I have read much about these cams.(blox type c)
but I got a doubt.
can take advantage of them with a stock block?

 

you probably gonna kill the motor running these cams with a stock block. they require higher compression ratio

 

I don't think it will 'kill' the engine by running them unless you have clearance issues. However, if you use them on a stock compression ratio you are going to lose torque all across the rpm band so there is no point in running them. Bigger does not equal better.

 

arn't the primary lobes the same as stock?

 

Nope

 

What block were you thinking of running them on?

 

It would help if you gave us enough information to actually provide an accurate answer - which block? If you are running an LS with a b16 head, then no, those are not the best cams for you. If you are running a B18C5 short block, then they would work fine with a tune and the appropriate supporting mods.

 

thanks for your help
i´m runnig a b16a2(stock).
For this engine what are the choices I have?

 

Blox A, BC III+, etc

 

Thank you all.
He was about to make a mistake if you buy the blox type c.
Bc III + I take a look at these.
If you know more brands please tell

 

You can actually run fairly large cams in a b16 if (1) it is built to rev high, (2) you have all the right supporting mods and (3) you have a real engine management system.

However, most of the time, for a daily driver, you are going to be better off with something like a BC3+. On a mild B16, that is always my first choice. It has a great mid-range and will make good power all the way to redline.

Don't skimp - upgrade your valve springs.

Beat of luck with your project.

 

thanks Top Ramen
I just want to optimize a little the performance. Without compromising driving on a daily basis.
