Need help choosing a cam 1969 340

Why did chevy guys go to Ford and Now Mopar 904 lifters.?
One reason is to straighten out their lifter bores without using sleeves
The other is to get better cam profiles
CamCraft and others have developed special cam series for the smaller chevy base circle
good news for MOPAR (and BBC and Ford) is that these profiles give a big long wearing nose on a Mopar size core

here's a quote
'
Custom Mike Jones cam, 202 max area intake lobe Jones designed for Chrysler 440s.

More area under the curve than a longer-duration cam like a Comp 268, extremely fat at 250-275 lift, about 50% more than a Mopar Performance 260 cam.

Fast acting, but the nose is big and reduces wear."

And while the valve is fact acting the Mopar lobes from Lunati have exactly the same paramaters as the Chevy Voodoo lobes, just get to work over the larger area.
The High Rate thought is a myth - don't drink the kool aid

Jones cam was designed for high mileage motorhome applictions whereas the comp XE series has a much more pointy nose
