It is worth a couple hp. You can buy a new cover or cut yours to look like this: http://www.ecklers.com/product.asp?p...dept%5Fid=1756

Being ready to move to the '87 stock intake, I am quite interested in feeding my monster.This is what I would expect.
I'd like to know, where is that showing?
What is chp? Oh, crankshaft HP?

YES it's worth it because it will take a total of about fifteen minutes and it doesn't cost anything other than a rattle can of black. CHP is Crank Horsepower. It will get you a couple of ponies for certain, enough to feel a difference, absolutely not. It all starts with one stupid mod then it's a converter, some gears , a stroker then a little spray

Yes "chp" == "crank HP".
You won't likely "feel" a 10chp gain and maybe not even a 20chp gain but it will show up in 1/4 mile time slips as trap speed increase, assuming you can get consistent passes and the weather is the same between tests. That is, 10chp == 1mph gain at the traps and about .1sec off the ET.
There are time slip data and two dyno pulls on my site.

I would say if you are just going to cut it, go for it, but if you are going to spend 50 to 75 on a air filter element I would wait and spend 150 on a used claw and start there if you care or you are only having high hopes or feeling like a mod!

the open air lid will serve to dirt-clog up your filter and nothing positive that's even worth mentioning.
i put my homemade one in the basement, and will give it to the next owner of my '90 when its sold.

Is that a big block?
