'74 Argosy engine build

I'm starting this thread to document the final assembly of my new Argosy 454 engine, running it in on my engine test stand and then the final installation into the Argosy chassis.

Here is a link to the test stand I made last winter for testing a Triumph Spitfire race engine that I built for my wife's race car. The video shows the first start of the engine where I ran it for 20 minutes to break in the flat tappet cam.

Spitfire test run

I'm now modifying the test stand to mount the 454. Once mounted I'll get it running and perform the initial break-in of the tappets. Yeah I know, lots of ZDDP! I usually use Brad Penn break-in oil and have been very pleased with the results.

I'll add more as progress is made.

Brad

Thumbs up Great setup!

That is really nice work Brad! It's so good I can even forgive you and your wife for racing Spitfires, instead of big Triumphs! Anyway the
D production/D modified cars were completely outclassed when the 240Z's showed up.
Sadly the original Standard Triumph factory where all the TR2 line through the TR6 line were built is just a lumpy, desolate, Coventry parking lot now. The industrial area is quiet. I'm not sure if the Spitfires and TR7s came off the line in that factory,they might have, I just do not know. I do know that just up the street my great uncle Bertie's "Coventry Hood and Sidecar" factory is just an empty red brick warehouse now. Every convertible top ever put on an English car, since 1920, and most European models came out of that factory. Only my cousin Dave still lives there, ain't progress wonderful ?
Looking forward to seeing what you do with that 454!
Oh Well. All the best, Cheers! Drink a pint to the memory! Rich.

What can I say, a 1963 Triumph Spitfire was my first british sports car I've owned Spitfires, TR6s, 1949 2000 Roadster, 53 Mayflower and currently drive a 64 TR4. The TR4 is by far the best performing of the bunch.

It is not appealing to me to go to all the effort of installing the engine in the Argosy chassis and then possibly finding out the engine has issues. Of course I could be jinxing myself because the only time I test ran one of the race engines before installing it was also the only time I had a severe oil leak at the front of the oil pan. I had to pull the oil pan to fix the problem. No fun when the engine is in the chassis but relatively easy on the test stand.

I didn't build this engine and while I have no reason to think it might have problems I just feel better knowing that once it's in the chassis it won't have to come back out.

Well, if you ever decide that you want to spend more time driving than wrenching: bought my wife's Miata (I know, it's a blatant knockoff of a triumph) new 12 years ago. One glitch since then when the theft deterrent system went haywire. Otherwise it has just been drive, change oil, repeat.

Yep, the Miata is a fun car to drive and doesn't have the Lucas wiring issues. British cars have always been fun to drive until they don't.

Twin SU carbs! Ahhhh the memories. I put a pair of those on a Mini 850 I once had 45 years ago, and man did it go!

And so will your moho with a "new" 454! Just curious if you can share with us what the rebuild cost wound up being?

My wife got to take a trip with a friend of ours and once she got back getting a Miata was high on her list. She ended up getting a 2001 and she seems to enjoy the heck out of it. Me, I'm sticking with my 64 TR4

The rebuild cost for the Spitfire race motor? Or the rebuild of the 454? The race motor you don't want to know The 454 I haven't stopped spending yet but I'll probably provide a list of what I spent on it.

I've been digging through all of the boxes of parts and found that I have a choice between a cast iron thermostat housing and an aluminum housing. I think I'm going to use the cast iron housing shown on the left.

The other fun part has been sorting through all of the brackets that I've collected to try and get the right combination for mounting the A/C pump, PS pump and the alternator. Fortunately I don't have to worry about any smog pumps

Nice test stand Brad!
Home built?

I had the chance to go up to Willow Springs Raceway last month, and the Spitfire were kicking butt! Stood chatting to the guy who was owning in Group 5 in his Spitfire in qualifying. He stormed away in the final, before something broke in the rear end, and he DNF'd.

Here is a video of that race for your fun!

Thanks!

I built it last winter at the same time I was totally rebuilding my wife's Spitfire race car. I never liked the idea of installing a new motor without knowing if it had problems or not. I built the test stand with the idea of being able to make various mounting plates for different motors. I'm in the process right now of fabricating 454 mounting plates.

What people are doing with Spitfire race engines is both amazing and scary. The fast guys turn the motors at 10,000+ rpm. We ran the motor I built last winter up to 8,000 rpm and it sounded great. It wasn't until she hit the track at Road Atlanta that we realized I had the timing one tooth off. It revved to 8,000 just fine unfortunately it takes forever to get there when under load

We only raced once last year so I still haven't fixed it and the odds are the car will be sold once I do get it fixed.

Here are two links of video from her in-car camera during the all Triumph feature race. If you watch closely you'll see that she almost never gets out of 3rd gear because it was taking so long to accelerate. It had tons of power (110 hp at 8,000 rpm...factory was 46 hp) just didn't accelerate worth a d*mm.

Finally got back to working on the test stand. Last night I started fabrication of the main support for the engine motor mounts. The uprights are just tack welded to the support beam for the moment. I need to fab a couple of gusset plates to help keep the uprights from spreading outwards under the weight of the 454.

I'm debating whether to install the existing 7-blade fan or leave the fan off and just use an electric fan in front of the radiator to keep it cool during testing. If I include the mechanical fan then I might be running into a space issue on the test stand. I guess once I get the engine block sitting on the stand I'll know more as to whether I have room or not for the mechanical fan.

With luck I'll have the block sitting on the test stand by the end of this coming weekend.

Stay tuned...

Brad

Got a few more things done on the test stand yesterday and today.

The radiator is sitting pretty much where it needs to be, all I need to do now is fabricate a couple of mounts for it to sit on and add a couple of diagonal braces to keep it in place. Once the radiator mounts are complete I'll start attaching all of the ancillary equipment like the starter, carburetor, etc.

I also need to fabricate a shield for the back of the motor that covers the flex plate. Last thing I want to do is get wrapped up in that thing

Did you add a support to the back end of the engine? Maybe you tied into that flex plate shield but it's not obvious from the pics. Seems like the engine mounts alone wouldn't support the offset weight of the engine and the legs you've welded in aren't gusseted. I’m just curious as to how that’s going to work. I know that normally the transmission mount supports the back end of the engine and the front engine mount is simply a landing pad that helps control rotational movement from torque effect.
