I'd be tempted try the voodoo marine 245 / 250 on a 112

Does Lunati make their cams?

Reason I ask is my engines were originally built with Lunati pistons. The bulider at the time swore by them. Fast forward from 2004 to 2010, I needed a piston. I had to custom order 4 from Lunati. It took 7 weeks to get them and when I opened the box, much to my surprise, they were Weisco pistons.

I feel like this thread is getting a little off topic. For marine 454's to 555's, we know the Crane 731, 741, 651 are all proven performers in a pretty wide range of combos. I have had really good luck with Lunati 20110669 234 / 244 .629 / .612 The 20110670 works awesome 238 / 248 .640 / .629 As well as the 0671 242 / 252 .640 / .629 All of those run with average spring pressures, and the smaller two I've used with stock gm lifters no issues. Any other known reliable Isky, or Howards grinds, etc. post em up. The comp XM lobes work well but don't make as much power as the lunati.

The power curve of the engine will move upward as the duration does. Sometimes not as much as I would expect, especially with good cylinder heads. There's too many variables to determine exact hp. Running all your specs through a program like pipe max can certainly help get closer. Based off of other builds I've done and seen. I'd probably go with the 238 / 248. and look for around 650 hp at 5700 ish. Of the heads flow better then I guessed, peak rpm will move up a bit. It should make around 675 torque

I'm not a cam expert, I'm just going off what I've seen work, and what hasn't. I'm always willing to listen and learn. Hopefully others will chime in with their suggestions as well.

Thanks

I believe so. They were owned by Holley, but I think are part of Comp now? It's hard to keep track, a lot of companies are merged together now, or owned by one big parent company

So are boats for that matter... Nothing like a shiny new BAFOUNZI

Lunati's cast core ?

Tim has a thread in the Cig section we should discuss more there.
