Ok here is what i have:
86 f150 302
Stock block 40 over
edebrock heads PN 60379
Mass air conversion a9p ecu
24 psi injectors pro m75mm calibrated for them
dynomax long tubes 1.5 2.5
msd 6a
2200 stall from an 84 svo stang. Aod shift kit.
32 1150 15 Bfg all terrains.
Old Cam wolverine 194 204@50 .424 .448 115 lobe sep
Stock intake.
My best time with these items
60ft 2.2 15.5 @86.37mph
NewCam mustang Ho roller cam 210 210 .444 .444
Edelbrock truck intake
I installed the cam straight up dot to dot.
Now my best time 2.4 60FT 15.7 @ 87.5 mph!!!!!!!!!!!
My top end is great pulls hard from 3K up to 5500
but below 2500 its adog! I would hit it at the track and it seemed like i was barely moving as soon as it hit 3k it would wake up! MY off idle torque sucks compared to the the flat cam but with the ho cam I can be going 25 mph in first nail it and goes side ways big time and pulls very hard but from a dead stop nope! OK but i dont think its all the cam my truck is now running like crap also below 2500. It idles real bad, in the moring when its cold it barley wants to stay on and once its warmed up I can almost smell raw gas. If I diconnect the meter its smooths out the idle and everything. I dont think I have a bad meter becouse it was running just fine before i took it all apart.
Here is the other wierd thing. It does not ping at all. before i changed anything I had the timming at 14deg and if i used anything but premium it would ping. I have the same timming and reg and it does not ping at all. I tried a different computer but it does the same thing. I must have a vacume leak somewhere but i cant find it. ANY IDEAS ANYONE PLEASE HELP!

 

Just a shot in the dark here but you might consider the lobe center angle of the new cam being lower then the Wolverine you had in there.

What are the complete specs of the two cams?

With the bigger cam I bet you have a lower DCR, so that might be why you don't ping now. This loss of compression also effects you low end. The crankshaft rotation in degrees related to the intake valve closing ( wich determines the DCR from mechanical compression) can also reduce the actual CI the engine see's. If that makes sense.

 

Old cam 194 204@50 115 lobe sep 105 lobe centerline .424 .448
H.O. Cam 210 210@50 115 lobe sep 115 centerline .444 .444

 

Yeah it looks like the lobe centerline is reducing you DCR. Thats my guesse why your cam isn't responding on the low end. Just my 2cents.

 

The "HO" cam has a pretty soft lowend as you mentioned.Most of the Lightning guys that use it install it 4* advanced to help get some lowend back.

Your idling/startup issue deffinately sounds like a bad/dirty maf.Thats exactly what my car Tbird did when the maf went bad on it.
