Exhaust Manifolds

I know that this has been discussed before but why do some people recommend the 360 truck manifolds for the A body small block when they won't fit. I think that it's been said that the right side fits but not the left and for that the 340 manifolds have been suggested but they are hard to find. What about manifolds from the volare / Aspen that had the 360 or a diplomat,etc. Was there a police interceptor 360?
1- the truck manifolds are recommended for narrow bodies because they fit the cramped engine bay and are cheap and widely available.

2- the DS is always going to be problematic because of the seemingly endless array of possible combinations: early, late, manual, column, 360, 318, [brand] heads. beyond bone stock it is nearly application specific. but if you have the time, money and inclination to test fit a bunch of different manifolds, you could probably find something that works.

3- 340 manifolds are NOT hard to find. i don't know why you keep insisting on pushing this fallacy. look, dan, right now, right here, on this forum's very own classifieds there is a set: [FOR SALE] - 68-70 A-Body 340 HP Exhaust Manifolds $550

4- what about [blank] manifolds? i suggest you go back and re-read section 2 from above.

5- yes, there was a police package 360. it did not have special manifolds. and if it did, it would be unlikely for the DS to fit because they came in 80's cars that have transverse t-bar suspension, isolated k-frame and column shift.

so, we are back to our usual starting points, which i will list for those of you still following along:
1- get a car first
2- worry about stuff later
3- you aren't going to make enough power for anything beyond dual exhaust to matter.
