I wish I would have seen this thread earlier. You and I are running the same cam and I can tell you that this thing will make some power, I'm on 275/55/R20's with heavy akuza wheels and Z71 setup and I put down 310/301 on a Mustang dyno before running into fueling problems. The cam can definitively make some power.

ya thats what everyone on here and outside of here are telling me. the first dyno run it was at 219. i just had a bullshitter for a tuner was all. im not worried, Area47 is tuning it on sunday so i know my numbers will be higher. i just thought it was funny that i made the tuner retune it and according to him he didnt changed any settings but it went from 238 to 272 lol some people, i tell u. it hauls ***** at 272, i couldnt imagine what the seat-o-meter will feel like if i got 310

With stock heads you'll need the 7.4 pushrods. I'm running 243 castings milled .030 so I went with 7.350. Comp uses the stock base circle for all their cams I believe.

yes thats what i put in and was told m=by both comp cams and summit racing. in the beginning of this thread there was some concerns about whether i had the right pushrod length thats why i was asking. ur the first person to comment that actually has this same cam. so if ur making 310 with milled heads, what do u think i might make with my stock 862 heads and current mods? how much hp did the 243 milled ones give u over a stock head?

Couldn't tell you, I didn't get it dyno'd before I did the mods, and I did them all at once. I don't think it will hurt you much since the cam has a pretty low lift. I'm planning on going bigger with the cam at some point in the near future, and I got the heads for less than $400 already milled. My 310/301 was at 5400 RPMs, when fuel pressure went from 54psi to 32. The cam gives a really nice HP/Torque curve.

I also went with .030 (I think) thickness head gaskets to bump my compression to around 9.9:1 instead of 9.5:1
