HP and torque are probably close.....I personally would run more timing than that, about 38 to 40 total, and 16 or 18 initial...my big blocks have always run best around there, but as always, check because every engine is different. Why arent you running vacuum advance?? On the street, it's a good thing to have, you'll be much happier with it. Jetting should be close enough to run pretty good. John
