5.0 NA hood
 
1 Attachment(s)
I have been looking and measuring at my engine compartment and I have come to one unavoidable conclusion... The stock won't fit. I would have to cut out the entire center and sport a huge hood scoop in order to use the stock hood.
My question is what hoods are you 5.0 guys sporting that are not too over the top and give more room?
I like the looks of this one.

Hey Sebz. How did you get that nice curve in the cowl? I cut my hood today and it looks like a door wedge glued to the hood. Any suggestions?

What vehicle are the vents from? I like the way they look.

sebz 03-29-2015 08:23 AM

the vent look like old 90' trans-am one.

Rowen210 I add picture to my album. I will post a howto in the DIY section. I don't like the vent and you don't need it with a cowl induction.

I will probably make a mold of my Hood next summer (no headlight hood).

rowen210 03-29-2015 10:24 AM

The hood vents are from an 80s trans am. They were originally positioned as scoops but I thought I could turn them around to be used as vents. I am not sure if the vents are too much. My car will be mostly stock in appearance. I will be adding front and rear vales from a 95 M edition and fender flares. I thought hood pins, vents, and a cowl may be over board?

I can paint and smear bondo but I have never tried to make a one off hood. I was thinking about welding 1 or 1.5 inch spacers in the back to lift the cowl. Make a long triangle aluminum piece and tack it in to fill the gap. Then bondo or fiber glass in a smooth curve. Is this the best way?

sebz 03-29-2015 10:36 AM

I post a DIY, But if you realy want to continue the way you are.

Yes you have to weld aluminum all the way to the back. The hard part is to make it look smooth and symetric.

charchri4 03-29-2015 04:31 PM

I'd do it with fiberglass for sure but I like doing crazy stuff with glass. It is tricky to bond fiberglass with aluminum in a panel that routinely goes from freezing temps to well over 200 and not have it crack. Epoxy resin is better for this sort of thing than polyester or water based but it's also twice the cost and harder to work with. I really don't see any reason to make a long triangle metal piece, I'd just support it with metal so it's solid then bridge it with fiberglass.

A much bigger issue is you have to get the structure back in that hood to be at least as solid as it was. Any flex or twist in it as you open it and you are going to have adhesion and cracking problems in your artwork.

I would not use bondo or any sort of featherlite type filler. Stick with duraglass or kitty hair and try to use as few different products as possible. The reason for that is you want to have the fewest different expansion rates possible.

As far as the vents doing anything there you are right that is not the ideal spot for them but it's not the worst either. I could write all day on this and learned soo much about it over the last year but it's fairly well spelled out in my blog so I'll send you there.

Hood Scoop

I also run a 5.0L ford in a NA. I used a 99-04 mustang hood scoop to get the air cleaner clearance I needed. It fits great and it is low profile.

Hood issues with the scoop?

I have a similar set up, but the air on the freeway lifts the front of the hood up because the air gets in the scoop, and the pins must not hold the nose down enough. Have you had issues with this?

sebz 12-12-2016 04:00 PM

make a cowl.

Unfortunately I don't think I'm as gifted as you at body work. But if you're willing to sell goods I may be interested!

sebz 12-12-2016 04:35 PM

i can make you a hood but i'm in Quebec Canada.

I mean it just depends on how much you're in the Christmas spirit.. ;) yeah I'm guessing after your time, labor, + freight shipping it would get pretty expensive. Any ball park # in mind?

you could beat your hood into submission like this:

I like your style. Although I think it may be possible that's the same as this one...

nope, hammered into submission....

http://www.miataturbo.net/attachment...ine=1451893071

started out using a homemade bossing mallet. made it by welding a 1/2" pipe to a oxygen bottle cap. nice big radius. then went through an assortment of hammers, air hammers, rivet guns, slappers, dollies, and a leather shot bag filled with 50 pounds of lead shot.

these three pictures are very early in the process. i have maybe 12-15 hours labor on it. the hardest part was getting it to be symmetrical. after learning what i learned during the project i think i could do one now in 2-3 hours.

as for the ebay fiberglass hood... it wasn't available when i was doing this but v8 roadsters said they had one coming. couldn't wait. i seriously doubt that it weights 8 pounds. carnut had a fiberglass hood for his build that was supposed to weigh 16 pounds but ended up over 20 and didn't fit that well. he ended up not using it. his thread: 93 Miata LFX build
see post 109.

our build threads: we started on mx5atlanta.com but moved over to miataturbo.net for a wider audience.

on mx5atlanta.com -> Portabull's noname 96 LFX Swap

on miataturbo.net -> The Portabull LFX Build - Miata Turbo Forum -Boost cars, acquire cats.

i know it's not a v8, but damn. i love this flat torque curve. it's basically all there from 1000rpm on up. it drives just like a miata but faster. most of the time i shift around 4000, but the redline is 7200. you know, just for when you want it.

I hate to revive a dead thread, but which hood is the one in OP?

if it's custom does anyone here sell them?

sebz 03-08-2018 04:18 PM

The hood from the picture was a production hood (don't remember the brand). But the thing i remember is that it's not fit a 5.0l engine. The reason i made mine.

Hope that help :)

5.0MX5 03-09-2018 06:49 AM

It's a Simpson, this would be the hood of which you speak. Someone had one for sale on one of the forums in the past very few months. Sorry don't recall who/where.

I'm running a stock hood on my conversion. To do this you have to cut one hood brace directly over the engine. Now, I'm running FItech fuel injection but others have used the stock hood with the Ford factory fuel injection.

It's doable.

topdownfun 03-09-2018 08:17 AM

Maybe not relevant, but my stock hood fits perfectly with my 5.0 without cutting any of the webbing or adding a scoop. One of the benefits of using the SN95 engine with the lower profile intake.
