What are your thoughts on hood scoops, hood bumps, cowl induction, etc.? Back-story:
Several years ago I spent a couple thousand dollars on a reman engine and some performance parts for my (then) daily driver '91 S-10 Blazer. Unfortunately, whomever owned it before me did a quick and easy paint job on it and it wasn't long before the paint started peeling off and the body started rusting to death. I didn't have any more time or money to fix up the body so it sat.
I recently found a very cheap '89 S-15 Jimmy that has a much better (but not perfect) body but crappy engine. I have swapped the engine and transmission and am now to the point of putting the hood back on, but the hood will not clear the engine without some modification. On the Blazer, I cut a round section out of the underside of the hood and it was enough to get it to close, but it still rubbed. I would like to have a better solution for this truck as I now have the money to make this truck into what I wanted the other to be.
Because I know you guys love pics and video, here is a vid of the first diagnostic run: http://www.youtube.com/watch?v=hgQk0NU508I

I've owned a Blazer and a scoop would be non-functional. Costs $$ to make one look right, too.

It doesn't have any exhaust apart from the headers yet and I'm not happy with the function of the transmission yet.
It's heading to the muffler shop next week and then to get painted after some rust repair.
Edit: I'm not a fan of hood scoops and am looking at different air-cleaner designs trying to find one that is noticeably shorter.

They are about as short as you can find (and cheap, too!). I had a Mustang (302) with a high rise intake and 1" spacer under the carb, and that one was the only one at the time that would fit without chopping the hood.

If I remove it the stock fuel lines will not fit as the intake manifold gets in the way.
I have looked at the Edelbrock ones but can't find anyone around here that carries them. I was hoping to see one in person to get measurements before buying it.
I'll be driving by the shop today on the way to my guitarist's house; I'll stop and see just how tall the filter can be before it hits.

1) asthetics
2) clearance
It really depends on the vehicle that they're on, but I have yet to see a pickup/SUV with one that I thought even looked decent, let alone good. A lot of cars can pull them off and look sharp though. If I would do anything in your shoes, I'd do as low as a cowl induction type that'll give you the clearance you need. |

If I would do anything in your shoes, I'd do as low as a cowl induction type that'll give you the clearance you need. | If you build a cold air box and seal the carb directly to the scoop you can pick up the performance some. On my old 79 Z/28 I sealed a homemade airbox to the stock cowl hoodscoop (after cutting out some of the hood, and picked up a tenth in the 1/4 mile.
My other Camaro has a scoop purely for clearance reasons. You're just not going to fit a big block with a Team G intake under a stock hood. |

|  | Hey, what does this knob do? | | Join Date: Sep 2008 Location: New Hampshire | | | Be careful. Just because you can buy a particular scoop or a hood with one doesn't necessarily mean it'll be positioned in a pressure (rather than vacuum) zone. I've personally witnessed Holleys emptying the contents of their fuel bowls onto windshields at high speeds, despite every indication that the scoop's position "should've worked." |

The foam breaks down and you wind up sucking it into your engine. |

You'd have to have an incredible amount of vacuum to suck fuel out of a bowl vent. | | Thread Tools | Search this Thread | | | |
