I've been building a 1969 Firebird with Art Morrison front and rear subframes connected by me to make a full frame under the unibody. The front has C6 corvette a arms and brakes, the rear has an Edsel style round back 9" ford with a nodular Daytona center section and posi. The rear disc brakes are 78 mark V. It will have 18" wheels 8" wide in front and 11" in back. This weekend I got the motor mounts moved in the chassis (Chevy to Pontiac) and fitted the Gear Vendors OD that Scottly fixed me up with, to the T400. Next is to assemble the powertrain and mock up the rest of the driveline so I can order a driveshaft.
A few years ago I put on the heads. Of course they are backwards. The frost plug and heater nipple are on the wrong ends. It's never been started but I assume the head gaskets are toast by now.

The bolt is in the old location, the other hole is the new location for the motor mount bolt. 1 1/4" to the pass side and 1/2" down.

Hey Don...looking good. I'm very curious how the Gear Vendors Overdrive works out for you. We currently have 3.42 gears in the firebird with TH400 and thats not conducive to highway driving.

I really like the idea of how the Gear Vendors works and would prefer to retain the TH400 but still have overdrive functionality.

Don R · « **Reply #2 on:** November 02, 2020, 08:48:20 AM »

I had the 3.50 gear, it did seem awfully buzzy at 70-80 mph. It might be a while before it's running.
I sold some of the original parts way too cheap. It's like having a bunch of 750 K0 stuff and not realizing other people need it. I learned after the fact my disc brake front end is the same as 69 Z28. Should have been worth $$$$$, was sold for $ L0L!
If I had do overs back to 1970 I'd buy a beater to drive and keep this car dry, we just wore it out. I'm sanding the pimples and flashing off the Turbo 400 today. Man, you could snag your shirt on that thing.

Hey Don....maybe i missed the history here...how long have you had this Firebird in your stable?

Don R · « **Reply #4 on:** November 02, 2020, 05:50:55 PM »

I got it used in 1970. I traded in a 65 VW Squareback, two friends claim to have owned it first, I had breakfast with them both and they can't even figure it out. I remember the one guy trading it in on a new 70 monte carlo.
Then he admitted his wife hit a fire hydrant with it, but also says he owned two that year. Jeez. All these years of him wanting it back and restored. He remembers it having AC too. Imagine how silly I felt never having turned it on.
I posted a pic on the pontiac midwest connection FB page. There's a huge discussion about transmissions 200, 5 speeds, 700R4, etc.

I realized today that the short block of the 400 motor is from a 53,000 mile 72 Catalina, so this must be the Bird that swallowed a Cat.

Love the old F-Birds, had a '68 in high school.

Subscibed...

I pulled the heads back off and turned them around to the correct sides. The cam looked rusty as heck. I think it's just the grease I coated it with years ago. I pulled it and slipped it into a pvc plastic tube with some ATF and PB Blaster to soak. The challenge will be finding the correct bolts, nuts and brackets, I had two motors apart, was putting one in the car when the $$ was too short. It's sat for years.

Don R · « **Reply #7 on:** November 08, 2020, 03:29:47 PM »

I've cleaned the cam off and re-oiled it, I'll used some proper assembly lube this go around. I'd love to build something with a crazy intake but will proceed with the minimum cost until I see if I can afford to finish the rest of it. I'll be using aftermarket AC so I'll check to see which brackets are best to work with the Sanden compressor brackets.

Hey Don, I forgot to mention that my neighbor has a 400 block, heads, and crank from a '67 Gran Prix, which would all need to be refurbished. The heads are "670" large valve parts, which he told me were somewhat prized? He would be willing to sell it all for $400 plus shipping.

That's good price, I'm trying to not buy extra although if it was close I'd be tempted. A hoarding habit runs in my family, I think it comes from our parents living through the depression and a world war. Dad used to re-box his old spark plugs in case a new one went bad. My brother picked a cb500 windjammer bracket out of my scrap pile, later he bought a 500 and asked if I have one. I said no, but you do.

Don R · « **Reply #10 on:** November 23, 2020, 07:55:55 PM »

67 would be the meaty block back before they went thin on the castings. My heads are #48's, maybe too high on compression and also have the big valves. If the comp. is an issue I'll buy better gas. IDK.
I have two sets of 304 stainless steel exhaust pipe ordered, one builder kit and one X pipe kit. Hopefully it will get the exhaust all the way out and wind around the overdrive. I'll still need to order manifold connectors and mufflers, I'm thinking 30" stainless steel rock wool glass packs. I still miss the old glass pack sound. It it's still loud I'll add two 12"ers in the 18" exhaust tips. It used to idle like a boat with a water exhaust. A buddy of mine used to follow me to the car after work to just listen to it idle.

I got the motor mounts squared away and put the engine, trans and overdrive in.

Don, did you re-fill the OD fluid? I never did find any fill plug, only the drain...

This is all just a mock up to make the exhaust and driveshaft. I did fill it, but first cleaned the sump, it just had a tiny amount of shadow dirt in it. I just poured it through the hole under the plate on top. The deep sump is for trucks and motorhomes. GV said I can remove it if I buy a $70 plate. I think it will clear the exhaust fine. I'll drain it and refill it before use. I managed to spill a bit of it before it got assembled but thought it would be best to have some in it. I could also buy a shift computer but will use a shift knob with a button on it.
I remember freshening the trans twice but can't say for sure who did it the second time. It's probably due again. Was shifting fine when the old engine let go though.

My buddy with the Hot rod body shop came by, he thinks repair to this body would cost a bit more than buying a new one. That's what I was afraid of.

I like your 69' FireBird Don

a work in Progress but I can tell you're giving it the Full Treatment

My Strange engineering front coil over shocks should have been delivered today, I won't be here most of the day tomorrow to sign for them. I've been under the car all afternoon making two rolling offset exhaust pipe fittings from 2.5" stainless steel.
The band jumped off the band saw twice so I changed it and tuned up the saw a little, it works a lot better now.
Almost a blessing in disguise.

The band saw is a very nice shop tool,the kind of thing that you don't give a 2nd thought to when you go to use it.I love when I can use one that's been maintained.

This is a green china made el cheapo drop band saw that someone gave to me nearly unused. He borrowed a great carburetor that I never got back so I'm calling it even. I stood up the top side and made an aluminum table for the saw. I considered not fixing it since I've seen the motor smoke on an average cut. This seems to be working well now so I'm glad I didn't junk it.

Don R · « **Reply #19 on:** February 26, 2021, 08:59:15 PM »

I got the front coil over shocks mounted, sat it back on the tire stands and it sits really good, I'm seeing just over an inch of tire between the fender and rim, this is with the engine trans and od unit in but no accessories, front bumper assembly glass or interior. This is with the preload adjusters fully down. I'll need a scratchproof wrench of some kind.

Don,I had a 69' GTO with a smashed-in nose for a little bit back in the 70's:400 w/ 4-speed.I remember that 'endura' rubber type bumper being Big $.. I never did get one.I traded the car for 1968 Dodge Coronet 440 R/T convertible(Oh,I wish I still had it)that was seized from snow going down the manifold (this dope who owned it left the carb off through the Winter back in Ct.!)and I didn't have the $ at the time to rebuild it because I was working for my biological Father..
The Firebird has that center grille with the chrome bumper around it.Do the outside parts that surround both sets of headlights also have that same type of urethane bumper/protection as the 69' GTO had ?

What steering rack are you using on there? I was just looking at a borgeson 800 box for our worn out one in the 73 and noticed you are up another level from that

Don R · « **Reply #22 on:** February 28, 2021, 04:04:31 PM »

This one came on the front clip it says Detroit Speed. I think Art Morrison Enterprises is connected with them business wise.

Ahh..I missed you weren't using the stock front subframe

Don R · « **Reply #24 on:** March 01, 2021, 06:14:48 PM »

Yup, full frame. c6 vette front and 57 Edsel in back! This one is a new repro 9" with the round back and no dimples. My 40 Chevy has a real Edsel rear end in it. I asked the junkyard for a 57 ford axle but when I was leaving I noticed the Ford was still there and the Edsel was moved. It worked out, the width was perfect for my rims.
