor were new (replaced) when it was recurved though. coil was not replaced at that time. carb was new, and used/jetted on the dyno (but i think carb needs some fine tuning too..its fat). even though its been a year, car did not get driven much.. i doubt if i put 3000 miles on it over that time span.
if i get the e curve + blaster 2, it will be a while before it gets installed anyway, i will likely play around with what i have for right now..i agree that changing too many things at once is a bad thing!
