2stacksuperdog Posted February 5, 2013 Share Posted February 5, 2013 Change the turbo and injection pump. 2 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-161989 Share on other sites More sharing options...

2stacksuperdog Posted February 5, 2013 Share Posted February 5, 2013 I'm not positive but you might also have to change injectors. That also makes difference if mechanical or electronic? If electronic you have to start playing around with computer. 2 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-161993 Share on other sites More sharing options...

2stacksuperdog Posted February 5, 2013 Share Posted February 5, 2013 That's a GOOD engine I would say turbo, injection pump, maybe injectors 2 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-162000 Share on other sites More sharing options...
theakerstwo Posted February 5, 2013 Share Posted February 5, 2013 If its not a maxadyn then i would get some one who knows how to set fuel out on it some and when its done you can pull with a 350 and no one will know the difference. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-162001 Share on other sites More sharing options...
2stacksuperdog Posted February 5, 2013 Share Posted February 5, 2013 i think your able to shim something in the injection pump that increase fuel pressure thus increasing hp my dad did it to his '93 E7-300 1 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-162002 Share on other sites More sharing options...
David Posted February 5, 2013 Share Posted February 5, 2013 Why stop at 350? For the same cost you can make it a 400. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-162004 Share on other sites More sharing options...

David Posted February 5, 2013 Share Posted February 5, 2013 A good parts counter person at a Mack dealer can look at the inframe kits for the 300, 350, and 400. Look for different part numbers on items like pistons. With the VIN on trucks with the three different engines you can check the injectors, cam and turbo. Only other difference is pump settings. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/29798-what-would-it-take-to-convert-a-e7-from-300-t0-350hp/#findComment-162008 Share on other sites More sharing options...
rsb502 Posted February 5, 2013 Share Posted February 5, 2013 With a mechanical E7 350, the fuel system flows plenty for about 450hp you just have to get the pump set up and advance the timing a few degrees. I know a lot of people change parts looking for power but with a mechanical engine you can make plenty with what you have already, and its cheaper than swapping parts. If you really want to swap parts get with a trim diesel or another good diesel shop and get the pump set, timing advanced and some aftermarket injectors and turbo and you can make over 500 to the wheels pretty easy with an E7.

rsb502 Posted February 6, 2013 Share Posted February 6, 2013 Damn phone, Antrim Diesel,not trim diesel, they have a website and can do whatever from pump tuning to full on race truck. Did anyone notice the Dyno days there are pretty much owned by the Cat's, last year one Mack made almost 1000rwhp, Ill bet it was an E9!
