Street Mustang out

The yellow / black scalextric Mustang is out. But maybe it should be 'A yellow / black Scalextric Mustang is out - not the one Scalextric described and we all expected though...

On all the advertisement pictures the Mustang is a 1969 (easily recognizable with different grill and the four lamps at the front). Strangely enough and without warning Scalextric has choosen to make the 1970 Mustang instead. Another issue is that the 'paint scheme' is a significantly different one from the one seen on pictures. Basically the only thing that the slotcar has in common with the pictures is that it is a black and yellow street mustang. It is surpirzing considering that none of these changes are needed because Scalextric has the right car model (1969) available AND the paint scheme that was advertised is hardly more difficult to make then the one they actually made.

The '69 Boss 302 Mustang did not have the fake vents near the roof pillar like the '69 Mach 1, fast back and base model did. The Scalextric '69 Boss 302 was correct in keeping it smooth. Where Scalextric messed up was the gas filler

The production Boss 302 Mustang for both years used the same gas filler location as the production Mustangs of those two years. The race cars did not. The fuel filler location in the factory cars is dead center between the tail lights and that location isn't a straight shot into the tank like race cars need for fast refueling. On the race cars the filler is located in one of three locations, the left side quarter panel, the center of the top of the trunk lid (rear bonnet?) or the center of the rear of the trunk lid. In all these cases the filler is higher than stock so the fuel has a straight shot into the tank. The tank doubles as the floor of the trunk and on production models the fuel fill line is in the way.

The gentleman responsible for the minor styling changes of the Boss Mustangs was Larry Shinoda. I met him once a long time ago, a rather nice quiet gentleman.

I first learned to work on cars with a neighbors '70 Boss 302 in the mid '70s. In the early '80s I owned a '70 Mach 1, 351C 4V, toploader 4 spd and 4:56 gears. About the same time one of my friends bought a '69 Mach 1 which we gutted and set up for a 427 HR. I think he's got a 351W in it now with a 429 SCJ waiting for me to drop in. I had my car crushed when I was done with it
When I'm done with a car it's done for good. My neighbor sold the Boss 302 and the guy that bought it wrapped it around a tree a week later. I guess he didn't believe me when I said we'd stepped up the motor a bit

Both the Boss 302 and the Boss 429 Mustangs get a lot of press. I personally feel that both cars were pigs on the street. Even on the track they weren't much but they allowed the race teams to run heavily modified versions legally. The race cars and the street cars shared the same body and some other parts but there was no comparison in tuning and set up. The 302 had no bottom end power until about 3K rpm and the 429 had no top end power due to hood clearance problems. Both cars command top dollar today but that's only because collectors want them, no other reason. You can easily duplicate these cars so you have to watch out for reproductions being sold as the real deal. I've seen dozens of these reproductions being advertised as real cars, very sad. Even worse is that many people don't know what to look for and actually buy these things whish are converted 6 bangers or rebadged with the proper VIN.

I've always liked the looks of the '69 and '70 Mustangs but that was all, just the looks
I think I owned mine for about five years.

There were two different gas caps on the street models that I can remember. One was a twist on and the other was a quick release. I really can't remember which one was on the Boss cars. I had the quick release on the Mach 1 but it was an option for the other cars too, I'm sure. I didn't remember the horse so I climbed up in the attic and sure enough, there is a horse on the thing
Good catch.

Although I had my car crushed I had gutted it first

I have to agree with that Fergy. I've built both a '70 Boss 302 and a '69 Z28 Camaro with the infamous DZ code. The real cars, not the toys
They weren't a whole lot of fun for commuting but when the road got a little twisty and you could open them up, things got fun real fast. We limited the Boss to a 6500 rpm shift point since it was driven often but the Z car was a tad bit more powerful since it didn't go out much. Can you say 8500 rpm shift points? It still pulled at higher rpms but I prefer to remain conservative so the rev limiter was set at 9K

OK, so neither engine was perfectly stock when we got done with them but they were close to stock?
Since then the Boss was utterly destroyed and the Z car is supposed to still exist but it's kept under wraps. Apparently the value soared when I wasn't looking.

You still see the occasional Boss 429 car running around here. It's kind of rare but they are here. I can probably see three or four a year if I bother to look. I stand by my earlier comments pertaining to the 429 car, it was a pig. It managed maybe 14s in the quarter and don't even think about road racing that thing. The one you want to watch for is the Boss 351 car. It looked like a boat but it ran like a scalded dog. I've never worked on one of those but they are here too.

Yes, the motor was fully balanced and blueprinted using not exactly stock components
Lightweight pistons, forged crank, solid lifter cam, GM off road racing heads (fully ported and polished with stainless valves, lightweight retainers and double valve springs) fully ported intake specifically made for the heads, half inch diameter fuel line, etc etc etc.

The 302 (4.9L) was considered a tiny engine up until a few years ago so it has no reason not to rev. The racing versions run up around 10K rpm. The guy I race toy cars with has an old '71 Ford Torino with a 429SCJ. That motor is mostly stock and is shifted at 7200 rpm. It does high 11s NA and 11.20 on the bottle.

215ci alloy V8 based on the 50s Buick motor.

I've never used that motor because it's too difficult to get here. Where I am it's a whole lot cheaper to just use a small block Chevy and call it a day. My current daily driver uses an alloy DOHC V8 (4.6L Ford) and with it's automatic transmission the factory shift point is 6200 rpm.

If anyone ever tells you American engines won't rev, they don't know what their talking about. We can make anything rev up but why bother if the engine can make 950 hp @ 5200 rpm?
