new guy needing advice from GA Hello everyone. I am new to the site and had some questions and need advice on. I am building a 1956 chevy truck and want to put a 5.3 or a 6.0 in it and I have both engines. Is the bottom end of these motors the same as the ls1 and are the parts interchangeable ie,cams, heads,etc... I need to rebuild both but which should I use. I am pretty sure the 6.0 becuase of hp. ANY IDEAS????????????????
From the other thread you posted this question in...parts are mostly interchangable with the exception of the 6.0L crankshaft. Some of the 6.0L cranks have a thicker rear flange.
I am building a 6.0liter out of a 2003 1500HD truck for a 1956 chevy truck I am restoring and I need some serious help. I would like to make around 400hp with this motor, but what would be suggested to do this. I would like to put a cam in it and a different set of heads but really dont know what to use at this point. Someone please point me in the right direction. I also have a 5.3liter out of a 2001 suburban that I can build as well if there is any benefit to do that. ??????????????????????
You can easily make 400 with either the 6L or the 5.3L. I personally like the idea of using:
1) 5.3L bored out to use 5.7L pistons. 3.898 is stock 5.7L bore but you can over bore to 3.905--there are alot of quality pistons available but I prefer Diamond or JE (just my preference). Go with a flat top with -2cc valve reliefs.
2) stock 5.3L 3.622 stroke crank.
3) stock 5.3L rods with good bolts (ARP or Katech).
4) a set of stage 2 ported heads (Patriot Performance is a great value for a nice "LS6" stage 2, which is ported with 2.02/1.57 valves & his Patriot Gold valve spring/retainer set), these will give you 10.5:1 compression with the pistons above. Also be sure to get a set of hardened pushrods as the stockers are a bit weak.
5) a smallish cam (such as the Thunder Racing TR224, with 563/563 lift, 224/224 duration and a 112 lsa will make good power throughout the power band, be easy on the valve train and have a nice lopey idle.
6) long tube headers with a free flowing dual exhaust.
7) a good tune is essential for longevity and power.
You didn't mention if you were going to run a throttle body or carb, but in your application I like the idea of running an Edelbrock Performer with either a TB or carb.
And that is all it takes to get 400rwhp...
