V8 273 head question

Romulo Roderiques said

OK here is my dilemma. I have an early 65 Dart and swapping over to 4 barrell carb. I'm having a difficult time finding the correct manifold due to the weird bolt angle. What choices do I have in newer heads? I don't want to change the cam and want to keep the internals stock.

Thanks for your help.

Put some 66 or 67 273/318 heads on it... They are still closed chamber and won't decrease your compression, and will have the 'new' bolt diameter and angle where you can use any "LA" engine intake and not the special 64 - 65 intakes which are fewer and farther between....

Also be sure to replace the timing chain with a double roller... The stock 273/318 timing chains are junk and stretch too easy and may jump a tooth...
