Not a very exciting month, I have unbuilt kits of te ones I like in my stash already...several of them.

The KTA 19 is a huge engine as it's both long and tall, 19 litres displacement and up to 600 hp. And as Steve say, it's not that easy to get it to fit in the White-Freightliner kit.

Yes you will see an increase in price, the import tariffs falls on the importer/retailer who have to pay the tariff on their prices from the manufacturer in China or from whatever country they get the stuff from that Trump has put tariffs on, and the importer/retailer will forward their increased cost to the end customer who have to pay more for the product...that's how it works.

Just type in White Freightliner WFA or Freightliner FLA on google or any other search engine and you will get lots of pictures. The engine in the White-Freightliner kits is a Cummins NHC 250, a naturally aspirated Cummins 855 cui engine, transmission is a Fuller Roadranger. Here you can find some of the information you need on the engine, this is not exactly the same but it's a Cummins 855 cui engine and most of it is pretty much the same except for the turbo and aftercooler wich the NHC 250 doesn't have. https://public.fotki.com/modeltrucks25thscale/model_magazine_articles/car_modeller/cm05_jan_1991_cummi/ Here is a typical brake system. https://public.fotki.com/modeltrucks25thscale/model_magazine_articles/car_modeller/cm03_sept_1990_truc/ The White Freightliner has wedge brakes tho' and they are slightly different than the more modern S-cam brakes. Here is a search on this forum on brake systems and you can learn a bit there. Browse around on the modeltrucks25 fotki albums and you will get lots of information there, lots of instructions and other useful information. https://public.fotki.com/modeltrucks25thscale/ And of course on this forum where there are lots of information.

The bank angle is important to get the engine to run good without inbalance and even firing, the most common is 90 degrees for V8's and 60 and 180 degrees for V6 and V12. For the V10's the optimal bank angle is 72 degrees for an even firing engine but there are 90 degree V10's like the Dodge V10 and I don't know how they solved the even firing problem with a 90 degree bank angle. Caterpillar cheated when they did the diesel 3408 and had a split journal crank where the big end of the rod pairs are not in line with eachother on the same crank pin and that way fooling the engine wich is 60 degree bank angle to believe it's a 90 degree engine and get even firing that way.

Nice work. These builds up to pretty nice models but they are by no means correct for what they are supposed to be as the chassis is all wrong for a Mopar NASCAR car.

No they didn't run that fast back then, I believe the 1/4 mile speed noted as the fastest were by Dom Lagana in 2017 at 338.35 mph and the second fastest was Tony Schumacher 337.58 mph back in 2005 wich was the National Record as I don't believe Dom Laganas was. This according to Draglist. But Brittany Force is not fastest in NHRA with her 341.59 mph, the fastest NHRA National speed record still belongs to Austin Prock in a Nitro Funny Car with 341.68 mph set last year at the Pomona Finals, the same speed as Bob Tasca III set in a Funny Car at the Bradenton, FL test and pro shootout sessions last year but that wasn't a NHRA sanctioned event so he did not get the record.

I have so many rims I like so I can't list them. Not much over 16 inches tho'

Yes I know how to do it, it just takes time. But I never heard the term English unit before, just standard for the inch and metric. I hope you don't think I don't appreciate your work because I really do...and the conversion bit is not a big deal, I'm used to it.

Yes the engine in the Revell Peterbilt and Kenworth snap kits are Cat 3406A engines with no water to air aftercooler, so it's lower HP engines but with the aftercooler they were available with power ratings up to 425 hp, the A model was also a pre combustion engine when it came in 1973 but the later A models was direct injection. As Ron says the most noticable difference between the A and B models are where the diesel injection pump is located on the engine as shown in the pictures, the C model wich is partly electronic also have the injection pump at the same location as the B and the final version of the 3406 the E model (there are no D model) is fully electronic and has no injection pump. The E model also has 3 rocker covers instead of 2 on the earlier A, B and C models and looks more like the later C15 that replaced the 3406, and most were air to air aftercooled, also known as intercooled, with the cooling element in front of the engine radiator.

Good work. Now I have to convert it to metric for it to make sence to me as I find fractions and decimals of inches very confusing.

Ohh I knew he had taken a brake for some reason but I did not know it was so bad.

I only did some orders with Jamie and his stuff was very nice, I did not know that it was so bad, I hope he will recover and I'll keep him and his family in my thoughts.

You blow me away with every detail Brian, top notch.

Nice work on one of Ferrari's best looking cars ever. This one and the 250 GTO are my favourites.

Nice. I'm still waiting for someone to do a decal for the fabric portions of the back seat because it's so hard to get it right otherwise as the pattern is quite complicated...I even contacted Keith Marks on it and he did some tests but nothing after that, and no other decal printers has done it as far as I know...so I'm still waiting to do all my Thunderbolt's as I have several of them.

Yes they are fastest in a straight line but they go by themselves, in competition with at least two cars the Nitro cars are both quickest and fastest in a straight line, from a standing start to a thousand feet in 3.623 s for Top Fuel and 3.793 s for Funny Car, at 338.94 mph for Top Fuel and 341.68 for Funny Car (a couple of Top Fuel dragsters even went over 300 mph at the 1/8 mile)...these are the national records, pretty quick and fast. F1 is quickest on road courses but not fastest for top speed, that goes to Indy Car on ovals

Jamie at Moluminum has a resin C15 twin turbo, if that's what you mean.

I follow Matt/Diesel Creek on youtube and I will follow this too.

Wrong post

The AMT American LaFrance fire trucks has a Detroit Diesel 8V-71 and it looks like a Fuller transmission, I have no clue what speed it is, 9-10-13... The Trumpeter kit has no engine but the transmission looks like a Allison Automatic, not that uncommon in fire trucks. Keep in mind that the engine in the Revell snap kits is a Cat 3406A, it came 1973 and was a pre-combustion engine at first but later direct injection, it was replaced with the 3406B 1987, so it's quite old. The Revell snap kit 3406A engines doesn't have a aftercooler, just a plain intake manifold so it's a lower power engine, but the A model was available up to 425 hp and they had the aftercooler wich was water-to-air like the Cummins aftercoolers. The 3406B evolved to the C model 1993 wich was partly electronic and the latest version of the 3406 is the fully electronic E model from 1998 and after that the C15 took it's place in 1999-2000, Caterpillar left the truck market in 2008 and concentrated on construction equipment, marine and diesel generators. The difference between the A and B/C models is where the diesel injection pump is located, in the middle of the drivers side of the block lengthwise for the A model and near the front cover on the same side for the B/C model and the E model has no injection pump at all as it's fully electronic and the E model has 3 valve covers and looks more like a C15 than the B/C models but they are not of the same family.

Of course. It's your model and you are free to do as you please. I just wanted to share the information and you are welcome to it as all here are...we are here to help each other. Happy building

The A-925 426 DOHC engine, the engine that never ran under it's own power.

Turned out nice.

It helps to have some knowledge on how things on a car and truck works when you work on models to get things right. The pipe going over the engine top from the turbo to the intake manifold shouldn't be there if you have an air to air intercooler/aftercooler in front of the radiator. If you are replicating a truck from the mid 90's the engine you are using is too old, it's a Cat 3406A wich came 1973 and replaced the 1693, the A model was replaced with the 3406B in 1987 wich in turn was replaced with the 3406C in 1993, after that came the 3406E wich is the final version of the 3406 up to 2007 when the C15 came, the C and E model was produced at the same time for about 5 years as the C model ended production in 1998. The major difference between a A and B/C model is where the diesel injection pump is located, about mid engine block lengthwise for the A model and up against the front cover for the B and C models. The E model has 3 valve covers like the C15, and the A/B/C models had only 2, the E model was also electronic and has no injection pump on the side of the block. I don't think the 3406B and C model are available on the aftermarket, only the A but the C15 is wich is very similar to a 3406E, so for a mid 90's truck I would have used a 3406E/C15 engine for it. But it's your truck model and of course you do as you please with it.
