which has more HP

[midevil1]

anything stock lasts forever as long as its treated what it was intended for. once you start beating on something it shortends its life. you wont seen any of these high powerd diesels lasting 300k just wont happen. stock form pulling a trailer each week yes youll see 300k, making 500hp and 1k torque youll be lucky to see 50k miles at that level...this is relation to any motor. you boost a 1.8 civic motor for miles and it wont live as long as the mother of the son that drives to work everyday for 10 yrs.

I have a customer with 286,000 miles on his Cummins and makes regular dyno pulls in the 900+hp range and runs low 11's all day long. Project X makes 1100+hp and has 240,000+ miles on the clock. The V8 diesels don't last long at these HP levels......Wait, Most can't even make these power levels. At least not wihout a $40K shortblock!!!!

ok my point is has that motor made 900hp for 286,000 miles? thats my point

[Hot-Dog]

900hp isn't uncommon in the dmax world. 1100 is pretty high...

[Hot-Dog]

also common rail can be plenty reliable at high hp levels.

well one pint i think people are missing is drive ability. is a 600hp sbc as reliable daily as a 600hp ls? no its not the ls motor is hands down better. you could never drive a 600hp sbc to work every day and be comfortable with the ls you can.

He is completely right. Why would the Cummins have a 350,000 mile overhaul warranty when the Ford and Chevy only have a 250,000 mile overhaul warranty? It is plain and simple--an inline motor configuration will last longer than a v-style configuration. Same goes with gas or diesel. And for horsepower/torque--if you take a 3.0L V6 and a 3.0L I6, the inline motor will make more power and torque than the v-configuration.

which is why the ford 300 lasts forever, the dodge 4.0 lasts forever and same reason why the 2JZ destroys all with power

Wow George--you really know your motors! When I was thinking of a truck I6 gas motor, the Ford 4.9L came to mind... And I guess you could call the 4.0L I6 from the Jeeps as a "Dodge" motor. Just think about it....Cummins...BMWs...Supras...Jeep XJ...R31, R32, R33, R34 Skylines...the list goes on and on!!!! Oh, did I forget to mention the Vortec 4200???

a vortec 350 or a 5.3?

i can find 350 real easy and cheap..but all the 5.3 seem like they got more power to me

i love the gen 1 sbc's i have plenty of them,but now im partial to the ls,when u buy a fuel injection set up to go on a sbc your gonna have as much in it as a used low mileage ls,If your doing a swap go with the ls,you will be so much happier,and yes a stock 5.3 has more HP than a stock vortec 5.7,My 5.7 denali wont pull a hair out of a cats ass.My C3 sierra 6.0 wont flinch with a loaded car trailer behind it.

[JustN87]

yea think imma go 5.3 lol

just gotta find one then harness and tranny
