Ok, i did a 351W swap in my 88lx, but I still have a few questions, I used a stock truck 351W, it's slower than my old 5.0 with bolt on's. At least it runs, so now I'm working on heads, cam and the rest of the bolt on goodies. I'm new to mustangs and have a lot of stupid questions, but I hope to be enlightened, show me the way of the force, fox body Yodas!

Do 351W and 302 HO motors share the same firing order? 13726548?

Are 302 and 351W cams interchangeable? I have a B303 I was going to put in my old 5.0, will it work in a 351W?

What is a 351M? I don't know what the M stands for!

Does Fidanza make a lightweight flywheel 157tooth 10.5" clutch that will fit my 351W?

If I use a Trick Flow EFI intake on my 351W can I use my BBK 75mm Throttle body on it? (that I have on my old 5.0)Or do I need a 351W specific TB? I don't know if the openings are the same on the aftermarket intake, or if they all have the twin throttle body opening like my stock truck 351W has. The trick flow add mentioned a 75mm opening, so it sounds like my TB can fit.

Does anyone know what size injectors come on truck 351's? I think 24lb, or 30lb?

What would be the largest cam I could run with stock deck height? I heard i could run a B303 with 1.7 RR's without a problem.

I don't live near a track, so I really am looking for a street car, what would you suggest would benefit a 351W , I'm looking for mostly bottom end power and torque for quick out of the hole for Stop light encounters, so any suggestions on what cam and heads do the most for these motors, I am open for suggestions on what you guys think, I was looking at the following:
Trick flow intake with my 75mm TB and MAF, ECM tune.
AFR heads
B303 cam, 1.7 rockers (If it does indeed fit my motor) IF not, then a cam of similiar profile.

Thank you for any help and answers you can give in advance.
