See if Liberty works on the Nash. They are well known for manual trans improvements. Yeah mine shifts lightning fast now Gus If they are face plated like that...IIRC...they won't stay in gear on decel. That's why I just slick shift them and the syncros and put them back together. They shift flawlessly and I don't have to hold it in gear. I drove mine on the street like that for about 5 years and it doesn't come out of gear. I got pretty good at down shifting it even with a Long V-gate. I have an H-pattern Hurst Comp Plus that I never got the chance to try as I installed a street HEMI box last time it was out. The Faceplate puts any slick or Pro-shift 833 I have ever driven to shame. The dogs are finished on a slight angle to keep them engaged. Gus

Just curious....... if you had the Richmond trans in the car already...... why did you go back to the 833?

Just curious....... if you had the Richmond trans in the car already...... why did you go back to the 833? I put the Doug Nash in the car 30 years ago (1988) and it still has it. I have no intention of putting a four speed in the car, but I might switch to a different transmission if I can't get the Doug Nash to shift properly. The original four speed with the big long shifter is tucked away in the shop. I'll never use it but I don't think I'll sell it although there probably is some poor guy somewhere trying to restore a '65 Coronet who would love to have it.

Sorry..... my highjack got a bit off track. I was referring to Gus, and it sounded like he had the Richmond in his car, but took it out.

Just curious....... if you had the Richmond trans in the car already...... why did you go back to the 833? When I first put the Faceplate trans in the car I was racing every other weekend and putting over 100 passes a year on the car and two years ago I didn't even make it to the track once. I put some street miles on it now so last year I changed it out to a more driver friendly easy to shift cruiser box. The faceplate deal needs to be shifted fast or slow and I wanted to just drive it easy. So over the years I accumulated a very nice set of gears and syncros and put a box together that shifts like butter. Sorry for the hi-jack Andy If the fluid change doesn't fix your issue just call me and we can get you fixed up right. Gus

Also, if you have a chance can you post a few picture of the tunnel and trans cross member. I'm curious how much room you had to make compared to my gf5r. I'd be interested to see if you like my Long H-pattern over the shifter you are using. They are same-same from the DN for the GF.
Thanks for sharing Andy!
Here are a couple pictures of my existing transmission mount. It is a home built part from back in the 80's when I did this conversion. I didn't have very good fab skills then so it is a solid mount. I'm redoing this crossmember now so I can use a real transmission mount and hopefully cut down on some of the vibration in the car.

I'm going to spend some time over the next month or so exploring different clutch options. I can easily change the fluid in the trans too. If that doesn't fix it then maybe I'll pull the transmission out next winter and have someone get inside of it.

C'mon that's not bad at all. A little cutting, a section of tubing and you can squeeze a turbo 400 mount in there. My setup is similar except I cut a section out for the poly turbo 400 mount. I did add a section of .083 5/8 tube to strengthen it. If you make something super trick I'd buy one as it will surely be superior to my backyard junk. Thanks for sharing that Andy.

Thats why I run a vac advance, if its street driven it needs it . right now I have 24 initial, 34 total & an extra 10 on ported vac, it even makes the exhaust tone [drone] much better.
Great #'s y'all got, should be a fun car.

What Intake are you using? Any porting to the heads or intake?
Asking because we are hoping for 600+ HP from the 440 stroked to 505" 440 source kit with light weight crank, 10:1 compression (27cc dish) for junk gas, Trick Flow 240 with the solid roller springs and Ti retainers, checked, but nothing done to them. Lunati 40230732LK solid roller cam, 243/249 @ 0.050", 0.617"/0.624" lift with the 1.6:1 rockers. Planning to use an Edelbrock Victor intake and TTI headers. EFI might be in the future, but just going to run an old Holley 770 Ultra-avenger for the street, or maybe the 1,000 cfm HP Holley if we dyno it?

We did all of the dyno tests with a Holley Sniper setup. The Sniper is great to use on the dyno since I can sit in the control room and adjust the ignition timing as well as the jetting. We just hold the engine at a certain rpm and then tweak the timing and the fuel until it is working best and then move to the next point. It really is amazing what just a few degrees of timing will do at part throttle. At 2500 rpm we were able to reduce exhaust temp by 500 degrees by adding some timing. I've had cars in the past that would melt stuff under the hood while driving down the freeway and now I think I know why. Those cars had MSD billet distributors on them which didn't have any vacuum advance. We saw a big difference in exhaust gas temp between 35 degrees and 40 degrees of timing on the dyno at cruise speed. I'm tempted now to install a couple of EGT probes into my headers just to watch this in the car. I've been tuning for fuel consumption and manifold pressure at cruise but now I'm thinking I might also need to keep an eye on EGT. I observed similar issues last year at the Gratiot cruise with the motor getting warm at speed. Also running an MSD billet distributor. 24 degrees initial, 34 total. I forget what spring is in it. Ended up having to pull the inspection covers over the control arms to get a little more airflow under the hood. Never an issue with cooler weather. I've got the Holley Sniper distributor though waiting to go in. Need to finish the D60 install first.

EFI might be in the future, but just going to run an old Holley 770 Ultra-avenger for the street, or maybe the 1,000 cfm HP Holley if we dyno it? The 240 heads are out of the box with the exception of a valve spring change. I went with the Comp conical springs for this engine. I'm using a Trick Flow intake manifold that was deep port matched by Hughes. If you don't have an intake yet then that is what I recommend. Just all Hughes and ask for the deep port matched version. They cost extra and take more time but I think it is the best bang for the buck. My engine used 780 cfm of air to make 600 hp so that tells you roughly how big of a carb you need. The Holley Sniper is rated at 800 cfm and we had 98 kPa on the MAP during wide open throttle. So not much restriction.

Awesome numbers, Andy. The Coronet is going to fly and sounds like a very street friendly combination. On a side note, I wish that trick flow intake would fit under my hood.

On my Coronet, adding a bunch of timing at cruise speed dropped the fuel consumption by a bunch and the car ran smoother and cooler. No loss of power and no pinging since the extra timing drops off as soon as the manifold pressure increases. Very simple to do with a Sniper and you'll notice the benefits immediately.
Not trying to be a smart a$$ here, just trying to learn. Isn't this the same thing a vacuum advance distributor does? Or does Hyperspark distributor and/or Sniper do this with more finesse or control in some way? Thanks.

If you ever try to build a full custom timing curve in a distributor you'll know what a huge pain it is. You have to mess around with weights, slots, vacuum pods, and springs on a distributor machine. It can take hours to get it correct. With the Sniper software you just type the numbers you want into the table and you are finished. Some stuff such as high speed retard or start retard you can't do with a distributor. With the Sniper you just tell it what advance you want during cranking. If you want high speed retard you just change the numbers in the table.
