Hemi camshaft questions

What is the more popular cam for a Brad6 , 525 cuin with a kobelco hh at 50% . Also have anybpdy tried cams with a 4-7 swap? Thanks guys!

 

Call sig erson he will hook you up, 4/7 is bull s#it

 

Call Chase Knight at Crane, been around a long time at cusom grinds in less than a week. Took 3-months to get me last Erson, maybe they are caught up now??

 

4-7 swap

A 4-7 swap cam may make more power, but the engine will fire on the same rod journal in sequence, which might hurt crankshaft life

 

like i said bulls#it

 

I'm With Eli,we Tried It,we May Have Got A Mile Per Hour More.it Definitley Was Not What We Were Hoping,and Not Worth The Money.i Think Most Guys With Your Application Are Running A Crane 296/500-114x Or 116x.there May Be Guys Flyin With A 4/7 Swap Cam But It Wasn't The Answer For Us.

 

Both cams fire the same rod journal in sequence,twice,-4&3 and 5&6 for the standard and 7&8 and 5&6 for the 4-7 swap. The only difference between the two cams is that one fires 2 cylinders beside each other in sequence at the back of the engine, (5-7 )and the other at the front, (2-4.) The only thing that it might effect is fuel distribution in the manifold. Most of the top runners that I know use 4-7 swaps.I don't know if it makes more power but one thing is, it make the motor sound a bit different.

 

Crane R296/500 R16 is a good all around camshaft for an alcohol engine.

 

We have been running a Crane 4/7 swap all year, but are putting a motor in the car tonight with an Erson Std Firing cam of the same grind. I have heard the motor "sounds" different also, but will be able to tell you if there is a difference in performance or sound real soon!
