Doing this soon maybe anyone can chime in on what gains they have experienced, i am hoping for 400 whp, i put down 337.

They are patriot stage 2 5.3L heads with a comp cams 231/237.

i am doing upgraded oil pump, double roller timing chain, and pushrods, the heads come with .650 lift patriot springs.

all i need is the gasket kits and install with a tune and im flying hopefully!

any opinions, questions, or comments let me know im excited myself

 

Mine have served me well since 2003 with no problems. Do your homework and optimize SCR, DCR and quench. Building a good motor is all about combo matching.

 

measure ptv, if running with Ferrea valves

 

a local car with that setp and a 90/90 made 450/410 rwhp/ tq. also trapped 121 in the quarter.

 

why not go with the 233/239? i heard the 233/239 makes more midrange and a little more up top.

 

its whats coming in the setup

im hoping it is good for daily driving since i like to do that a lot haha, which is also why i didnt wanna go with too big of a cam

 

Check PTV clearence and mill the heads if you have the room.

 

I have that combo and my car makes 415 to the wheels.

 

Hopefully on a mustang dyno because I made 406 on the 233/239 through a 9" with cam only.

 

here my setup:
01 ws6, m6, kooks lt 1 5/8", x-pipe true duals dynoflow bullets dumped, PP heads LS6 2.02 in/1.57 ex 59cc, Patriot gold springs (.650 max lift) Comp Cam 231/237 .589/.595 112 lsa love the sound "lopey", Comp p-rods 7.425 helped quiet down the valve noise, Comp lifters, Cloyes steel hardened single chain, self ported oil pump/shimmed, port/polish tb, Granatelli maf 90mm, SLP lid, K&N filter, TR55 plugs, stock wires,stock gears 3.42, stock clutch. comes out to 418 rwhp, 389rwtq, next mod will be 4.11, 90/90.

i made 420rwhp and 385 rwtq with that combo and did 445rwhp on a dynojet. I did that on a ls6 intake and t/b and just added a fast 90/90. I cant wait to get it retuned. I might just throw in the ms4 for fun. Did u already buy the cam, if not mine will be for sale shortly??
