I finally got the 355 out on the highway and am in the process of getting the advance curve dialed in a little closer. Some pinging under load. With the previous engine, which turned out to be a .040" over 307, the Magna Flow mufflers had a very irritating drone between 1500 and 2000 rpm. With the new setup, the drone is much less to the point of not being a nuisance. Not a race car by any stretch, but with the 2.56-1 rearend, it should be a nice highway cruiser.
