360 magnum cam choice

7dart0 said
my engine is a 2001 360 magnum block stock bottom end, hughes EQ heads with 2.02 intake valves,TTI step headers, edelbrock performer rpm air gap intake, 750 proform mech. secondary. cam is crate 360 cam supposedly I think its smaller. stops pulling around 5800.
A904 with 2800 stall with forward manual valvebody, 8.75 w/4:10 suregrip
I've gone 12.40 @ 110 in the 1/4 mile with this setup

lookin at Oregon cam #1357 grind
230/[email protected]
112 lobe separation
.515/.515 w/1.6rockers

this custom one from a member
bullet cam
237/[email protected]
108 lobe separation
.550/.550 w/1.6 rockers

Between these two, I'd go bullet if I still had pressure enough left for to have fun as a streeter. But the thing is with a roller, that [email protected] might translate to 290/300/108/79overlap. and in at 104 say would get you an Ica of 69* maybe. And that in a 9.5 Magnum equates to just 146psi, so not real snappy at typical street rpms. Thank goodness for the 4.10s and 2800TC.

But guess what, the Oregon 230* could have the exact same 69* Ica so makes the same pressure, but with a loss of 16* of overlap, will definitely make less power at the track. 283/291/112/63overlap

But if you got the Oregon 230 ground on a 108, you would be able to reset the Ica to 66* and might get 151psi, with some overlap back; 283/291/108/71overlap.and a lil more street friendly, at the expense of ultimate power, as compared to the Bullet 237.

In my street 367,I ran the Mopar 292/292/108/76overlap for one summer at 11.3Scr/about 185psi. With just a 9.44 starter gear and a manual trans, I was only too glad to get rid if it. I would entertain using it now tho with my more 292-friendly gears.
I modeled with clearance ramps of 53 and 55 degrees, guesses to be sure.
and elevation at Sea-level.
