Back on post #68 the old engine was "243hp/253tq"
Assuming both runs on the same dyno, congratulations on the 159 hp or 65% increase.
402 at the wheels would be somewhere over 500 hp at the flywheel. That would be quite an accomplishment with only 302-306 cid NA. It may be a true reading it may be off a bit. Don't get too wrapped up in the number and focus on the improvement when using a like for like comparison.
This important question is "given your high altitude driving, how strong does it feel to you now?" Is this enough or do you want more? You could add 25-30% more with a mild 4-5 psi boost on a future project, now that you have a good foundation to build on.
Good job!
