Take a look at this, 1969 Chevelle Chopping Exhaust Cold Start Cammed!
There is no car enthusiast in the world that does not like the classic American Muscle car, and for many of them it is the car of choice, as you probably have seen the videos here about the huge Scandinavian muscle car following.
One of the greatest features on these cars has to be the symphonic sound that they produce from that huge displacement and the V-8 configuration, and once you install a pair of exhaust pipes with bigger flow, they tend to “sing” to us the greatest symphonies.
As you probably know, before the engine reaches its running temperature, all those sounds are amplified and are mixed with the rough idle of the engine and the whole thing sounds even better, and this is why we decided to bring you a video of a 1969 Cammed Chevelle’s cold start, so you too can enjoy the pride and joy of this owner, so turn up the speakers and play the video.
1968 dash, 1969 door panels and 1969 exterior. With my old L72, 4 speed Chevelle I had the idle set at 1100 rpm. It went well over 175K miles with nothing changed out except a clutch disc, timing set to be safe and one valve spring. The L72 and L78 engines do need heavier than stock valve springs if you are turning 6500 and above. The springs won’t keep the valves in contact with the valve train up there and the free fall slam shut, eventually pounding the keepers through the retainers and dropping a valve. That very often windows the block as so many of these engines did when fairly new. Just a little tip for those who like rpm.
Well it’s a 1968 the key is on the dash…..
