you mean 741,,731 is 226,234

Yes.

For those who like this kind of stuff, I really recommend purchasing these programs, or putting them on the xmas list.

Some engines might like the tighter LSA . Is it gonna make a difference how the boat performs, between those two very similar cams, nah. Not in my opinion at least. The 114 LSA version of it, will idle a bit smoother.

Thats another topic as well . With modern EFI, or programmable ignitions with carbs, alot of the idle quality issues, can be tuned out with bigger cams. If a smooth idle is what you like, a cam with less overlap and duration will do better, as long as its tuned properly. I know that by getting away from locked timing on my blower engines, its night and day how they idle around the docks now, with the same camshaft.

I know there's a lot of what ifs. Change this and change that but I'm glad you stuck with the actual cam specs. There's a couple I'd love to see lsa changes but it is what it is and you stuck with off the shelf cams as it. That's good.

I hate to ask as questions will never end but since the 741 got it I still think numbers would increase with smaller runner as mentioned in other post like the 305 cnc but I realize you have enough time into it as is.

These software programs are interesting I only wish iPad Apple Store offered something but they don't.

Funny we were using that cam back in mid 80's prior to even having a part number. i know shops that continue to use in builds to date in anything 496-540 with success. Not wild builds but extremely reliable. Something to be said about that I guess.

I'm am pretty surprised by that, and it's great info. Thanks for doing all the leg work. I knew the 741 was a good cam, but never expected it to outdo all those. Especially with a modern cylinder head package.

the 741 and the 525 efi cam is a good choice for 3500 to 6000 rpm but imo not the cam to use if you want more hp at a higher rpm..for ff tim-either one of these would be good for reliability but not max hp.i am curious as what camshaft you will use next tim.

Great post!
