You shouldn't have any issues with idle quality and the current cam you have. The 525 efi cam would work really well with that setup and it responds very well to boost. 236/244 @.050 114 lsa. I have one coming out of a motor in the next week. Johnson lifters as well. Cam does have a flat nose for mark iv block...

Very true. Maybe he could stay NA, and just run a low pitch prop for those wakeboarding and tubing days. Then when not playing mastercrafter, he could bolt the big prop back on.

It's a Gen6 block. Would it still work?

can't help much on cam, but I ran a HP500 with a procharger for years, several carbs and EFI, last setup had to go down to a 750 from a 850 to keep from leaning out at WOT, thanks god for widebands. the air was being blown thru so quickly that would not pull fuel, the 750 worked perfectly

I like the 525 EFI cam or similar
I towed wake boarders and kids on tubes behind my 1000 hp procharged efi 272 all the time, if i was going to have a full tank of gas and 7 people in boat AND tow i would throw a 28 pitch on, i also had 24"long trim tabs but had no problem popping up on plane and staying planed out at 20 something mph around 2800 rpms with a cam that was 245/255 then a cam that was 252/259. It was a 540 but still wasnt difficult whatsoever, fwiw, smitty

Since you tow tubers and wake boarders, I'd look into selling the centrifugal, and picking up a 250 blower. Couple that to those oval ports , should make more than enough low end, and good top end as well. Throttle actuation and response down low with a roots is very good.
