Hi, guys, rebuildinga 300D engine ,stroked, to 450, 10.5 :1 , hot heads heads.-- set up originally w solids from Mopar, 300D rockers, around 280 degree advertised stock, about 430 lift ; the cams listed on hot heads site with solids seem somewhat hotter,and you run into vacuum/ brake issues in a big car like a 300D; do not want to back into hydraulics . Has 11" converter. We all over cam at least once....on street. Wary.
Also noted HH engine masters 380" did the job at 5500 RPM, kind of saying 270 area cam is a good deal, unless planning 6000 +. = not me with stroker.
So bought a new Isky solid about 268 advertised , about .430. Interesting, on duration question, as a 300 lettercar guy, one of the highest specific out put MOPAR street engine is the 300 J wedge, crossram, 390 HP same as 440 sixpack, but a 413. it had 268. They Backed down from 270-280 in 55-57. I know ,hemi. But J had CI headers, cross ram. factory dual quad WCFB manifold is garbage.
Point of all this went looking for solids, higher lift , 275 degree area , comp had something in the .480 lift area,"if we can get a core" ; but customer service there is garbage now, guy disappeared after quoting a cam, was available nitrided too. Using howards solids with oil hole.
Saw new roller steel HH cam , would like to find the answer here at HH. What was in engine masters engine? Comments really welcome. thank you, John
