I know theres 100 million cam threads out there for the 5.3 but I am having a little trouble finding anyone in my shoes exactly. I dont want to waste $400 on a fresh engine build to tear it apart because Im unhappy with my choice.

Ive been primarily shopping Texas Speed cams simply because I can get a damn good mail order tube but am open to what ever. Heres my build specs.

1994 2wd SCSB
NV3500 from a late model s10. Tighter gear ratio with 3.49 first rather than 4.01
8.5 Ten Bolt, Detroit Tru Trac, 4.30s, 9in outers.
Roughly 3900ish pounds w/ driver.

Motor build is spec'd as follows
2003 5.3
.030 over 4.8 flat tops (for the hell of making it a 327 )
Stage 2.5 CNC'd 862 from texas speed. Milled .030
Flat tops and milled heads net me 11.1:1 static compression
Debatable depending on cam 1.75:1 Roller rockers
Head gaskets will be spec'd depending on thickness needed from proper squish. I have .4 compression to play with to be safe on 91.


The goal of the truck is to make a nice, fast enough daily driver. Im not afraid to drive something with a somewhat higher RPM range as the small block in it now comes on at 3000rpm. Granted I would prefer a tad lower. Im going to take it to the track once and a while and Im not looking for a bullshit peak horsepower number. Im not afraid to throw rod bolts in it to spin it either.


Now TSP suggested a 220/220 cam which is .581/.581 lift and he recommended a 112 LSA to bring the power in fastest. Its not that Im against the suggestion its just I dont really want to be left wanting more. Ive seen a couple guys running nice mid 12s with the 224/224 cam they have in a 5.3. I would be really happy with a time like that but dont want to kill the drive ability outright so Im looking for suggestions. Part of what scared me about the 220/220 from them is I felt like the guy had tunnel vision towards suggesting that cam the second I said it would be a DD. Secondly he said to only expect around 380hp at the flywheel which I was kinda of taken back at. This is my first LS build but to not even build a motor in the 400hp range was kinda odd sounding to me.

Thoughts suggestions comments?

Go with a custom cam. There are only a couple of bucks more than you will get what you want.

I'll give comp a call on lunch. Any other company recommendations? I'm new to LS motors and would like to give someone a call that specializes in them more so.

Go over to ls1tech there is a few. There is a guy name Kip from LS Camshaft, LT Camshaft that knows everything about cams. He will spec you a cam.

yes use Kip from Cam Motion, COMP has had lots of QC issues in the last few months.

380 flywheel hp is stupid low, I made 389rwhp/366rwtq in my built 5.3 with stage 2.5 heads, and a tr224 on a 110 with full boltons. which is more like 480ish flywheel.
