I thought that by going to a bigger tire I would get a little better gas mileage, you know lower RPM's? The engine has a little mis to it at idle and through out that I cant track down and figured the best thing to do would to get a new dist. then go from there. The thing about the DUI dist that I like is that they claim it to have a custom advance curve to suit your needs and better/instant throttle response. I like the MSD Idea but will still need a new dist. I am going to check and see if the price is around the same for the msd and new dist. compared to the DUI dist.If it comes out around the same I might as well go with the DUI because I dont have to find a mounting location for a box and run wires. The motor is not that bad all it needs is a little tuning to bring it up. I know these years of small blocks are not horse power monsters because of the restricted heads/Induction but I am not trying to race the burb. I just want as much low end as I can get for pulling a trailer and getting around town.
