TIGHT FIT ENGINE BAY 65 DART / HEDDMEN SHORTY HEADERS
So before long I will be doing an engine swap for slant6 to 360 in my 65 dart . Al long tubed headers are out of the question due to PRICE and fitting them in the car ! so ive been looking for a cheaper alternative source for running an exhaust set up on my dart . after searching the internet and mopar groups I found out what I can run and what I cant . cant - 273 v8 manifolds! why because even though they bolt up they are really restrictive on flow even if my 360 was stock and that the ports are too small and will cause leaks and burned through gaskets!! so I can either run 340 manifold which are expensive or a set of 360 manifolds form a chrysler Cordoba or other 360 B ,C, E body cars or mid 90s 318/360 truck magnum manifolds . these 2 diff3ernt sets of manifolds bolt up and have the same port sizes as my 360 and while they do flow well for stock 340 or 360 heads they dont flow as well as headers! so after searching I came across pics on the internet of someone on here or another mopar group installing a pair of modified Heddemen shorty headers on a 360 in a mid 60s A body . The black set runs 278.99 give or take and the stainless or ceramic coated once run 400-500 a set . According to mopar muscle magazine artical about a shoot out between manifolds and different headers the shorties vs long tubes headers only seen 5 -10 horse power difference . so here are the pics ive gathered to help with my swap and hopefully your s?? you have to modify the driverside to fit around the steering box . mine in the dart is manual .
