MackOnly Posted December 31, 2017 Share Posted December 31, 2017 Looking to replace original 350 in my Super Dog with a higher horsepower Cat engine. Anyone got recommendations? Pros/cons? Sent from my SM-G930V using Tapatalk Quote Link to comment Share on other sites More sharing options...
0 HeavyGunner Posted January 1, 2018 Share Posted January 1, 2018 It would all depend on what YOU want and how deep you're pockets are. I personally like the 3406 E model but like everything else it all comes down to preference. Besides what's a guy with the MackOnly moniker want a cat for? 😄 1 1 Quote The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living.The government can only "give" someone what they first take from another.

0 theakerstwo Posted January 1, 2018 Share Posted January 1, 2018 It sure is easy to replace with a Mechanical E 7 and if engine is done right they will work along beside of a 425 cat and last many miles with good fuel mileage with less weight.I have built two of them from a 300.Using a 400/427 cylinder kits injectors and turbo with pump maxed and timing set two degrees faster. 1 1 Quote glenn akers Link to comment Share on other sites More sharing options...
