So Im feeling pretty defeated becuase as we all have found ourselves scratching our head with a decision we made that didnt end up as we thought. But I dont want to give up, just gotta find the right way to turn this around.
Basically the shorter version of this story is when I switched over to a 351 roller cam engine and AOD, i was pretty happy with my results. For a couple weeks until i twisted the input shaft on the AOD. At that time my setup was a 351W, GT40 tubular intake, RPM heads, X Cam, longtubes, Xpipe, and 2.5" straight through exhaust. Car made 305HP/360TQ to the wheels after being tuned. Again after 2 weeks, the input shaft twisted.
I got the AOD rebuilt for an Edge Racing Non Lock Up style converter and upgraded clutches, servo, etc. However after this numbers dropped to 290HP/355TQ to the wheels. Also, felt like the car lost alot of pull.
Was that way for a looooong time. I had been having trouble with the car running right for a couple years and decided to go towards the simpler holley sniper EFI. I had been told that my engine would actually do way better with better airflow since the GT40 intake was fairly restricted compared to aftermarket stuff.
Switched over to an AirGap intake and the sniper system with full electronic timing control. Had the car tuned by the same guy who tuned it before and sadly the numbers are WORSE! Came in at 284HP/315TQ to the wheels. And yes you can really feel the difference. car feels sluggish low, and at higher speeds as well, no pull really. Heck my 2017 F150 5.0 feels more fun to drive right now.
I started looking up top end packages form edllebrock and comparing my setup to theirs and even their 400HP package, the only difference is my cam. they use the RPM cam while i have the X-303 cam. Im not sure what my commpression ratio is tho, while eddie advertises their setups as used on a 9.5:1 compression ratio. The 450 HP package uses the ECNC heads and rolling thunder cam.
thinking at this point to change out my cam, and possibly switch back to the Lock up style AOD, and hopefully a hardened input shaft will be enough to not break.
Any info/advice/encouragement is appreciated.
