That looks like fun!

I haven't heard of that brand before...
They're fairly new as far as I can tell but I've heard good things about them. Everything looks very well made from the hardware to the wire harnesses. I should have the old tpi removed shortly and get the motor all cleaned up and ready for the swap. She has been sitting for quite a while and desperately need some TLC.

Thank you for the tip! I got the weiand speed warrior intake at the recommendation of the guys arty Holley when I was shopping for different systems. Although I was kind of looking forward to getting a cowl hood... lol
I did see some dual sided carb hats too. Do you have any experience with them? They seem to be quite low. Il have to do some research on what the cfm is on those before I make a final decision.

You should be good with the Warrior intake. Another issue you will have is the distributor. You may find it necessary to either install the intake and distributor as a unit, or bore the hole out for the OEM distributor, if you can use it. Check with the manufacturer about the type of distributor you can use. The OEM unit is a HEI, but can be incompatible with some TBI units (Holley Sniper for one). The white wire at the coil input is the tach wire.

This will give you a better idea of what I'm working with. Not so mild and a 4l65 trans. The motor is a gen 1 406 from 1970. I see that I have some fab work ahead of me. Your hood looks beautiful! Very sleek.

The Caddy intake is designed for a 2 bbl TBI, and probably not flow enough for the above unit. My shorty is about the same dimensions as the Caddy, and is only good to about 250-300 HP.
I definitely need more than that. I want as many cfm as I can get. One less thing to deal with when troubleshooting... I'm hoping to see close to 500hp when all is said and done but I'll settle for what I can get.

Pro Charger makes one, and I believe Holley, and Spectre do as well. Engine Masters did a comparison, and other than the low profile, all of the constant diameter elbows worked about the same, as long as the hat was aimed toward the front.
I may have found the solution to the height issue and the lack of airflow. This unit will pass 1400 cfm and is available in a 180,135, and 120 degree configuration. Too much is just right!

I always loved the look of the TPI intake. They are great for low rpm torque but fall short once the revs build.
That new system should work great and probably improve top end power.
Fred has a lot of great info and ideas.
That he does! Truly invaluable to say the least. I've learned more in the last 24 hrs than in the last 3 months.

I'll be selling that pretty tpi system with the ECM as soon as I get it pulled. Maybe I'll recoup a buck or two.

dual plane will make more low end torque than TPI. TPI shines in the 3000-3500 range.

there is no such thing as a 4L65. it's an internet myth that 5 pinion planets are stronger than 4 pinions. They are actually weaker and if they are non-gm 5 pinions they are total garbage. Not saying that GM 5 pinion are bad, but they are nothing special and I wouldn't waste money on them. The OE high energy band is superior to any kevlar band, more marketing "hype".
Well it seems that I'm an unfortunate victim of all that "hype" considering that's the hand(and trans) that I've been dealt. Thank you for pointing out a potential weak spot in my drivetrain though. Il be sure to pay special attention to it from here on out.

Where are you going to put the filters? If you are using two sides, 3 inch should be sufficient for intake tubes. The fewer/shallower elbows you have for the intake tubes the better. You might be able to put them under the front of the hood, and have louvers or NACA scoops on the hood (like an old Mustang). You need some kind of tray under the scoop to keep water off of everything.

If you use the skinny hat, you may be able to use a single plane intake manifold if it is not too tall. That would give you more top end performance, but the bottom end will suffer. If you go to a single plane intake manifold, you may need a higher RPM stall speed converter.

Hood scoop from a mini cooper. I definitely need to work out a drainage system.

@Shammoosnewdriver If you don't mind me asking, why are you getting rid of the TPI system? I have one going in my 91 wagon, so I'm curious why you're swapping it out.
There's a built 406 in the car now not the factory motor. The ECM is from 1915 and is programmed with smoke signals and tribal herbs. I wanted something from this century that had a bit more tuneability and would make more power. From what I've heard the tpi setup won't do much more than 400 hp. I'm not sure where the previous owner got these numbers but I don't want to leave myself short at the end of the day

He has a 4L60 aka 700R4. Someone has thrown some 4L65E parts in and called it a 4L65. Notice there is no "E" on the end of what i wrote. Material is not equal (powder metal on the 5 pinions). like I said the OEM 5 pinions are fine if you have them but they are NOT an upgrade over the 4 pinion. absolutely stay away from after market 5 pinions.
It's an upgraded 4l65e as far as I know. I will verify that asap. This car has been around for quite some time so there might be people that know things that I don't. Any constructive info is greatly appreciated.

As noted your car was the non electronic trans and the previous owner put 5 pinion parts in it .
That making it a NON E 40l65.
Not an actual production part.
Did the original owner mention on going issues with that engine?
A deep dive on old threads might be a help to you.
Oh yeah. I have them pinned on my home screen. I'm still in touch with him. He just now responded and said that it was originally a 4l60 out of a 93 occ. The main reason for the efi upgrade is the amount of grief he went through over the years. I want to actually drive the car not just throw money at it.

I would suggest you make a project car build thread for this. It'll keep all of your content in one place, and if you ever need to sell it, provides a great spot to point people to documentation.

Don't worry about the transmission for now. Get it running, make sure the shifts are crisp but smooth, and you'll be fine. Eventually I would get a line pressure gauge and monitor for fluctuations in line pressure which will quietly kill your trans before you feel it.
Excellent suggestion. Thank you for the trans info also!
