Default Carlos Magnum with MB454

Sorry we been busy and haven't been showing completed projects but here is some pics of a Friends magnum we built a 454 that made 585 hp and 560ft lbs of torque he's got it in a 27 Magnum sit down. We tested Friday before the regatta and turned 5500rpm at 71.9 on the gps needless to say this is his first boat and he's tickled with the performance.

Here's a pic of the hull on Friday when we tested he's going to have it gone through and we'll post some new ones later on.

We had a custom cam ground with Ford lifter diameter and the torque was increased considerably over the old cam we had.

We did our basic balance and blueprint flowed the heads and ground a nice custom cam for it . It's been a while since I had used a hydraulic flat tappet cam . The intake and carb was a Dominator and Dart . Good Luck Laz Mesa

Thumbs up Re: Carlos Magnum with MB454

Nice output. I think I saw that boat in the North Palm Beach area a few years back, looks familiar. Do you have any idea what the weight of the Magnum is?

E.S.

How much compression? And what heads did you start with? What RPM did it make those #'s at? Nice job.

Guys the comp on the engine was 9.5:1 the heads were gm cast iron that we ported and matched the cam to the cam is one of our customs duration @.050 was 236 int and 242 ex with lsa of 112 and we also worked the area around the flange in the plenum the hull tips the scales at 4600 lbs but whats good is the hull is straight and flat as can be.
