If that is a Motion car it really makes me question some of the mystique and values floated around for them.

Looks like something the typical backyard guy would do with some rubber fuel line.

Not impressed.

Part of that is it was the '70's and the detail was not as big a concern as today. Also you did not have all the hi-tech billet do-dadds and plumbing back then, you had to fabricate your own. Also to be honest Motion was not known for their neatness. I saw one pic and they added traction bars and spray painted them after instalation and had overspray all over the rearend and gas tank. On the V-8 Vega 454 that Motion did they just took a sledghammer and beat back the firewall. I think a dealership car built today along those lines would have had a custom firewall built IMHO because we have higher standards.

BTW, my mustang TR had a Moroso y-block mounted on a custom stainless steel mounting bracket. Looked much better than Motions setup but I have seen worse than Motions setups in old pics.

In regards to the rubber lines that is what people ran back then. Only the top fuelers and f/c's ran stainless steel braided lines. I started to see SSBL really taking off on street cars starting in the the mid '70's.

Those were some primitive days & crude techniques.
Both at the speedshop AND Factory back then.

we have built 2 tunnel ram street cars. car 1 was a 68 firebird with a 400" chevy 10.8-1 comp with AFR heads and a comp 294S sam. 10" converter and 3.73 gears. used a weiand street ram with 2 rebuilt 450 mechanical holleys. all we did was drop the power valves lower because of a lack of vacuum because of cam. this car ran awesome and was wicked responsive even with the automatic. never got it to the track because a professional football plater saw it in front of the garage and bought it. car was an absolute blast the short time we had it.
second car was a 68 camaro with a 9-1 454 and LS-6 mechanical cam. 4-speed and 3.73 gears. same weiand street tunnel ram but 600 vacuum carbs. car was pretty mismatched but ran real good for what it was. we ended putting screws in the secondary linkage and it seemed to help but was NOT the way to do this. car looked tough and was a blast to drive. mike

The photo wasn't really meant to impress anyone Dirty, it was just shown as a reference to a TR setup---Those rubber fuel lines are industry approved gas lines that would have been used in a line splice especially were vibration and stress were a factor-----A lot of Motion photos weren't staged ie guys in white coveralls installing engines with scrubbed clean equipment--the photos were taken as the work was being done--that's what I always thought was so about those old photos of speed shops --Anyway, I'm not here to defend anyones table manners or lack of but you should be impressed by Motion and other HI-PO shops that built cars that set records and ruled the streets in a time were grease under your fingernails was just part of the job-------------

It doesn't need to look pretty to go FAST!

That was pretty much standard fare back in the 70's.I had the article of Grumpy Jenkin's 70 camaro prostocker from the 1970 issue of Hot Rod,and it mentions how the car was plumbed with"Neoprine" hose,as if this was some kind of state of the art feature at the time.The trick record holding prostock fuel system consisted of some 5/8" metal home heating tubes soldered into the top of the tank with rubber hoses running to 2 Carter fuel pumps,the same kind you could buy for $9 at the local parts store at the time,and the engine compartment fuel lines were all done with hardware store grade brass fittings and rubber hose.This was state of the art back then.This could also be why the Grumps Monza burned to the ground so fast a few years later,but the fancy fuel systems we know today wouldnt be around for years to come.

The real tuth about most supercars was way too sugar coated.Most of these highly valued supercars had sledge hammer adjustments done to fit oversized tires,and exhaust systems,and you have to remember that these super valueable Motion supercars were about as pleasant to drive on the street every day as having a prostock race car with mufflers.That is what made them so valuable,the race car mystique.In reality,they were hard to drive tempermantal beasts that were broken down more then they were running,or at least that was the case of you actually drove yours the way they were intended to be driven.Most of them were either found burned alongside the road because their owners grew tired of their beastly ways,or were converted to full on race cars and evolved off the streets.Thats just how it was.The fact was that the Motion car wasnt anything that the average kid couldnt have built for half the price at the time in his back yard with hand tools.In reality, even the winningest of prostock cars from that era would be nothing more then a bunch of cobbled together parts that wouldnt pass saftey inspection at even the most backwoods track in rebel country today.Back then,they were record hold state of the art race cars.

Hmmmmm.....very well said IMO.
