GM 14097395 Roller Cam Specs ???

[Green Machine]

Looking at the HT 383 Camshaft (14097395) roller cam. Llift is .431/.451, duration @ .050 is 196/206 and 112 lobe sep is one set of specs I have found. Looks like it may have a 108 intake centerline for 4 deg advance.

Another set of specs I have found is lift and dur the same but it says 109 lobe seperation and no mention of advance, big difference between a 109 cam and a 112. Anyone got the true skinny on this cam ? Also the advertised dur specs seem out to lunch, something like 288, can that be right ???

Also will this cam work with stock valve springs ??? Thanks.

This cam isn't any great cam, it is a good lowend Tourque cam for the 383, Peak TQ on this cam is about 3300rpm, if your looking at this cam for a daily driver in a 4x4 &/or for some towing, it would be a good cam, if your looking at it for a perofrmance cam you can do much better, Also state what heads you are going to use this cam on. Also note that being this cam is a roller and requires different Valve springs than going from a traditional hydraulic cam. The lift isnt anything sever so it will work with most heads.

You should state what you have (vehicle, Engine, transmission & differential gearing) and what you are going after. Also year of Block you have, newer roller cams dont work to well in earlier non roller blocks.

Well, I have found a low mile 305 from an 89 Camaro pretty cheap. It has the factory roller and still has the fuel pump boss. I will have to change flywheels and add an intake and carb, but I would like to replace the factory 178/194"peanut" cam with something a little better.

That GM cam seems about right and can be bought as a new pull for 50 to 60 bucks.

Note this is NOT a long term runner, but in the middle of doing complete frame off on the body, very expensive, not much money for $2-3000 engine right now and I want to get this going by June.

I need the real specs to be sure, big difference between a cam ground on a 109 Lc and one ground on a 112, too much overlap will hurt my gas mileage.

I would say that the price is right and according to this description on SDPC2000.com sight its sounds like it might be a good setup.

I am considering this cam to replace the factory cam in my 2000 Escalade which has the L31 5.7 Vortec V8.

I wonder if I will have to get a tune to make it run correctly.
