    hey lukerz.heres a nickels worth of advice from a body man with almost 15 yrs exp.,just buy one either a complete hood or a bolt on scoop.trying to fab.one outta steel will take forever.its a PITA to weld and try ta smooth in that much area on a hood(they like to warp when heated during welding)dont try to mold one in w/ fiberglass,it WILL crack.money back guarantee.on a jeep cherokee i had i trimmed a fiberglass scoop and bonded studs under it and bolted it down.it was the absolute easiest way to go in my case.unless you just like to work for days on end for results youll prob not be happy with,take my word for it.

    From my 34 years of experience with building and repairing 4x4's, Pure Insanity is speaking some wise words. As they say, been there & done that! Have learned the lessons that he speaks about well.

    Thanks for the feedback. Could you tell me what I should get. I would prefer bolt-on. Where would I look online for this? Also what is the difference between where the opening is located, font or back?

    look in jegs or summit racing.my personal favorite is the cowl induction scoops.i like the look of them.if you go w/ a front facing scoop like the aero scoop,youll need to make sure you get the plug for it for when it rains.otherwise as you drive youll be filling the engine compartment w/ water.on something like a blazer,well mine anyway,theres no peformance advantage to haveing a scoop because theres so much room under the trucks to begin w/,i get plenty of air from the underside.be aware that if you go w/ a scoop,you will prob lose visability.thats why i like the cowl ind scoops.they only stick up high in the rear,so theyre easy to live w/.stay away from the abs plastic scoops,stick w/ fiberglass.my old room mate had an abs scoop on his camaro,about once a week it would break and fly off.just about everytme he passed a semi.to me scoops are only for looks unless your building a race car,and trying to force air down the carb.yes they do release heat,but IMO not enuff to make a difference.im speding my $$$elsewhere for now on mine.sooner or later ill go w/ a full fiberglass 4"cowl hood from harwood.

    I run a Harwood cowl induction fiberglass hood, but do primarily to release heat as I tow a 24' travel trailer and work the engine hard on mountain passes up and down the West Coast. Have found my engine runs 10-15 degrees cooler on long pulls. Agree with Pure Insanity, stay away from ABS and use a good quality fiberglass. Have seen a K5 with a 427 L88 style hoodscoop and if I can ever find out where he bought it, I'll be getting one of those. Looked much better then the cowl induction hoods.

    10-15 degrees cooler!that much huh.my buddys truck didnt change much at all.altho his truck is a 90 model 454 1 ton.that sob will make the hood steam in a heavy downpour.the bb just puts off alot of heat,and its kinda full in the newer model eng compartments.

    oh yea BTW the same friend had a L88 scoop on his last big truck.sweet truck 73-91short bed step side on 44 swampers
