Magnum 5.2l vs 360 LA?

Well, if you're not gonna open them up, and it's for a two-gear streeter, the 5.2 is a hard combo to step over to get a lo-compression 360LA. Even the roller cam in the 5.2M is about the right size for this. I have it listed as;
251/125/111.5/264/31.5 overlap/113LSA/ in at 110, the Ica is 55* and the lift I have recorded is .432
With a 13* split pattern, you should be able to find a sweetspot.
>The 5.9 cam I have listed looks a lil nicer, but everybody seems to want to throw it away. The specs I have are;
249/131/112/269/41 overlap/109LSA/ in at 104.5, I get an Ica of 49* Yeah you should be able to make a lotta pressure with that. Lift is listed at .410/.417

> The 2bbl cam in the 360LA, IIRC, is
252/124/116/260/32* E-overlap/112LSA. Installed at 110, I get an Ica of 56*. This cam is a lot like the 5.2M cam; but favors power extraction (4.5*) so it may be a lil better on the hiway. the pressure will be down a tad, but maybe not the force so much.
at 160psi and at 3.91bore; the force on the 5.2Mrod is 1921 pounds. For the LA ,132psi on a 4" bore comes to 1659..
By the time that gets to the flywheel, I'm seeing 265 ftlbs for the 5.2M, versus 247 for the LA; so the 5.2M is definitely a lil stouter, 7% by the math.
IIRC the 360 lift is also around .420

Like has been said; the 5.2M is a pretty stout lil item.
