Cam selection help
IMHO, that Comp XE284 cam would be a real dog with the stock converter.
- 240/[email protected] is a pretty big cam for any 360, and asking a 360 to run well with a big cam, 3.55 gears, high elevation, mild heads and no converter is setting yourself up for very underwhelming overall performance.
I would call Bullet cams and have Tim Goolsby spec you a custom cam based around the converter, weight, usage, and elevation.
As a baseline, I would be looking for something no bigger than [email protected] on the intake and ground on a 108° or tighter LSA. You need to generate explosive torque to accelerate out of the slow corners, and a small cam with a tight LSA would certainly help in this regard.
The small cam with a tighter LSA will help with dynamic/cranking compression also which is helpful at our high elevation.
Stock inexpensive auto parts store replacement Dacco converters can run pretty good if you don't overcam the engine.
Here is a cool example of a small cam/stock converter getting it done!
This awesome 4 door Valiant was on Moparts years ago and I saved the info.
70 Valiant 4 door that weighs 3,320 with Driver.
The best run was 11.96/113 but it typically went 12.0's in decent air.
Typical 60'was low 1.70's
- 40 over 360 short block. decked, 10.51comp
- reversed cast dished pistons, good rod bolts.
- J heads pocket ported with 2.02 int. valves and 273 adjustable rockers.
- Old Manley cam. .443" lift [email protected]. lobe separation was around 108.???
- LD340, 1" 4 hole spacer and a Vac. 750.
- Hedman 1 5/8" headers, 3" exhaust with ultra flows dumped at the axle.
- 904 trans with a (cheap)Dacco 2,400 stall replacement converter
- 8 3/4, 3.91's 8"x 26" slicks.
- 6 cyl. torsion bars and Competition Engineering Adjustable front shocks
- 002/003 SS springs with MP 50/50 xtra long rear shocks
