Hello Everyone! This is my first Corvette and my first car that has had aftermarket work. I have had many many cars but I have been a keep it stock guy.

Please take a look at my Garage pictures on this site and let me know your best guess on HP and Torque: I'm still a few days away from getting the car, it's on the west coast heading this way. I'm thinking 375 to 400 hp and tq around the 350/lbs???

Here is what I know or sure: 1975 CHEVROLET CORVETTE COUPE 350 UPGRADED TO A 383cu STROKER, MILD CAM, ALUM INTAKE, NEW CARB HEADERS AND EXHAUST,MSD IGNITION, POLISHED INTAKE AND VALVE COVERS, NEW WHEELS AND TIRES, 82' STYLE SPOILER, ORIG INTERIOR SHOWS NICE, PAINT IS A FEW YEARS OLD AND SHOWS VERY WELL, DRIVES AND RUNS GREAT, ALL LIGHTS WORK AS THEY SHOULD.

Thanks

Why guess? When you get the car, find a shop with a dynometer and see what you get.

Honestly, there are just too many vagaries in the description to make an educated guess worth anything, not to mention running a decent DesktopDyno (or better) sim. At a minimum "we" really need to know what cam, what heads, what carb, what intake, what headers...

Should you opt to do a real dyno pull, I'd shop for someone who knows how to calibrate and correct their equipment, or the numbers still won't mean anything.

...and, before you stomp on it very much I'd suggest to do a compression check and leak down, just to make sure it's healthy.
