Re: {Chrysler 300} Original Ram Engine Block Cracked :( What to do?

Might go 9.25 compression on 440 too , given no sunoco 260 in 2023 .

You almost have to back off timing on J/K

from optimal with todays gas More cubes fixes that loss ? or else you risk detonation you might not hear when “in it “ = piston hole or hidden damage .

I do agree crack in outer water jacket you can get by even with pour in block fix . I have a Buick 60 electra 225 like that for 30 years . Long, 6” crack between two sidewall core plugs . Attitude was nothing to lose , it worked . .Depends how wide and where

Cast iron cannot be welded , period , in engineering sense . Can cause more harm than good . it will crack right next to any weld attempt at room temp. Braze maybe but to do right whole block needs preheat , impractical .

449 block

makes sense to me .. I think made sense to George in his legendary fast J too

So the machine shop showed me the cracks in the water jacket areas of the original 413 from my 300K. They don't want to fix it. I'm torn between giving them the other 413 I have or just building a 440. The 440 is way more common and has numerous piston choices and will hide neatly below the short rams. I really believe the Rams operate best if they are on an original engine with original carbs and camshaft. Am I wrong?

I was really hoping to build a 413 using an original ram engine cam. I seem to recall someone was reproducing the J/K camshaft?

Looking for recommendations. I've had this car 33 years and want to make sure it's user-friendly for the next generation and perish the thought... I've had a brand new factory Gen III Hemi sitting in the corner for ten years. I've been imagining it painted torquoise with a gold intake.

Help me out here...
