lift, not that it make a differnece, but take the lift at the cam lobe and multiply it by 1.72, then there's the lift at the valve.
Im running a carbed set up, and my durration at 50 is 245 intake and 255 exhaust with 595 lift in and 615 ex lift with 1.6's but 347 and 302 is apples to oranges. That isnt a wild cam and shouldnt be the problem. at least not as dramatic a power loss as your saying........ Maybe the car is running lean, you did say it was running hot. You gace it more air, but it might be lacking fuel
