Re: My new Tq monster 383

I'm wondering if 24's will be big enough. Also, 1.6 rockers will help as that duration/center line is good for torque but more lift, (within reason), never hurts.

Re: My new Tq monster 383

I using 1.6 CC Ultra Magnum Steel full Roller rocker arms.

I looked around and 24# should work fine I t not a 7000 RPM motor so I should not need that high of a fuel flow for 5500 RPM motor.

If not I be buying anouther set of injectors LOL.

Re: My new Tq monster 383

I pluged the numbers im for the next larger cam 60102 it makes less power with the same motor set up I dont need a 7000 RPM screamer a 5500 max every now and then type motor.

I have to pass Ca smog with it.

And what I read I do you dont have to use a aftermarket I alreay have a chip from the last can should work they say the cam I goning to use can work with the stock tune also.

Until I get a custom made chip.

Besides gives me some more time to see if the 24# injectors will be enough.

Be aware, the non pro versions of these simulators are only good for comparison between different combos;
real world results may vary from predictions

Some are too scared to put their engines on a real dyno to find out what it actually makes ;
preferring to claim the " estimated " results
