Suggestions on my setup Suggestions on my setup.
LQ4 364 stock shortblock (upgraded rod bolts)
Absolute Speed 5.3 Heads
(milled to 59cc)
(2.02 intake/1.57 exhaust valves)
(Comp Dual 978 Springs)
.040 Head Gasket
FMS F13 230/232 .595/.585 112 +4
LS6 Intake
Ported Throttle Body
TR LS6 Ported Oil Pump
SLP Double Roller
42# SVO Injectors (Over-Kill)
ASP Pulley
Hooker Super Comp LT Headers
No Cats/ True Duals
Heads flow pretty good.
Exhaust flow seems a little low.
Lift: intake exhaust
200 141 114
300 202 158
400 255 197
500 293 214
600 313 227
28inches H20
3.9 inch bore.
I calculated
11.1183 CR and 8.61295 DCR
Quench @ .032
Motor will be backed up by 4L80E/3200 Stall/9” /w 4.56 Gears.
Looking for 400rwhp @ 6200 rpm.
Am I close to my mark or do I need to re-think my setup?
I'm not 100% sure on the cam. I was looking smaller but I think the F13 should be nice in a 6.0L and I'm close to Futral so hopefully I can get them to tune it.
Should I pick a cam with a bigger split to help the exhaust flow?
I have everything except cam and head gaskets.
Let me know what you think.
Thanks

Looking for 400rwhp @ 6200 rpm.
I'd like to shift at 6200 or below.
400rwhp being my hp power goal and 6200 being the highest I would want to spin the motor.
This is going in a 62 Chevy II.
Should be about 3000lbs or less.
The car will be more of a weekend playtoy.
It will see a few trips to the track just for fun, but nothing serious.
I'd like to run some high 11's/ low 12's and I'd be happy.

I've been reading posts with people with LS1s, 5.3 heads, and small 224 cams making the power I'm looking for.
How much of a difference is the 6.0L going to be?
As long as I get the compression up to be the same I should make the same or more power correct?
Bigger bore and a few more (18) cubic inches can't be a bad thing...
