Just curious what rwhp yall think I will be putting down on my new motor.

"383"
12.6:1 CR
Eagle Forged 4340 3.75 Stroke
Eagle H Beams 5.7 Length
SRP Forged Flat Tops -5cc 4.030 bore
LE3 Heads
42lb Injectors
BBK 58mm
Crane Cam 240/244 .595/.595
Magnum 1.6rr's
Comp R Lifters
Pacesetter LT's
Summit X Pipe Kit 3inch
Spec Alum Flywhl
Spec Stage 3 clutch
Cloyes Double Roller

 

425 rwhp.

 

450rwhp+

 

413rwhp with a peak around 5900-6000rpm based on the cubes, valve lift and valve size. That's if you get 100% VE at 6000rpm.

Maybe with a custom cam, ported intake and dead on tune. But i could be wrong.

 

435rwhp/409rwtq

 

well i have Le2 heads and a tiny bit smaller cam and made 417 with an auto. So my guess is around 435rwhp about 6200

 

So you say ~485hp at flywheel with %15 drivetrain loss?? He can't see 500hp ha??

 

Basically. One reason why I don't feel that cubes nessesitate more duration is because the valves will choke off the heads pretty quickly and more duration is just going to kill some of that extra TQ that you are trying to make with the extra cubes.

Bret

 

So what duration would you recommend for optimum performance?

 

depends on a lot of things... lift, valve size, heads etc... no set in stone answer

 

Bret your a PIMP when it comes to this stuff

BTW man (take your time on it, because Lloyd has to send the heads to you still) but you should be getting my super Vic setup within a few days or so.

Bret I said according to thread owner's specs.. (LE3 heads etc..)

 

That would be obvious... buy a LE cam with the heads for the setup. You really didn't think I would post the specs?
