[QUOTE="Garbage_Mechanic, post: 1544424, member: 1610"] I haven't talked about it much because I don't like to brag, and it isn't in the truck yet but here is a little info on my Swamps ported engine I've been sitting on since late 2017...... It was built to be efficient, reliable, fun to drive and great to tow with including over 10,000 ft elevation. It is pretty simple with ported heads, 160/30's, Adrenalin HPOP and SXE 364.5. It was broken in and loaded on Swamps engine dyno, so crank HP and Torque. I really don't have and idea how to convert to expected RWHP. Peak torque is 1010 @ 1690 RPM. Over 900 ft lbs from 1280 to 2640. Over 800 ft lbs from 1100 to 3000 rpm. Glad I put Manley rods in it even though they arent "required" Peak HP is 471 @ 3000 rpm. Over 400 hp from 2200 to 3400 rpm. How much of this performance comes from head porting? I don't have a way to know. The missing Swamps Dyno Mule info we are discussing is the reason I did it. But I can't recall the gain they made on the dyno mule. [/QUOTE]
