Cam suggestions for 383 build
#11
I just saw this and really don't care .But since you ask ,I would say no ...You never get identical results on two of the same motors. In play land yes .In the real world ,no ..
So what are you implying? That two nearly identical engines one built in 2006 and the other in 2012 can not yield the exact same results?
The details in this case do not point to shenanigans by sprink's builder.
Looks to me that a good recipe was copied. Where was the magazine engine built?

Not a arbitrary limit. The rpms I stated are where the boat will run fastest. Will run out of 'steam' past that.
So, with the XM270HR it will run fastest near 5k with a 383 and 5200 or so in a 350. Both having decent aftmk't heads (vortecs included) and exhaust.
That's real life results.

edit in: if you want to run faster and at a higher rpm you will need more cam.

AC Crooks - you are correct about the HP and that smaller (212/218) comp cams. I know you know your small blocks and that proves it. GMPP's 425HP motor uses better cylinder heads and 383 cid's and a larger 222/230 HR cam. As a note, Their Vortec single plane added 20hp over the highrise dual plane to get it to the 425.
