The most common reason would be a ruptured oil cooler in the radiator. Check to see if you have oil lines going to the radiator, if you do, you need a radiator. Also, don't forget to change the anti-freeze because it will be contaminated. Don't forget to check your transmission for contamination also, as Transmission Fluid also runs on the outer region of your radiator to cool the transmission fluid.
You could have a cracked engine block.
Ya killed your head gasket dude. DONT TRY AND RUN IT WITH THAT PROBLEM. GET TO A MECHANIC OR FIX IT YOURSELF.
Yeah, but, I would use the Chevy trans, as well. You will have to fabricate everything.
If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown. If it is transmission fluid in your antifreeze, then the radiator is leaking from the transmission cooler ----- although usually that would cause antifreeze to be in your transmission fluid.
Cracked injector cups.
yes, they use the same block design and block mounting though those years. you would just need motor mounts for a 97 as thickness and offset differ slightly.
Yes, but I would use the C6 tranny too.
YES. That would be a direct swop.
A 1977 Chevy pickup truck would have rotors in front and drums in the rear
yes it will fit
Check for a fuse in fuse block marked gauges.
Low fuel pressure, stoped up fuel filter.
It would bolt in, however, that entire vehicle is run by computer, and would not even start, without completely rewiring it, even if you could get by the smog laws you would be breaking by doing this.
That would be the 700R4
YES, That would be a direct swop.
I usually change it when I do the oil. But it would depend on how much you drive and how you drive. If its no longer green/orange probably time to change it. The cleaner you keep it the better the run.
The 454 it would have better acceleration
There are no block heaters on gasoline trucks. Dielsel trucks have them on the bottom of the engine block so that heat rises. And if there is one installed on the truck there would be an outlet cord in the grill of the truck.
It could, but why would you want to? From 87 onwards, Chevrolet went to Throttle Body Injection (TBI), which was a far superior system to carburetion. IMO, you'd be better off to drop in a TBI big block (the 400 was a small block, and ceased production in 1980, long before TBI became a thing).
That would be a small block.
I would say the 2001 would win if it was 5.7 vs 5.3 because the newer 5.3 i believe has more horsepower. but it would depend on gearing.
Best bet would be to pick up a factory service manual or one of the aftermarket manuals such as Chilton's, Motor's, or Haynes.
You would have to do a lot of modifying on the body mounts. and a whole lot of other things.
yes you can but you would need to mod. the block.
