so would you say that i should at liest have a 2500 stall to run this cam?

 

yes, 2500 would be a good start, 28-3000 better

 

In a 5.3, Id go 3000-3200 IMO. I have a similar cam in a 6l 4wd and run a 3200, but the cam was designed around a 3000. I had a TB that stalled to 27-2800, and it was a little too small

 

why does the trailblazer stall stall so high compared to our stock ones?

 

they are probably smaller. i have never owned one other than what is in my trailblazer but i would imagine that is the answer.

 

They are the same size physically, but they are designed to be behind a 6 cyl not an 8 cyl that makes more power. The more power you make the higher the converter will stall

 

 

its like the old days with Opel's converters behind sbcs. small powered motors and stalls then larger powerd motors with same stal will stall higher. since a stall converter goes by a motors torque and this is how you get your stall speed. thats why companies give a range of where the stall will stall unless its custom for your application

 

ah that makes sense, a higher powered engine will push something furthere than was built for a weaker engine to do, thanks, heres the the fuddle 3200 that is in my house calling to be installed

 

right on!!!!!!
