Re: Need help calculating basic cr
You need the dome volume to calculate the compression. If your box doesn't show this on the outside panel, look at the white page inside (build sheet) and see if it is there. If not, you will likely have to contact JE because the part number that you have provided is NOT listed on their website now, so it may be discontinued or replaced with an updated part number.

Further investigation shows that you have a SRP part number and not a JE part number... these are definitely discontinued. Summit Racing still shows them on their website and state that their compression ratio is approximately 9.0:1.
