Hey ! You got some good info. posts there. Here is some more.
I have a 55 270. Sent the brand new, yes, brand new Cam to Hot Heads & had a 3/4 grind put on it. Got an Offenhauser 3 duece intake from Vintage Parts or Vintage Speed.
You want a Stromberg 48 to run on the center port of intake, has a little more cfm flow than the 97's, if your'e going to run progressive linkage.
I went with a Hot Heads adapter & 67 727-A Torqueflite short shaft tranny & 2,500 R stall converter.
Don't have much space for drive shaft in my 30 A Roadster.
You can get a 97 or 48 from Warren Todd at- email@example.com
Maybe one of you other Bad To The Bone early Hemi guys can answer my question ?
I want to get my "LIL" Red Ram comp. ratio up to 9.5 or 9.75 to 1.
If I do it by milling the heads, why can't shimming the rocker arm stanchions work for correct lifter pre-load ? Know where I can get dome pistons, but that's the spendy route.
