Arent you worried about 25lbs of boost? I am a bit scared to cross the 21lb line on a stock block...

Not really, considering the timing advance was VERY conservative and it was was running a mix of 91 pump and VP Racing 100 octane. Now 29-30psi with much more aggressive timing advance, that's when I get a bit sketchy on the stock block.

I was ALMOST tempted to see what the SZ55 would do with the dyno queen map, but I cracked open my wallet and saw that there weren't enough funds to suffice for the new built shortblock just in case something happened.

Nice numbers! What do you think you'd run the 1/4 mile in on pump gas?

I know the topend is sick. I love my SZ49 I can only imagine how the SZ55 pulls. Nice work.

how is the stock block holdin up with all that power? i thought these motors were quetionable around the 400 wheel mark? should one not worry?

what is the breaking point (wheel hp) for the stock block?

Well thats good news! I just came from the tuner and it looks like I will be running around 24 lbs now with my GT30R and FMIC, so we will see. The Tuner says that we're cool all the way up to 30 lbs. Looking to make around 420-440 Whp when we are done.

there are stock blocks on motors producing close to 600 whp out there. you can search nasioc to find them. kingpin has a few.

Definitely, just gotta find the right tuners out there

that makes all the difference. I am definitely interested in seeing how the newer blocks (late 04+) hold up to the bigger #s with their improvements.
