Just to update this thread, I put the ported e7's and the stock Mustang cam in the truck and it was definitely worth it - given that the cost was nothing.
The cam really moves the powerband up in the rpm range and while it does give up some low end power; the truck probably has 1000-1500 more usable rpm and it really wakes the motor up. Freeway on-ramps are now really fun.
When I first did the swap the truck had some problems idling and with stumbling when I'd first step into the gas - but the engine seems to have "learned" the new cam and heads and it idles and drives like stock now.
Lessons learned -
1. You do NOT need to rewire the injectors even though I did. They do fire in batches, but the batches aren't left side, right side like everyone thinks - they are 1,4,5,8 and 2,3,6,7. So the bottom line is that the computers/injectors don't care if you have an HO cam or not.
2. You do have to change the firing order on the spark plug wires.
3. Buy a truck specific cam if you've got some extra money to spend. The Mustang cam is good, definitely better than the stock f150, but I'd bet a truck specific Crane grind might really be nice.
I'm looking to stab my old 1993 Stang cam into my dad's 1993 F150 5.0. The F150 forum guys aren't helpful - so here's the question:
1) Is a 1993 5.0 non-HO block a roller motor?
2) Besides swaping the firing order via the dizzy, will I have to re-wire the injectors? (Its a bank fire system)
3) Will the Stang cam throw off the truck computer?
4) Is the Stang cam a good grind for a truck that will do some light towing?
5) Has anyone here down this?
1) some are, some aren't, but if its not it still has the "posts" that you can drill and tap for the girttle. its easy to do.
2)no
3)no
4)idk
5) YES, i have seen this, i have done this
and plus your truck will sound better, changing the firing order makes a difference in sound imo
I'm probably going to do it next winter. I have a 1995 F-150 with roller cam and mass air from the factory so it should be pretty easy. I have the stock 5.0 cam left over from my Mustang and next winter I want to replace the timing chain so it'll be around 140,000 miles then. A great time to put that cam in. I pull a 4500 pound trailer every day so this should be interesting.
