I wasn't sure of the lift with the stock cam/1.7's.....Thanks. I am still leaning towards either a stage 1 or XE264 cam. Both should work and give me clearance with the 58cc heads, I was told by TFS that I could go up to about .530 lift, stage 1 is .499/.510 and he XE is .512/.512, still not sure which would be better choice for me, so I will probably go with 1.6's and one of those cams to save a little $$ that I can spend on a Bama 4-Bank eliminator chip.....Oh and the stock cam/1.7rr option isn't a bad choice if on a budget. The car will have stock mannerisms while making a little more power. The heads,stock cam and good induction will make around 50 extra hp and behave like stock.

Are you saying the vale springs on TFS heads need to be replaced with a .499/.512 lift cam or .512/.512 cam? Right now I have an intake from an Explorer, 3.73 gears, exhaust is 1 5/8 shorty headers into a 2.5in x-pipe into flowmasters. TB is 65mm and 70mm MAF from a 95 Mustang -19lb injectors............I plan on getting a Pro-M MAF and either 24 or 30 lb injectors....but the car is also an AOD car, not a 5 speed....it is also a daily driver.That's because the valve train that comes on the heads are junk. They'll handle mild weak camshafts but anything with an aggressive lobe will require new springs. I'd do 1.6's, custom cam and new lightweight LS style springs to match.
What intake, gears, exhaust, injectors are you using?
I've got an Anderson Ford PMS (series 2) for sale cheap if you are interested in dialing in the car yourself.
With my heads only being the 58cc heads and having stock pistons I can't go over a .530 lift or the valves would hit the pistons from what TFS told me, but my car is a daily driver so I don't want a real big cam, just a bit more power than what I am getting with the gt40 heads.The springs are ok for a mild tfs 1 cam. You start getting into aggressive lobes and fast ramp profiles and they quickly become garbage.

When I was talking with the TFS tech guy I told him I was using a stock short block 5.0 with stock pistons, I assume they have done plenty of R&D work with stock and modified 5.0's, he seemed very knowledgeable about what would work and what would give ptv problems, he did say I need to check ptv clearance but that a cam with under a .530 lift should work. He knew the length of pushrods right away and didn't have to look up the info.That's incorrect. The lift of the camshaft doesn't really dictate how 'big' it is or if you'll have p to v clearance issues.
All I have to do now is decide which one to go with.........what differences are there between one that is .499/.512 an one that is .512/.512? Is one better for low end power?Just run one of the cams you mentioned. You will be fine.
