273 Suggestions

hi, the cam can be replaced with a good grind. Isky makes a E4 grind, its a solid lifter cam, works very well in a 273. this is a short duration ,tight lobe center cam, the cam will pull 6500 RPM easily. idles at about 800 RPM. will work with a stock convertor. you can use the mopar thin head gaskets to help bring comp up some. also ,surface heads to 57,3 cc, these two changes will boost comp to about 9.1 . more than enough for todays gas.
