I have aluminum Edelbrock heads. So really what I am trying to do is have a drive able torque monster that makes power up to 5500 rpm and idles well enough to run my A/C and has enough vacuum to run my power brakes. I'm running an automatic and 3.23 posi and this car will not be a drag car or a street racer, just a cruiser.
I'm late to the party here buuut... I have run a cam VERY close to this in a 351C. 190/200 duration at .050", .475 lift, 114 LSA. It was a GREAT torque and mileage cam. Idled smooth with high idle vacuum, and pulled well off the line despite a low rear gear. And with a Torker single plane intake, the good intakes of 351C heads, and 1-7/8" tube headers all extending the upper end breathing, it pulled from under 2000 RPM to 6500 RPM. Static CR was about 10.2:1 with iron heads. Ran premium on the street for almost 100k miles. Flat towed a small race car all over the eastern US, commuted to college, and used it as my daily driver. 19 mpg all the time on the interstate with a standard 3 speed C4 trans and no locking TC. That engine would beat 440 Satellites EVERY time in a 3400 lb Ranchero with a low 3.08 rear axle.
I absolutely suggest that you DO use this cam for your described uses of the car and engine. For a broad torque curve, this is a very good combo with the good breathing engine parts that you have extending the upper operating RPM range, and the cam and decent compression controlling the low end. With your AL heads, I expect you can optimize ignition timing better than I could with iron heads; I had to limit ignition advance to avoid pinging/detonation so was on the edge with DCR.
I expect you be around 425-450 ft lbs torque and 350-375 HP with this combo in your 400+ cubes. It won't be a 500 HP fire breather but I don't think this is what you are seeking.
It is not just for FI, IMHO. This is similar to the type of cam that several cam mfr;s generated in the early 70's after the Arab oil embargo hit, and everyone wanted a fuel efficient cam due to the gawd-awful gas prices of 80 cents per gallon LOL. Stump puller torque and good emissions comes along with the low duration, and the high lifts makes for good breathing to compensate up through mid RPM range.
