CAN HEads off a stock 454 engine give a stock 305 engine horse power and around how much?
Heads off a 454 engine will not fit a 305 engine A 454 is a big block and a 305 is a small block. Even if they did fit it would probably run poorly due to low compression because the combustion chambers on the the 454 heads are larger than the ones on the 305 heads
What is the recommended octane rating for a 1970 Chevrolet Chevelle?
The 1970 Chevy Chevelle came with a 6 cylinder, all the way up to a 454 V8. If you have the 396 or 454 you need to use Premium Fuel. All other engines can run on Regular.
What is better Chevy 427 or Chevy 454 engine?
Depends on what you are doing with it. If higher rpms are a requirement, then the 427, would be your motor. Road racing would be an example of needed higher rpms. The 454 wont rev as high, however, makes much more torque. Drag racing, towing, off road, ect. From the factory, if you compare the two top contenders from each, the ZL1, 427, verses the LS-7, 454, they both made about the same power. I would have to mention that the 454 is making the same power, at a lower rpm. Some would say it is not working as hard, being larger, thus being easier on the motor. But, the arc of the horsepower curve is at its best when rpms are higher, which the 427 is more capable of. The 454 would have the edge, when it comes to stroking a mountain motor out of it. But, there were not many 427's made. Though I love the 427, I would go with the 454, personally. More power, with less effort, means less money. Also, 454 parts are everywhere. 427 stuff interchanges a little bit with 396 stuff, but, not at all with 454, so the parts are harder to find, and more expensive. Also, to make the 427 run, you need the bigger heads. Closed chamber, rectangular port. Try to find a set of those. The 454 will run good with the smaller, open chamber, oval port.
Can you run a 454 Chevy motor without a oil cooler?
Yes, if it is not installed in a vehicle that is used for towing or in an extremely hot climate.
Do old 1972 454 heads need to be redone to run unleaded gas?
Your 1972 454 does not have sodium filled stainless steel valves with rotators as far as I know, so it would be unwise to run unleaded fuel. I would add a lead additive. Do so more research to make sure I am correct, but I am 98% sure I am.
How many races did the 454 Chevy Chevelle win in Nascar?
My guess would be none. Typically, Chevelles would run the 396 in NASCAR competition while full size cars (like the Impala) would run the larger big blocks (like the 427.)
What is the range of oil pressure an a 1989 Corvette?
well it depends on the motor but any thing under 30 is not good if you have a 454 in it it could run up to 50 to 70
What is the normal running temperature for a 454 big block Chevy?

The talking heads?
Why does my van run badly after running out of deiasel?
Air trapped in lines.System has to be 'bled',that is,the air has to be purged from the lines.This is done by loosening the bolts at the injector heads,with motor running.
What is the ignition timing for a Chevy 396 big block?
Depends upon the year, and which 396 it is, but, 4, to 8 degrees advanced, or BTDC, should make it run best.
