Dual quad intake for 273

You can run holleys (not inline) with open spacers. I personally not a fan of edelbrock, but only suggested the holleys due to the smaller cfm. As suggested some old Carter's would be good to run. Go with the smallest you can find/afford to keep your throttle response.

I'm not sure on what my motor is putting out, somewhere between 260-300. I'll find out when I run it down the 1/8 mile in August. Cam is a comp thumper cam. Cam specs are 235 in/249ex @ .05 . Advertised duration says 287in/307ex. Lift .497in/.483ex with lob separation At 107. cam rpm range is 2200-6100.
