Hi, if the motor is an HP engine as in Little Red Express truck or Cop car (4BBL) it would be the same specs as a 340. I understood the cam specs were the same, 340-360 HP engine. If a 2BBL, then just a regular plain Jane cam spec.

4BBL is a different cam...
.430/.444 - 268/276 cam#4041998
Looks like it's the same as the early 340 cam.

I believe this is a hotter version of the stock 340 cam. The stock cam is 268/276 advertised, 210/220 @.050", 429/444 lift, 114 lsa IIRC.
The P4041998AE specs at 268/276 advertised, 228/235 @.050", 429/444 lift, 114 lsa.
The '68 manual trans cam is different.

This is the normal cam for pickups and cars of that era.

Mopar Performance has changed the info on the @ .050" numbers over the years. I read somewhere they used to measure them differently than everyone else. Who knows...
1st pic is from a 2005 MP catalog. 2nd pic is the paperwork that came with my cam recently.
Mopar Performance has changed their 268/276 cam lobe design for increased .050" lift over the years.
Those numbers I posted match numbers the stock 340 cam in my '71 Cuda and '73 Duster had at .050" according to my notes.
BTW, the '68 340 with manual trans. was .444/.453 lift .276/.284 duration.
Ask a stock or super stock racer they should know.
Centerlines are all over the place. Duration numbers we’ll moved.
I sure wish they’d get there crap straight or quit!!!
OH! Wait, they did quit!
Mutha-frackers!!!!!!!
Oooops! Wrong thread !

The 228/235 number for that cam is a pipe dream.
The specs for a stock replacement “2bbl” cam are:
Clevite 229-1663
SAE duration 278/278, duration @.050 203/203, .410/.410, 109.5lsa.
SAE duration is .006 divided by the rocker ratio, so .004 in this case.
