We had a guy bring in 454 engine to put in his 69 Corvette.
I dont care for corvettes much, but the 454 in it, it could give you hard on just listening to it.
I had the "baby brother" of the 454 in my 1972 El Camino (built 8/71): it was the ill-fated 402 CID. It could pass anything but a gas station (4 MPG in town, 9-11 MPG hiway). The first week after I got the car (truck?) I had to take it back to Chevy for warranty work: it tracked all over the road. Turned out: the front end was made wrong, the frame holes for the lower control arm on the right side were over 1/2" out of position. They just jammed the adjustments all the way to one side to make it steer straight-ish and gave it back to me, telling me "that's the best we can do". Uh-huh...brand new GM car.
I drove it down to college (170 miles away) the next week, stopping for gas at the 100-mile mark because it was EMPTY. Turns out, it had a little 16-gallon tank (17 really, but the last gallon is below the fuel outlet's hole) with a monster-thirsty engine. Uh-huh. Needs premium gas, too, or it pings like there's something loose inside the cylinders.
Then I took it to a local old guy in Macomb (at college - grey hair counts, to me...) who "knows Chevies" and he removed the right lower control arm, welded the subframe crossmember shut with a couple of hand-made metal discs, and bored the mount holes in the RIGHT position, so he could align the front end correctly. Not warranty: had to pay [a lot in 1971 $$] to get this fixed. Then we notice: the right front wheel is bent - these were the semi-custom 5-spoke GM 'mags' of the day, color-matched to your car, quite the expensive option. So, call the dealer back: they will order a wheel. The next month it comes, and I go to Chicago to get it: not painted. OK, they will paint it today, come for it tomorrow. Next day I get it: does not match the other 3, nor the car, at least 2 shades lighter. Have to take it, school on Monday looms. No, they won't do it over. I've had this car now 50 days. Uh-huh.
In November (car is 3 months old), puddles of oil appear under the engine, and the clutch slips. It has 6000 miles on it, now. Dealer says, "warranty is 90 days or 3,000 miles", so I have to appeal to the Chicago dealer. I do, local dealer tells me the engine must come out for a new rear main seal. They pull the engine the next week as I ride my 750 through the snowstorms to get to work: well, they don't have this type of seal, have to order it - from Detroit. Uh-huh.
Three weeks later, my car and engine are still in the same stall at this local dealership. They can't get the seal, they say. I mention this to the above-mentioned "old guy who knows Chevies" and he comes across town to the dealer, walks into their part department, and picks a seal off the shelf, walks it out to the Service Manager and tells him it will fit my engine. (Side note: I also work on the "old guy's" CB750 for him from time to time...). The Service Manager has that deer-in-the-headlights look, takes it to the engine where we all look at it and, gee...it's the right one. Uh-huh.
A week later I get the car back, head to Peoria to get some 750 parts there. About 80 miles enroute, all the belts fly off the engine, at 11 PM in a tiny farming town. A kindly person from the house on the road where I am stopped offers that he can call the gas station (only one in town) owner and he will come out (really?), and he does (!) at midnight. This teaches me a lesson in "customer service" that I have NEVER forgotten since...he installs all new belts for me in 30 minutes, charges me for the belts and $10 - I give him $20. On the return trip to Macomb, all the belts fly off as I pull into town: total belt life was 125 miles before something destroyed them. Uh-huh.
Next day, I get all new belts and install myself. Something does not look right for the power steering belt, but I have to go to Missouri the next day. Take extra belts and tools, hit the road, hauling a CB350 in the back (to my brother). Get 85 miles out, one belt lets go and WHAPS the inside of the hood, so I stop: it is the one on the A/C pump, so I lose my cold-air defroster for the trip. Can live with that. Get to my destination (350 miles) and open the hood: the power steering belt is frayed like it has 100,000 miles on it. Uh-huh.
Pull off the power steering pump: the morons at the dealership had installed the mount bolts in each other's holes during engine reinstallation, then stripped the bracket with their cross-torque force. Have to remove the bracket, make new bolts, drill out the threads and use nuts instead. The car now has 8,000 miles on it. The misaligned, flapping power steering belt was hitting the other belts, causing the problems. Had to fix it myself. Uh-huh.
In December and January I have to drive to Chicago 6 times, and Missouri once. By February it has 12,000 miles on it. I drive to the campus one late February day, then find I cannot get the shifter into Reverse: and, you cannot get the key out of the Ignition until you shift to Reverse. Lock up with my spare key and a towel over the still-inserted one, go to a garage in town to get up on a lift, and pull out the shifter: the reverse pusher-spring cylinder is completely rusted tight, happened between Friday and Monday. I remove 2/3 of the spring inside and reinstall the switch housing so as to still have backup lights, filling it with grease against future water: there is NO SEAL of any kind on this switch, under the car. Uh-huh.
Three days later (March 1), I chase after someone at a stoplight drag and when hitting 3rd gear, the knob (tee handle) breaks off the shifter. Bust my knuckles into the plastic dashboard, which also cracks across its face, clear to the glovebox. Uh-huh.
I get a new shift lever (only $108 in 1972 $$) and install it, and park the thing in front of my house with a For Sale sign in the window. It has 13,000 miles on it. I paid nearly $4000 for it, less than 8 months before. The paint if coming off the hood in 4" large chunks, the front end needs alignment (again), the clutches in the posi-trac differential are slipping (both sides), the rear main seal leaks puddles in minutes, which has ruined the clutch and pressure plate, the front main seal is leaking in a stream when it runs, the carb has caught fire numerous times (because you have to drop the clutch on it to shut it off, or it won't stop chugging), and the tires are bald. The first guy who offers me over $2000 takes it away.
I went to Iowa the next week and bought a Toyota. I've wished GMs on my enemies ever since. Now, the government owns them (despite what the Press says about it).
Uh-huh.
