1965 352 cam?
I have a 1965 F250 with the 352. I have put a 570 CFM Holley carburetor and an edelbrock performer RPM intake on it, and would like to swap the camshaft in the near future. I am looking for street performance, and maybe a little bit of thump in the idle. Any suggestions?

Sorry you're going to have to dumb that down a little. I'm not very well versed in the world of camshafts.

No for sure number because the odometer says 50,000 but the service stickers have in the 70,000s so I'm guessing a little over 100,000

If you are unsure of mileage but figure it is over 100,000 then you would be best suited to doing a rebuild while you do the cam swap. You want to feel some horsepower get rid of the stock manifolds and opt for a set of headers. You want to know if a particular cam will work like the Comp? Call their tech line or send them an email. They will tell you everything you need to know. If you change a cam then you will need to change valve springs and set the required height or you probably wont get 5 miles down the road. That particular cam has a lot of lift on it.....

That’s a lot of lift for stock springs and valve setup. You would be ahead of the game to do a complete rebuild. Then there is no question on what you have and it will live a long and happy life being done right.

I hope I can type this to help you understand what you are getting into with that much lift over stock cam. Lets say your valve springs are 1 1/16 inches tall. The spring can only compress to 9/16 of a inch tall before the coils start touching. Now with the current cam it only opens ½ inch giving you room for just 1/16 of a inch. Now you install that nice big cam in there that will open the valves 7/8 of an inch, what happens next. You start compressing coils together and they have no place to go. Well they leave a nice big hole in your motor and pocket book. There is more to it then using the right springs. Valves have to be cut X long and push rods and rocker arms need to be changed out with that big of a cam. Can it be done? Yes it can, you just need to look at the hole picture before doing so. I hope this help.

If all you are looking for is cam thump then you can go with a cam like Elgin's E963 go to competition products and look up. Lift is modest at .514/.514 but has loads of duration. If you are running a/t then you will need a stall converter. Also, as above post mentioned you have to set up valve springs and check geometry of valve train for long life. Not the best grind for performance but should have a nice lope if that is all you are looking for......
