Picked up car craft this weekend and say 500hp junkyard lq4. first dyno pull stock w exception to 4bbl intake 450hp, second pull w/ "mild" cam swap 480hp
What's up with those numbers?

 

i think i saw this, was it a kit you could build or buy or something? it was cheap as hell

 

I have this mag as well. One thing to consider is that most engine dynos still use the old std correction factors. They will dyno with 10-15% more hp than the factory std. They used a GM Hot cam and long tubes with duals as well. They are supposed to be doing L92 heads next month.

 

i thought that was with the heads.
