We have made some real progress on this setup. After doing dozens of them, tweaking along the way this is the New Standard of Mopar Power! Same cam as before, our hydraulic roller cam with 239/243 duration at .050" lift. Valve lift is .550/.560". Compression is 10 to 1. All the same as before. Same heads, same pistons, rods, crank. Now for the CHANGES! We have some new chamber mods that are doing well. So well in fact that we now are running 4-6* LESS timing than before. That's a good thing. It shows we are running with a better flame travel. The other BIG change on this combo is the addition of a FAST EZ EFI 2.0 T-body injection system, with dual sync dist and full ECU timing control. This is the ticket. Its all in the results. 547HP and 562TQ!!!! Yes 560+ torque out of a MILD streetable SBM setup. Still want more? Ok. Stay tuned, as this combo has even more in it.
