It'll thump alright, but with an RPM intake, a 750 carb, and 10.25 compression I bet it'd run fine. Like Brent said, a cam in a 352 isnt going to be the same in a 416 or bigger. That thing is on a 102 ICL and relatively low lift, its not a high RPM cam. The early cam timing and low lift will make that cam peak around 5000 rpm with stock heads. I would expect my cam would be just a smidge milder in your motor because of the larger displacement.Īdvertised Duration: Intake / Exhaust 280 / 286ĭuration. Should be a hoot with overdrive and 4.30 gears and a locker. The car runs fairly hard for what it is and has no problem smoking the tire with a 3.00 open rear. To be honest, it's probably a bit overcammed but it's still fun to drive regardless. Todd, just to give you some idea of idle sound, if you're interested, here is a quick video of my car and a shot of the cam card. If the cam kit came with the lifters and timing chain, then whoever you bought it from will probably want it back like that, if they will even take it back at all. If you do go with the 270H, the peak will probably be lower (around 5000 as you say) depending on if the heads have been worked or not. There's not anything about these cams whatsoever that's good for a street build.Ī 270H or even a 280H would be a good cam for a 416, depending on where you want the peak to be. You absolutely do not need a 107° LSA, nor do you need 15° whopping degrees of split between intake and exhaust duration. Now with that being said, that cam card must be for a Thumpr cam. That 'one' is usually the smallest engine displacement in the family.Ĭylinder heads, displacement, you name it will affect how a cam works and where the peak hp rpm will be.

The manufacturers can not list the characteristics that the cam would offer for every single build iteration, so they just list it for one. The cam that's needed for a 352 is not the same cam that's needed for a 390.or a 427.or a 428.or a 527. One of the biggest mistakes that home builders make when they buy a cam is that they pay attention to the manufacturer's description. This is what I have installed in the Shortblock I guess that's no good when I'm really not going much over 5000-so do I need to get a 270 for my 416? Does that mean I'm not getting any power till I hit 2500 with this cam? If I were to just purchase a new camshaft could I keep the Hydrualic flat Tappet lifters and timing Chain and gears from the 295 kit or do I have to replace all? Thank you Well I guess I got the wrong cam installed too, the rpm operating range of the 295 Comp cam is 2500-6400.
