whats better J or X heads
Thanks for all the feed back everyone. I was wanting to build a 400 hp 360 . I have lots of old issues of mopar muscle and mopar action but one issue of mopar muscle has an article about a guy that likes to take mostly stock parts and a few after market parts and he made 378 hp with: thermoquad,comp cam , J heads that had a light porting /polishing etc. After market flat top pistons and headers. My project 65 dodge dart 2 door post car weighs in at around 3300 Lbs give or take. I figure for a daily driver and once in awhile to the drag strip on amateur night a mostly stock 360 with performance cam 4 barrel , flat top pistons 10:1 compression , 360 J heads with ports gasket matched valve job bowels cleaned up ,air gap dual plane intake shorty pretzel headers from hedmen headers, 904 with racing guts full manual valve body, 8-3/4 with posi and 3:91 gears should be more then plenty for that little Abody car ?
