with an X1, through cats and muffler, nice!!! I'll probably be putting YT's and EWP on my 382 soon. hope to pull some similar numbers.
I'm at 457/448 now.

 

Nice numbers but you have 30RWHP in a cam change no problem

A 240/240 112LSA will idle similarly to that X1 and give a lot more power

Cheers,
Chris

 

You will not see any gain with the Yella Terras or the waterpump, I have both dynoed both and no gain whatsoever!

 

Mike, that's really nice. I've got a 383 building right now and the build sheet is very similar to yours. The only difference is CR, yours is 11.7 and mine is 9.7 (boost next year, the good Lord be willin' and the creek don't rise!). So your dyno numbers were a welcome sight as I was hoping for about 450. I do have a set of HS rockers though. Good luck at the track!
