SB 318 Wanting to build for a 67 Dart GT

Are the heads a good set or would i need a different set. And what would be a good cam for a 60 over 318? It had an older holly hi rise intack on it when i got it and ran good the carb messed up and washed the rings out of it I think.. I was thinking about doing a re ring and bearing and gaskets and running it..The car will be a street car and has a 727 and an 8.75 with 3.23 sure grip.. Or would i just be better off going with a big block.. Thanks for all the help and im put.. I will get the heads off to give a pic of the pistons And the number that is on them.

Your more worried over nothing really. This is an easy "to do thing."

A re-ring job and gasket kit is inexpensive to do. Miles ahead of the big block.
IMO, the big block is way more expensive to do since a lot of stuff has to be changed out starting with the tranny, and maybe the rear end, then brakes etc..... the list rolls on.

IDK about the casting numbers exactly for the heads. Sounds like 2 different heads. I do not have my book in front of me, so, as a basic, they all flow the same within a few cfm. no need to change them out for a Mello geared driver.

A good cam depends a lot on what you want out/from the car. I like a cam of approx. these duration @ .050 specs; 216*/228* give or take 2* on either side. On a 110 or 112 C-line.
My Crane cam I used. An excellent driver with good response and power. Mello idle and good mileage.;

I'm sorry to report that the carb did not mess up the engine but the way the carb was tuned by the last person to touch it .. or not... allowed the carb to run rich beyond Donald Trump and killed the engine. IMO, IF you do not have skill to do this tuning chore, find someone willing to teach you, grab a book and a great help is a simple 02 sensor and gauge to show you rich or lean conditions. Edelbrock makes a simple and inexpensive unit to use.

Find out how deep the pistons are in the hole. This, times (Multiply) the measurements of the head gasket and cc amount of the head will give you the compression ratio.
This would be great to know.


Running headers? A higher stall converter than stock? Anything else?
