For the most part your right Luis BRW. It appears you only got part of answer.
So maybe this will. The stock compression on the 292 should be just fine for what you have in mind. I wouldn't deck the block for increasing the compression. Because any type of forced induction likes the lower compression. The higher the compression is The less PSI you can add. so the lowwer the compression is the more PSI you can add. with 5-7psi(maybe as much as 9psi) you should still be able to run the 87 oct. pump gas any more then that you wil need to increase the oct. level. I hope that this helps Or gets someone else to jump to give you the answers your looking for. Sorry we got a little side tracked.
