It came with the chevy 350 stroked to a 383 but I had it completely rebuilt cause the motor was old and not running right so now it has all new crank, rods, aluminum heads, medium cam, new intake manifold etc.. the guy who is building it says it will be roughly 550hp and 550 tq and I am putting a stronger built tremec t5 in it. Problem is I only have 225 sized tires on it so it will be hard to get grip but the guy who is building it said the frame should be fine but I feel like that's too much tq for the car to handle. Was wondering what you all think? I showed him that strut brace but he says it won't fit will the 350 under the hood. I can get the rear one still obviously. I won't be taking it to the track but every once in a while I can't say I won't try and punch it sometimes.
