Cam Choice
I'm still in the process of rebuilding the 302 on my 94 F150 4X4 and am looking to upgrade the cam. I have it narrowed down to two cams, both from Comp Cams:
35-512-8 = 258 int/264 ex Adv Dur (206/212 @ 050); .480/.480 lift
35-349-8 = 264 int/270 ex Adv Dur (212/218 @ 050); .512/.512 lift
As mentioned, I'm running the 302 with MAF. It's getting bored .040 over. The exhaust will be either true dual with long tube headers or SIDO with shorty headers and a 1 1/2 inch Y-Pipe. Either system will have high flow cats. Other than those couple of things and the cam, the rest will be pretty much stock. I plan to do a spring upgrade on the heads to match the cam as I don't really want to trust a cam upgrade to valve springs with 135,000 miles on them.
As far as truck use: The truck will be a daily driver, so it spends quite a bit of time on the pavement. However, I live out in the country with a lot of gravel and dirt roads that can get pretty nasty on rainy and snowy days. I don't do much towing with it now, but there is the possiblity of more towing down the road.
The reason I posted another thread on cam choice is that both of these cams have been mentioned as a great upgrade to the 302 motor. It's been equal enough that I'm really having a hard time deciding which would work best. The folks at Comp Cams have suggested both. So, I'm looking to see what your opinions would be, especially from those of you who might be running either one of them.

If you want upgraded E7TE heads, check out www.thumperoforangepark.com . The .512 lift cam looks like it may be on the edge of P2V clearance issues...the .480 would be a safer bet to prevent contact.
