Hello to all, i am building my 360 for my dart and am wondering if it will reach 400hp at the crank. i think it would but i am new to mopars since i am only 18 and i live nowhere close to a dyno so there really is no way for me to know and my dad who had a charger when he was my age and helped me build this car wont allow me to take it to the track. I have seen similar buildups and they have made it to 400hp i have even seen a 318 make it to 400hp with a similar combo like mine so thats what i am going on heres the specs on my motor:
small block 360
bored .030 over
Keith Black Hypereutectic pistons (not flat top pistons)
Compression is at 10 to 1
stock crank
stock rods (i think not sure)
Ported 2.02 1.60 valve X Heads
Comp Cams 284XE Hyrdraulic Cam i think the lift is at .507 .511
Comp Cams 1.6 ratio Aluminum Roller Rockers
Comp Cams lifters, pushrods, valvesprings etc.
Edelbrock Air-Gap Intake
Holley 670 Street avenger carb
TTI Headers
2.5 inch exhaust with Flowmaster 40 series mufflers all the way back
and i think that is it seems like it would make it to 400 hp at the crank the way i am looking at it tell me what you think THANKS!
P.S. how much does a dart with a 360 and a 727 weigh in at? one with a 340?
 
Depending on your gears and converter, I would consider a 750 cfm carb, but the 670 will be fine for the street. Speaking of converters, spend the cash for a good quality unit. Also, don't overlook the small things like a 3/8 fuel line and pickup tube in the tank. If you pay close attention to the details like that, you could probably beat the 400 mark by a fair margin. There are much better flowing and sounding mufflers than the 40 FM as well (you make like their sound, to each his own).

As for weight, the 340 and 360 will weigh about the same, although a 340 had heavier pistons and the 340 steel crank is heavier. Depending on how your Dart is equipped and the year, I would guess 3200-3500#. The post 73 cars really packed on some pounds, especially with PS, PB, and A/C.
