Title: Stage 4 or stage 3
Post by: shysterorange on January 24, 2019, 08:16:39 PM
Have stage 4 kit, but want torque at 2000 rpm. Have 468 RS as replacement cam for 515. Have heard stock heads and throttlebody are better for straight up torque curve. Anyone running a stage 4 m8 with a cam swap that has had great low end torque results? Dont care about 4000 plus rpm...cant decide on using cnc ported heads and tbody.

My stage 4 build, all HD, runs a HD stage 3 cam and has the torque curve you want.  It turned 128/128 on dealers dyno.  Runs great, no sumping issues noted, and has a decent low end.  Good luck with your choice.

It was a 114 to a 117. 110.5 tq at 2624 RPM. Max tq of 128.9 at 3663 RPM.  Over 100 tq at 2236 RPM.  Nice flat tq curve all the way to 6K.  Hope this helps.
