It has run really well with the 305 until it spun a main bearing causing me to put in a 350.
The 350 is nice, but still has the tendency to run a little hot. Approximately around 240 degrees.
The electric fan only works when air conditioner is on so I have to go all the time with the air conditioning on.
The starter is close to going out.
The pinion bearings in the rear end were replaced at about 100,000 because of howling noise in the rear differential.
I am almost 19 years old and this car is a great one for someone with a relativley low budget who wants a car that looks great.
The T-tops have the original weather stripping and they don't leak at all!
I was beat by a couple of foreign cars with the 305, but only beat by a Toyota Supra with the 350.
I am 5'4" and the rear seats are cramped and if going on long trips the front seats start feeling a little cramped on the left leg. Other owners might know what I am talking about.
As for your problem with overheating there are a few options. YOu can go with the cheapest, but not always the best method which is to run the fan wires direct to an ignition/battery source so that as soon as the key is on the fan is on. You can upgrade to the dual fan kit from a 350 TPI camaro. I would put a 180 degree themostat which cost like 8 dollars and get the hypertech fan switch/sensor which goes in the block. Get the one that turns the fan on at 200 degrees and shuts off at 180 and it will be perfect. The switch/sensor is like 50 bucks and takes like 20 minutes to put in.
