Default formula 272/292 with mags speed?

formula 272 with mags speed? anyone got one, in 1990/91 they made a few with 454/365hp mags vs the stock 454/330 I know they run 60-63-4, what do the mags get it to, real numbers anyone got em?? also whats the 292 run with mags? I have been looking at 303's but seem to keep coming across really really good deals on the 272's, 292's and 311's

Lil thanks gives me a start, I've heard that the 292 was the same speed as the 272 with same power because the 272 was to tail heavy not sure if its true or not

I have an '89 292 with 454/365 with new cams, inconel valves, 850 Holleys, roller rockers and Revolution exhaust. Puts out about 420hp per. 5100rpms and she'll top out around 72-73 with 25 mirages.

I had a 1990 292 sr1 with stock 365 mags. did add stainless marine exhaust though. Ran 67 with stock exhaust and right at 70-71 with the stainless marine exhaust, pleanty of fuel and 4 adults. Also added full hydraulic stearing and that improved the handling tremendously. Boat wanted to wander with stock steering. I think I ran 25 mirages right at 5000 to 5100. Loved the boat.
