LS1 build
 

I think I'm getting everything figured out for this LS1 build.

LS1 stock block
LS1 stock pistons
LS1 stock rods
All new rod, main, and cam bearings
EPS 222/226 cam
PRC lvl 2.5 5.3 heads
LS2 timing set
LS6 intake
Truck Oilpan
New oil pump (more than likely stock pump, haven't decided if I want to go high volume)
LS7 lifters and new lifter trays
75 dry shot
Underdrive pully

Hoping for 400rwhp through a Circle-D 3200, PBlvl2 60e and a transfer case on 3.73. May be a bit of a stretch ... but hey, I can dream can't I? :lol:

Doubt you will see 400 wheel hp, maybe flywheel. Still should run good.

Why are you going with an LS1?

Because I found it dirt cheap.

I can see a solid 360-370 rwhp

Wouldn't hurt my feelings any.

I'm probably going to go ahead and throw the 255lph pump in my tank while the 5.3 is in it and have it dyno'd again. turned over 310/301 before running out of fuel pressure @ 5300RPM on a mustang dyno. Already running LT's, efans, and 91oct. tune.

The 310/301 was @ 13.4 AFR @ 5419RPM w/40.2 lbs of fuel pressure, it started leaning out @ 5261

Would be nice to see the difference I get between the two and get some dynojet numbers when the 5.3 is running at full RPM.

I have seen the LS1 Camaros with a good tune, full boltons, mild 224 cam dyno 390-400RWHP.


I'm just gonna take a guess and say you should hit the 370RWHP easy.

Here is the timing set I decided to run.

Copy cat..lol..That is my exact setup!Down to the 75 dry shot.. I went with the ls1 for the alum block wieght savings,and rpm potential. My truck put down 387 rwhp/377 rwtq
with my old 216/218 cam..The PRC 5.3 heads make decent power..But I could care less about numbers, my truck pulls Rustangs/Lightnings on a regular basis...and is fun to drive

Good luck, and I can tell you first hand it will run really good!

u :nono:

Not sure what to think of the last post.

That is a good looking timing set. Looks much better then my sloppy ass ls2 chain. What is it and how much was it? I am going to be doing heads some time down the road and plan to swap out for a tighter chain.
