I visited AJ today to nerd out with a Motörhead. AJ built a 1955 Chevy step side pickup, and owns 2 1/2 Porsches plus mucho parts, plus a 1940 truck.
Know that his dad is a licensed drag racer with a car.
I inquired about 356 Porsches, what makes for the cult following, and what is the hype. Pretty much kinda hand built, light in weight at around 1800 pounds, and powered with about 90 HP. The round lines add a softness.
Some of my logic got validated lowering trucks or slamming them is more show than go, and lowering trucks and going low profile tires in an exaggerated manner is well overdone.
It does seem to be a limit for me as an 18 inch wheel is the smallest I can get from Detroit Steel Wheel. I mentioned being able to recycle the dog-dish hub caps. Figure $380.00 per wheel, then add in the option of a $65.00 semi-gloss white powder coat, and a $25.00 cost for drilling and clips to use my OEM dog-dish hub caps. These costs are just for one wheel, so multiply by 4.
Anyways this preserves the OEM look I want, even though I’m changing from narrow 15 inch rims to wider 18 inch.
If I did what everyone else is doing it would be a 20 inch wheel or even a 22 inch wheel with a narrow sidewall. Perhaps if I was racing or doing auto cross then there would be a practical reason.
For comfort a taller sidewall is my friend, but sticking with the 15 inch rims means a limit of smaller diameter rotors on the brakes. Not a good idea on a vehicle this big and heavy.
Know that those low profile tires and wheels add weight, sprung rotating mass, so acceleration, braking and ride quality all are effected all in a bad way. Expect more brake wear and poorer gas milage.
So the 18 inch is not an exaggerated look, and is more than the 17 inch wheel size that the Tech Ride coil over suspension is designed for. I’ll be adding some firmness to the ride, not a lot, but then the suspension is not only more advanced and better dampened, it also corrects the camber geometry for a more neutral steering for less bump steer.
I want the truck to ride and handle more like a car, so lowering the truck is part of it, then there is wheels and tires. I’ll have some cush (sidewalls), better acceleration, better braking, and higher MPG by going extreme with the low profile wheels and tires.
Still need to exceed 28 inches on the tire diameter. Right now on the truck is 255/60/15 and 215/75/15. Originally OEM on the truck was 215/75/15’s on all four wheels. The wide lower profile 255’s currently are mounted on the front. The C-10 has no power steering, so no way the wide tires belong on the front.
Had a Jeep CJ-7 with manual steering, and 235/75/15’s required upper body strength for parking, but it was something I could live with. Anything wider just has too much friction.
In the past the 255’s on the rear made sense since Chevy’s had a 2 inch rake to the stance front to back. The lower profile tire has a smaller diameter than the 215 fronts so the truck sat closer to level.
I’m 67 and the 1966 C-10 is only 8 years younger than me. Pretty sure the front sagged at least an inch, and the rear about 3-4 inches. With the shorter tires on the front, and the taller tires n the rear the stance is currently level and about 14 inches above the ground to the bottom of the body.
Don’t forget this truck was bought/built for a camper. This would explain how the 2 inch rake got taken out, plus some more.
I figure on the Checker limo the bottom of the rocker panel was about 9 inches. I know that because I could slide under the car without having the car jacked up or climbing a curb. Somehow between the wheels, tires and suspension I have to drop the truck 5 inches from its current stance.
So a lot of daydreaming, researching, and connecting the dots. It was the early 90’s when I installed a Corvette engine in an 84 Jeep Scrambler, but a lot has evolved since then. Pretty much the heavy lifting and engineering has been done.
Still not cheap, but still cheaper than buying a new truck.
The new ZZ6 is basically my old ZZ3 crates motor, but with a lighter valve spring and valve retainer that allows about 200 higher RPM’s. For my usage this really does not matter or count. I’m considering the ZZ6 that is sold turnkey with a carb because it has a flatter torque curve than the EFI engine.
Less complexity, simpler. No need for an electric fuel pump in the gas tank, no need for a return line, no need for a more advanced fuel tank. No computer. Save about $1.5K.
Of course Cancer treatment first… and that’s two years…
