With the car in my sig and the mods listed if I added gt40p heads, what kind of hp gain would I see? Would it do much without adding a cam? Which would be a good cam? I was thinking maybe tfs 1. I would like a cam that makes power and is pretty lopey. Also would I need to up the injectors and maf? thanks

+40hp with the heads
yes cam will help. TFS 1 cam is not bad, but custom cam is better. Ford E cam not bad either.

You dont HAVE to do a cam swap, but it will only help.

stock injectors are fine.
76mm C&L MAF would be good upgrade.

might want to upgrade to a 155-190 lph fuel pump too.

what cam would make it run well and have a nice lope?

r.barn

look for a cam with bigger durration for lope.
a Ford B cam would probably make you happy or TFS 1

one more question. Should I have the heads and my cobra intake ported and polished or would it make much more diff? and with heads and bcam i should be around 265-270 hp huh?

+1. the gains u would c with those heads will be real good. u could probably crest the 300 whp mark.

would i gain much more by porting and polishing the heads and intake?
