Well, since I picked up a 5.3 recently I have been thinking about my plans for it. This motor will be going into the S10 in my sig.

Plans:
10.5:1 Compression 5.3
Milled 862's .030
224/224 112 (ish)
Pushrods/Springs
New Lifters?
Ported LS6 Oil Pump
LS6 Intake
Ported Throttle Body
LS2 Oil Pan/Windage Tray/ Pick Up
Current Performance Wiring Harness
Hedman S10 Swap Long Tubes
Circle D 2c
3.73's

Im looking for 350+RWHP

What do you guys think of the set up? Ideas? Thoughts? Suggestions?

 

Or not, lol.

 

What a noob setup.

 

What kind of dynamic compression are you going to have with the 224 camshaft? I would want close to 9.0:1 dynamic compression for efficiency with 5.3 liters.

 

its so perfect we dunno where to start.

 

I have no idea to be honest.

Pfft. lol

 

Get an oil pan from an H3 that way you don't have cut up your pan or crossmember

 

If I had the engine all apart and was doing all of the work you mentioned, I'd definitely put new lifters in for some cheap insurance. A set of LS7 lifters is something like $120 from SDPC.

I like the setup, sounds good. What's the stall speed on a CircleD 2c?

 

It seems like a very "standard" setup. 10.5:1 is very common (LS6 stock CR), TR224 is used a lot on here, etc.... no issues that I see.

If it were MY setup, I would:

- do the entire valvetrain (lifters, pushrods, springs, retainers, and even a double roller timing chain)
- depending on planned RPM, a set of direct swap ARP rod bolts (these CAN be swapped without honing the rods)
- depending on mileage, cleanup hone/new rings and replace all bearings (allows for above honing of rods after bolt swap)

While my "suggested" stuff is "entirely unnecessary", it's easy (and cheap) to do before the engine goes in and provides some serious insurance.

Small points DozerDan saying the H3 pan are beyond my input so go find a list/step-by-step S10 swap guide to give you heads up on "swap specific" issues.

 

From what I remember reading, the H3 pan hangs down below the crossmember. Im lowered 4/5, lol.

I was wondering about using the LS7 lifters. I THINK the 2c is like 3200, but Im not sure.

I forgot to write them, but these were also being thought about. I am pretty certain I will run ARP rod bolts and head bolts.
