Thread: 454 build advice

Tweet

Hi, there. I would get over having a lumpy idle cam in the engine. Totally useless except for the sound if this is a street use vehicle you want to drive regularly. You will quickly tire of it. I would suggest a more traditional profile cam shaft and maybe talk to tech support at Comp Cams yourself and see what they recommend based on how you think you will use the car. I would play stupid in the call because stupid goes a long way to get the right advice from tech departments.

And find a local car performance service shop that has a rolling chassis dynomometer. They can tune your engine correctly in terms of fuel/air ratio and do any fine tuning of your fuel pressure if you are using TBI or other fuel injection. And they may give you advice on a cam as well. A Big Block engine that is set up for the max street use performance and uses a not so wild cam will give you trouble free service for a long time. I have had a couple of trucks I bought new with 454s in them, and the second one I still have and have modified it greatly. These engines are extremely reliable no matter how much work you make them do. And there just is not a sound from a car that compares to a Big Block. It does not need a lumpy idle or a loud muffler to make its statement to the public. When it idles at a light or in a parking lot, people will know what you have under the hood.
