Lunati Cam

Tighten it up too .020/.022 or .022/.024

See if it makes any difference.

Thanks. We're going to do that and the Air Gap/Carb change to see how much of a difference that makes.

That cam won't pull to 7200 rpm in your 414 like the specifications say so don't expect that. They really shouldn't spec rpm ranges with cams cause engine size (along with induction flow) makes a huge difference in the range it'll work. My guess is it'd work just fine with the air gap cause it'll make peak HP around 6000-6200. On paper it looks to be a really aggressive cam so it should make good power. I haven't ran the 528 cam you have so I can't say how much difference their would be.

Wouldn't expect to rev it to 7200 rpm, the current 528 is limited to 6100 rpm as its all over by then. Peak power from memory was at 5200-5500.
It falls over at the deep end on the 1/4 the 1/8 is just fine as it cuts a 7.65 which should be high 11s. On the 1/4 I can't get it under 12.3 with mph of 112.2
