Looking good Markus!

Fedex delivered the camshaft and I got the engine almost done already. I can drop it to the car soon and get the transmission to my engine stand for overhaul.

Image
The cam is a Melling stock replacement. So it's supposed to be a bit bigger than the stock -61 cam was. It went in nice and turned freely.

Image
This part is the most fun that a car guy get to do, the final assembly and detailing. Some paint here and there, alternator, distributor, some brackets and were done! Allthough, the serpentine tensioner needs some adjustment as the belt is interfering with water pump pulley. Tensioner is not under load in the picture but it might be too strong for this application. My first mockup tensioner was a weaker unit but it also looked like crap.

Excellent work. Should make plenty of power for that big cruiser bruiser...

Engine is back in the bay and transmission is now disassembled. Still a ton of work ahead, but I hope to get it running in few weeks!

My buddy made same cool decals for me! Planning to put one of these to the air cleaner housing. Just need to find something OE-look and cylinder shape.

Tranny had some seriously worn front clutches. Amazing that it was still working ok though. I have a Transgo TF2 kit to go with it.

Nice work, I've wanted to make some "Turbocharger 225" underhood decals for my build. :)

Little by little...

Transmission is back in the car. It took a bit longer than I expected as I got the wrong master kit for it at first. I used deep oil pan from Jeep RE42 and made filter extension from piece of steel stock. Soon I'm about to start making the exhaust pipe. I was thinking of single 2-1/2" and 2" from the Dutra Duals to collector.

Also I hide the extra gauges in the dash. I just didn't like to spoil the beautiful dash. I modified the beautiful radio delete plate to be opened with a switch and hide the smaller gauges behind it. Tachometer rises from the speaker provision in the dash. They need a bit refinement, but you get the idea...

Here's a Youtube link for the gauges: https://www.youtube.com/watch?v=jpItA_cTRaA

Wow! I love this project! I have hopes of building the same thing someday in a '70 dart. Im thinking of blocking off the backside inlet and milling new inlets for the carb on top. I want to build a sheetmetal intake to mount the m90 on its side and then build a plenum to bolt onto the new inlet so i can use a standard downdraft carburetor but still make it all fit under a flat hood.

I just have to figure out a clutch that will survive behind that kind of motor.

I have been working with the exhaust pipe, air box and some other minor things.
It was a lot tighter fit than I first thought for the 2 to 1 pipe. Primaries are 2" and they unite in 2-1/2" self made collector. Primaries end at transmission support and I welded a O2-sensor bung at the collector. I sanded down welding seams at the visible area in engine bay and put on some zinc-spray coating.

Air box welded, painted and fitted

It's a tight fit but there should be just enough clearance around. From here I continue with piping it to a filter box somewhere near the grille.

Image
Most of the hoses are done. Malpassi fuel regulator attached to the side of the supercharger

First start and cam break in is coming up soon..

Beautiful work as always!

Thanks Dan! Actually I was planning the brake upgrade couple years ago, but somehow I have managed to ignore it. However, it still is my priority number 4 :)

About ten days ago, we started the engine with my friends. It fired nice after we got fuel to the carb. Line was empty and even after filling the fuel bowl, she did not want to start at first. So my friend sucked the line and got the fuel coming to the filter. Then she started right away!

We had a textbook example how the cam should be break in. No interruptions, no gas flowing everywhere, no oli spilling. Just some venting of coolant after 20 min of break in. Total break in time was 30 minutes.

Now she starts nice, hot or cold. Although after sitting couple of days it needs a longer start.

Here she is, alive and kicking:

It needs a LOT of tuning though! Timing should be adjusted and most likely the dizzy needs some counter weight restriction. Also need to build some sort of retard system, with 5 pin HEI module or playing with the vacuum canister.
It runs nice, but slightly rich in some conditions.
One issue is that it bogs badly if gas is pressed too fast. My guess is that it needs a lot bigger squirt from the accelerator pump.
So I need to get a DCOE tuning kit too.

There's some assembly, paint stuff and air cleaner setup crafting before the road testing starts.
After that I need to get it to the dyno. Finnish traffic code requires that the aftermarket boosted vehicles needs to be dynoed if there was no supercharger from the factory. Dyno results are given to the inspector at annual inspection and he approves it, or not. Some cases like this one, it's a bit silly code as there was an optional 413 big block available and there's no way I could get near the power levels.
But dyno is a good idea anyway and we'll see how much horsepower I managed to get lost!

Ooer! I love these startup-and-run videos, and your car makes me smile. Super nice work!

When I first did my draw thru turbo slant, I used a Webber side draft carb, and had the same problem. I was never able to cure the problem, as the carb itself was not allowing a big enough pump shot. I wound up using a 500 cfm Holley 2 bbl, down draft.

i dont see exactly where in Finland you are, but there seems to be an active set of makerspaces in every major town there. they will all vary, but mine here in Canada has mills, lathes, casting equipment, etc. it cheap to access and makes all these projects much easier. try googling hacklab, makerspace, hackerspace, or whatever similar terms you have in Suomi
