Comp polymers upper intake

no experience running one.

the short runners are not designed to work optimally in the lower rpm range, so, in theory your hp/tq would be realitivly dead, or, out to lunch below 3000-3500rpm.
However, given that you are only running 130-135cc intake runner, regardless of what gets slapped on top of them they should make respectable lower rev performance.

My 'combo in the works' consists of ported E7's and a Tom Moss lower along with an aggressive cam. The cam was not designed to do much below 3500 and yet with the small runner heads it'd still smoke the tires from a 2500rpm roll in second gear(stock upper).

I've contemplated running a box atop my combo, but am not ready to dish out 300 bones to take advantage of a few peak cfm.

The stock upper flows mid 190cfm... before plunking down 300 bones, I'd have the heads flow'd to ensure that the upper is really restricting you enough to warrent the upper intake swap. Remember, peak lift(flow?) is only reached once per revolution, but "all" other lifts are utilized twice per revolution... keep that in mind once you get your flow numbers.

Again, the theory is that it'll 'kill' low end power, so, may not be something you want for a street car.

My guess is on a street car you'd not be happy.
Launching at 6250 on slicks and beating it up on the track where 95% of the run is above 3500rpm may be a different story.

Hope that helps.

Hartman Box Intake

Thats what they were before they were bought by Comp Cams. I've had mine for about 9 years now. If your motor is stock you'll not like this intake. You'll lose a lot of power down low. This intake is made for forced induction. It really wakes up then.
