so i'm getting ready to build my 5.3L for my 96 1500
Plans are as follows:
Block: bored to accept LS1 pistons
Heads: Patriot 243 LS6 / LS2 2.055"/1.57" 64cc
Cam: 2xx/2xx .600/.610 114 still undecided on durations
LS6 intake with TB, both P&P
Longtubes
Any thoughts or suggestions? This will be my first motor build. I've read a lot but still feel i'm missing a lot of things
Thanks!
I would buy a 6.0. cheaper to buy a used motor than to machine and you'll have more cubes. But if you want a bored 5.3 aka iron 5.7, I know were one is. heads will be good, You might want a better intake. Remember that with the iron 5.7 the biggest you can ever go is a stroked 383... with the 6.0 you can go WAY higher.Originally Posted by e3mcgrath
already have the motor, nothing invested but time in it so far
arent able to port and polish at LS6 intake

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
You asked for a suggestion. I would also advise getting a 4l80e.
Get a smaller cam or get a 4000 stall and 4.56's.
a low 22x cam will be just fine for that build with a 3000-3600 stall.
s10 with 4l60e and cammed 5.3 on the road!THREAD

Is there a low 220 with that much lift? I guess someone makes one. Seems like most of the .600+ lift cams have a lot more duration than most truck builds need.
it's an LG motorsports cam. since i plan on basically having an iron block LS1 i've been asking around on f-body and GTO forums and that cam is a very popular choice
"That" cam? Which cam? I know you pretty much have to buy one of theirs to know the specs but it sounds like you're referring to a specific cam. What are the spec? Wait, they won't tell you, huh?
After the 1st go round in this topic I looked a very little amount of time and found the 22X cams usually coming in around .560-585"...anything near .600" was high 22X intake and low 23X exhaust on a much more difficult to live with (at that duration) 112 LSA and only near .600"...the .600"+ cams were in the 240's with 108-112 LSA. For that you'd need a 4000 stall and 4.56's minimum to actually be able to drive it. Yes, 3600 is not much less than 4000.....
