What kind of cowl hood does it take to fit a tall single plane with the elbow and forward facing TB?

What about with a regular 4bbl TB and a bonet?

I am currently going through this right now. I'll tell you what I have,take it from there.
Super victor manifold,[same height as victor jr] 2" spacer from 4150 flange-dominator, dominator throttle body and a 2-3/4" bonnet .
I cut the center out of my steel hood and am now making side panels for the cowl scoop,with the hood on the car,I need to make the cowl scoop 5" high,24" from the back of the hood. This gives me 1/2" clearence.
I'm sure a 3" cowl would clear a single plane manifold with the throttle body elbow,I had an elbow on my manifold with no adapter plate,and the stock hood cleared it. It was one I welded up for a ford style throttle body,75mm,so it wasnt as tall as the ones I have seen for sale.

like these, will a regular 4 " cowl hood be required?

Guido

I still have not tested a hood on my car yet.

A friend of mine has aharwood liftoff cowl hood I want to check. If not, then I will probably end up going with the VFN 4" cowl. It has a long cowl on it so it would clear everything pretty good I think.

I have the holley single plane manifold with the four barrel throtle body on top, with a cover on it and it fits easily under my 3" cowl hood.
check out my pics on this board, they're under pics of D1SC on ZZ4

I've come up with some numbers from my current setup.

Weiand Street Ram 4" tall
TB unit 2"

I have zero extra room with a 2 1/2" non drop base air cleaner. When I use the drop base one with a 1" spacer to clear the linkage, I pick up about 1/4" of clearance. I might be able to pick up another 1/4 - 1/2" with a shorter spacer with the drop base.

So with a 2" tall Throttle body with the stock hood, there is room for a 4 1/2" tall intake with a drop base air cleaner with a 3/4" spacer to clear the linkage.

A Victor Jr is 4.58" high(#2900/2975)... probably a very iffy fit with the stock hood.
Super Victor #2925 is 5.5" ...1.5" taller than my current setup so with the drop base and 3/4" spacer, its only 1" taller than the current setup. Should be no problem for a 2" cowel or even something like the ASCD ram air hood.

The setup you are refering to will need at least a 4" cowl hood. Or a hevily modified 3" cowl. The drawback to a setup like this is how far the motor sits in the vehicle. The slope of the 3" cowl will run right into the t/b on your 90* elbow. Attached are some pics to get a reference.Hope they help.

BlownBird

If you need any particular pics, let me know. I will be more than happy to help out on this one.

Dan W

Blownbird, what intake are you using and would you mind measuring it for me? Run a strait edge across the center of the flange where the elbow bolts to the intake and measure to the end rails on both ends.

How tall is that elbow from the intake mounting flange up? Can you get another picture like the first one but get down a little lower just to the point where both fenders line up. Thanks

BlownBird

ok,i'll get some pics up soon. Don't quite know what you mean about "end rails", but i will take a measurement from the block to the top of the elbow, and the other measurements too.

BlownBird

well, here ya go

BlownBird

Ok guys, i think i have the shot's you are looking for! I am using a Victor Super Junior that is measuring out 14" from the block to the top of the elbow (the elbow is 6.5"). I have a 5.5" VFN fiberglass cowl hood. you can see how much clearence i have with it.

BlownBird

sorry, that last measurement should have been 13.5"
Guido, here is the money shot

BlownBird

After taking the measurements i believe a 4" cowl hood will work with this type of setup. And my intake is taller than most single plane's out there. It is setup for a raised runner head. Hope this helps you guys out.

BlownBird

OMG what a monster

Dan W

This is the measurement I was looking for.

picky picky.

D144John

Blownbird,that thing is wicked!!!!!!!!
Your elbow is a whole lot taller than the accel one,and taller than mine.
I cant wait to see that thing run.
John

BlownBird

John, thanks for the compliment, I introduced myself to you at the last GMHTP shootout. I was one of the guys that didn't have a car there,LOL. You will se me at the next GMHTP shoot out! I want to see your car there too, I hear you have made some changes since the last time i saw it. See ya around, Don B.

Dan W

Lol, sorry

With prices on thirdgens being as low as they are it is no wonder we are seeing people with money left over for exotic drive trains (myself included) but I am mostly drag related on my car. I hope to see your cars in GM high tech performance magazine. We are and drive the replacement for the 5.0 mustang dudes. say goodbye to the camaro and firebird! hell no, we are just getting started! My ride https://www.thirdgen.org/rides/index...ew&rideid=3980

BlownBird

Well, I don't know where you have ben shopping, but i've got WELL OVER $20000 in my car, not including the cost of the vehicle. I do believe the third gen's are great cars, but I do not think it is cheap to build a drag car. I do plan on having my mug on the pages of GMHTP magazine, I just have to put the car on the bumper a few times at the shootout, and i'm in

Dan W

I'm running a 9" in my car also... with art morrrison control arms... can't find a picture but it basically just has a tubular lower arm with another arm that mounts about 6" back from the front of the arm to a weld on bracket to the top of the housing. The upper is adustable in length to change pinnion angle. Very similar to the Lakewood arms you are using... I think. But you cant use a torque arm with my setup.

I assume that where the lakewood arms bolt to the housing, they dont rotate on the housing... so this with a torque arm that does not pivot on the rear end should create bind. What am I missing something?

that intake with the accel elbow and a twin nostril 58mm, think i could do it with a 2.5" ? i don't want the huge assed cowl hood.....kind of takes away from the street car image.

B4Ctom1

trust me I understand to the tune of about $7500 a year since 1999 spent on my unfinished car. it is not that its cheap to build a streetable drag car, and I know it because people turn over cobbled together stuff to us all the time and say, "build this" and we do and they pay, a lot. but just think what you would have if you would have started with a plane jane 1998 LS1 car ($$$$$), would you have only a fraction of "disposable income" to invest in it, than you have invested in your sweet bird? or better yet if you are like me, you would be faced with a choice of comprimise or wait till you can afford to do it right. Im sure (by looking at your ride) you would choose the latter, and wait while a few more summers pass you and your car by, so you dont have to comprimise. I love thirdgens so much that to me a thirdgen is not a comprimise, even as prolific as they are, they are still unique when built the way we are doing it. they are not the belly button 1st gens and 55-57 chevs we choke at when we see them racing, at shows, or in articles.
