318 build #2 "cost minded" for the '74 Duster

Besides the 8007 (which I really like that intake) usually having the spread bore, I believe the runners are a little smaller. I've used the 8007 and liked it. I just think the 5.2 might benefit from the Stealth. Nothing proven yet, of course.
Just FYI Chrysler Power magazine had an article about adapting the LA intake to magnum heads back in the 90's. They made some adapters out of some small tube/pipe stock, cut it to match the angle on the intake on one end, flat on the top, slotted the intake bolt holes, and used some longer bolts to put it all together.
