This happened to me when I was almost finished with my resin cast Cooper F III. - If the plastic is thick enough - drill some corresponding holes either side and reinforce with brass - even .015 brass will give you solid reinforcement - if the body is too thin - then ... I’m thinking ... casting appears to be about .060 thick - you should be able to do this ... -

And once the manifold was drilled I scored a sheet of aluminum to Mark openings for the tray that sat on top of the Webers on this engine ... and with some more research I learned that the fuel lines entered the carbs from above and the the fuel fitting on each carb faced forward - the throttle linkage is cool - will mess with that once the carbs are painted and in place ...

In the Weber carburetor weeds ... the carbs in the engine kit are really good. And they just dare you to add some stuff ... so I’m making the manifold and figuring out the flanges and the orientation etc ... and drilling .... always drilling. ...

Why do I think that you have posted pix of a Tesla motor and transaxle ??? Am I warm ?

I removed the carb flanges from the top of the block casting - keeping the stems that connect each pair of flanges - well trying to - these will be re-arranged on a new manifold to locate the 4-in-a-row orientation of the Webers on the Fairlane engine ... the resin used for the printing is a good combination of strength and flexibility - allowing work with sanding sticks to prep the flanges for this purpose... if You are just making the kit engine - you’ll remove the connecting stems and you’ll be left with a wonderfully detailed Shelby manifold - complete with Shelby script ...

In order to make this as confusing as possible - I’m back to the small block 255 Fairlane engine conversion for the 29 ... these pix show the first mods to the MM Ford 289 engine ...

The Finecast kit has minimal bulkheads and chassis detail ... so a lot has to be made and a lot has to be changed ...

I am a fan of all of the Finecast kits . But as I’m sure you know - the Grand Prix kits were designed as curbsides . As for the Lotus 38 - I’ve been messing around with it for years - I tend to do a little work - and then it goes into hibernation - It may be possible to build this kit with the 25th scale DOHC - but only with numerous mods - massaging - and some incantations - the Finecast kit is nominally 24th scale - it’s actually a bit over-scale - about 1.5 scale inches too wide - which actually will be a blessing - I’ll drag this out of hibernation and we’ll see ...

That’s the plan. The Webers on the 289 were I think 54 mm. The Webers on the 255 were actually slightly larger but identical in scale. The restored 29 will use smaller Weber’s that are easier to maintain - those are the ones with the intakes closer together - nearly touching - ... but there is so much source material on the car as raced that you can make a race day replica - including some color photos taken in Gasoline Alley - which were rare in 1963 ...

And one last thing - research - the Henry Ford Museum has excellent photos of the 29 at Indy that month - and there are additional very good pix accessible on Rev’s online research library ... plus the already mentioned resto videos from the Museum ... the Gurney 29 restoration will probably be finished this summer - and I hope to study it down the line - but I’ve got enough research to do this up right ...also the Ferguson book on Lotus at Indy is a great source book too ...

This is a photo of the engine built - from Randy’s website ... it’s super accurate for the Fords used by Shelby - and Chapman used one in his Lotus 30 ... it’s the best starting point for my build of the 255 Fairlane engine - but with some important mods ... thing 1. The sump has to go - see the videos on the Indy Museum Gurney 29 resto - with some excellent views of the sump on the Fairlane engine ... thing 2 - the Fairlane 255 was raced in the 29 without an oil filter - no, really - read the Car & Driver article ... Thing 3 - the engine cover is different on the Fairlane engine - shaped and designed to both serve as the forward engine mounting and also routing the oil and radiator lines ... thing 4 - the engine Manifold is different - because the carbs in the 29 were in a line - front to back - like soldiers ... so when I’m done the Fairlane engine will look a lot different than the 289 - but it’s worth starting here because the engine will have accurate block features and the correct dimensions ...

The Car & Driver cover shot of the 29 engine is the best (contemporary) that I’ve seen. Buy a copy of this issue if you are playing along at home - excellent article on the engine - a 255 Fairlane based engine used for the 29 Indy project.

AMT almost certainly had access to the 29 when they did their design work for their 25th scale kit - but their engine as cast is under scale... a compromise to the scale ... but there are some features on the castings that are good. - example - the engine cover - it has the correct features and shape - it’s just too darned small ...

Clidinst lived ten minutes from the Speedway and volunteered there - he was given access To the Museum cars and he measured most if not all of the cars that he drew - I’m pretty sure he got the 29 dead to rights - all of the published measurements correspond with the drawing ...

Semi-gloss will do just fine -
Hope is eternal - the combustion engine is ... not .... the gear casing at the front of the engine is a one piece casting with an accessory drive bolted on its top half ... the drawing was traced from the Roger Taylor Vanwall 3 view profile drawings - they are really good - and they are at Least 50 years old - then ground and filed the profile on some .080 thick Evergreen - made the accessory drive from some .030 strip - and added Details and bolt holes ...

I shot these at the Barber Museum in 2016. They have what i believe is a spare team car - which was restored years ago to Gurney Lotus 29 specs - the real one is currently being restored by the Indy Museum. If you havent been to their site - check out the restoration videos - its sort of like one of our build threads - except that there's will make lots of noise when its done ...

Been thinking about the Lotus 29.. has anyone ever tried to scratchbuild one in 24th scale ? now that we have the Mad Mike Ford engines I think it is doable - I’m bound and determined to over-complicate this ... the restoration of the Gurney 29 by the Indy Museum has given us all enough info on their videos to get us into some “good trouble” . ..I’ve been convinced for some time that the 25th scale AMT kit is simply not salvageable - but maybe that’s just my scale bias ... ... the Made Mike engine to start with is the Ford 289 w Weber’s - although this is not the correct engine for the Lotus 29 - it’s a reasonable staring point ...
