That Combo is very similar in headflow, compression, cam timing and displacement to the 427" smallblock Windsor in my Cobra Replica, IIRC it made 511HP at ~5300 and ~515lb/ft at 4400 on the dyno.

I suspect you should be in that range, it will have great wall to wall torque and feel very much like a warmed over 440 Big block but with better top end punch. I like it and the 800 AVS is a great carb...you may want to quicken the main transition with a stiffer step-up spring if it's anything like mine.

You have a little less cam and compresion so I'm gonna guess about 477hp 485 lb/ft.

460 hp at 5300 rpm,480 lbs-ft at 3900. Does that intake have a water heated plenum?



This was my first thought but since you took it I will say 465/485.



and that was my first guess so I'll say 460hp 480 tq. low compression and small cam.

I'm going to assume that it's a conservative dyno and will say 440 hp and 450 ft/lbs.

What's the current exchange rate between American HP and Canadian HP?

PS...Hope you took my advise on the stiffer step-up springs to bring the mains in quicker....on AVS's that's the key to getting them to make torque in the middle and give it a running start at HP up top!! Well tuned at WOT they give up very little at all to a Holley up to their comparable CFM rating.
