I'm trying to choose between and 454 and a 383. I have limited funds so I'm trying to figure out what's the best bang for my buck. I have experience in engine rebuild so I was thinking about buying a performance short block and build it up. I'm having the hardest time choosing so I'm relying on everyone's experiences in what engine to use.
-
5.9 Cummins or Duramax..........
-
What vehicle for what purpose?
-
In my 87 half ton.
-
with a 383 you pretty much made the limit on performance wise with the 350 block but if you get the big block you will have a lot to choose from later on.. you know what i´m saying... as in the 454 is just the tip of the ice burg for massive torque
-
You make a good point.
-
Have you considered an LS swap??? for the money your talking to build a 383 our a 454 you could get a low mile LS engine and do minor mods and get the same our more power.
-
^^^^ That^^^^
-
I'm keeping it carbureted. Im not looking to do a swap.
-
you can still gain a mass amount of power with a carbed ls1. they honestly offer the most bang for the buck.
-
If its a 4x4 i'd go with a big block.
-
I vote 454 as there is nothing like having awesome low end tq.

How difficult would it be to wire up a LS motor with fuel injection?
-
It all depends, I would think you could do the swap for under 4000.00 for everything if you do your shopping and research

this were I got my 6.0 from for 91 V3500 I have about 3000.00 total in my swap so far with a few more little things left to do . But i went with a Denali LQ4 with a few mods and new headers , ect I could have gone cheaper

There is a couple of threads going on here with LS conversions:
Mine is here, although I am doing it on my spare time. If you get a complete wiring uncut from the donor you can do it yourself.

duramx wont fit in our trucks right?
-
What's that old saying?
"there's no replacement for displacement"
Or something like that?
If \ when the 350 goes out in my suburban I plan to go with the 454. I don't care to run a 4x4 suburban over 100mph so top end HP isn't a big deal. However, big reserves of torque on tab can be a lot of fun !!
-
I hope you're giving some thought to a new tranny too, if you go with the big block. With limited funds I'd stay with the small block and build a 383 stroker. It'll have plenty of torque to keep a smile on your face and be a little better on gas too..

Anything can be made to fit.
Here is a duramax conversion: http://www.lonniesperformance.com/82chevyduramax.htm
