I would put a timming light and vac gauge on it to see where its at

magna flow or Flowmaster, Dynomax? Which do you think?

resonators are extra muffs that are on the tailpipes as they pass parallel by the leaf springs. many diff types & (want no neckdown on the ends where the nipples connect to the body and louvers punched from the inside to the outside). On the regular muffs further upstream there have been good reviews here on the "hemi" dynomax super turbos. What Scratchnfotraction said on your timing put a light on it & see where you're at.

thanks my friend! I'm on it today when I get off work. I checked last night and it looked like 36 degrees

i was told that although my block is casted in 70 that it may be a 71 440 due to it being casted after June. HELPPPPPPPPPPPPP!

Yes the blocks typically took 4 to 6 months from the casting date to being assembled motors installed in cars. sine the 71 model year cars would have started assembly in August it's safe to say they will be 71 check the vin on the motor at the back above bell housing

What is the HP rating for a stock 440 engine out of a 1970 NewYork Chrysler
