Calculate your compression ratio...#16 Chevy 454 Big Block Performance Build... 

Excellent video as always Sir. Thorough and informative and easy for people to understand and comprehend.

Great video. You always explain in great detail. That = AWESOMENESS!!!!

Thank you for the detailed instructions!

Loved this video

Awesome video! This is the kind of stuff that makes education fun!

I was using a horsepower calculator that is available on the internet to check out what the horsepower output of this motor is likely to be and its telling me 601 HP @ 6315 RPM. The same website also calculates static and dynamic compression ratios which are needed to predict the horsepower. When I input the numbers from your video they did calculate static compression as 10.16:1 and dynamic compression of 8.14:1. The only spec the web page required that I did not see in your videos was the Intake Valve Close (IVC)@.050. I could not find this at Comp Cams website either. I used 50 degrees since Comp Cams does say the IVC is 66 degrees @ .015. It will be exciting to see if the motor meets or exceeds the calculated output. I'm going to guess that it will if you use good gas and can advance the timing to 36 degrees total advance at WOT. I guess you are going to have to find a good car to put that motor into? Hope you are having fun doing this project and making these videos for us. I know I'm enjoying watching them.

Great info. Thank you.

I’m doing a 454 build with a similar compression ratio what octane gas are you planning on using? Great video btw
