Mopar 318 heads

I'm going to run the stock 234 valve train 3.73 gears, 904 transmission with a stock converter im guessing. I'll run a cheap set of headers 2 1/2" exhaust and some glass packs to start with. What is you advice on a cam for that set up?

Stock converter? That changes the cam mentioned above. Since that is the case, a stock converter, a duration @.050 not more than [email protected] will work great! Been there done that exactly like your doing.
The 228 cam might be a bit much for the stock converter even though you have 3.73 gears. This I’m not sure of.

Use Summit headers and there dual exhaust kit and if you can splice in there H pipe kit, go for it.
