I'm really tired of competing against others and comparing builds against those that may be similar and have been posted online sometime in the past. So-and-so did this and joe-blow got that. Before I quit the game, I wasn't sure I wanted to post anything on The Not A Camp Cry Baby Pissy Pants EQ headed 360 I've been asked to build. But it sounded like the owner would like to see some information posted on the engine. Therefor..............
This is the first set of EQ heads I have ever seen, and I like what I see as a stock replacement head.
So, one verse of our 'swan song' as we go out, will be a stock stroke 360 with some Engine Quest heads. It is supposed to be a pump gas only, more race engine than street engine, that can be comfortably driven on the street.
So why are we using a "stock replacement head"?
I've lived long enough to see that almost any head in the right hands, can be made to produce some pretty nice horsepower.
Right now we've only got the EQ-CH318B heads. We have installed a 2.02 +.100" intake valve, relocated the rocker shaft studs for better geometry with the longer valves and Chevy roller rockers, did a real quick port job on one intake port only, and picked up 20 cfm @ .450", 30 cfm @ .500", 40 cfm @ .550", 40 cfm, @ .600 and 35 cfm @ .700". Yes I measured the flow at .700" though there is no plan to go there.
Right now these iron EQ heads flow the same, on our bench, as the 2.02/1.60 CNC ported aluminum AFR 1399 head for the small block Chevy. We used the AFR 1399 head on a 383 small block Chevy and it made 518 HP on pump gas.
It should be fun to see what this 360 will do.
