I know it's not a 5liter but this is the only part of SN I post in and hey it is a pushrod motor!


I am thinking these numbers are too high, but atleast the graph shows the A/F right in the LS6 sweet spot. Mods are exhaust, intake tube, HP tuner custom tune.

Fun daily driver even if these numbers are inflated. Anyhow just thought I would post it.
 
Aaaah my old disagreeing friend....there is more to a car than all out speed. The Caddi will never have the character and style of a Mustang GT no matter how much faster or comfy it is. Although i like the Caddi, you have to admit they are a bit of a middle aged golfer's car.
 
No worries guys the GT is finally nearing completion, lord knows it has takennearly 3 years to get even close to done. The V and GT both share my garage, as for the middle age thing, well I do have 2 kids and the older is about to start drivers ed!
 
numbers do sound very strong, my buddy yesterday put down 320/320 with a 02 ss maro, 6 speed car with headers and thats it, well an intake but thats all, oh yeah and a 11.0a/f lol my other buddies car put down 295/325 auto car with only a volant intake and a cat back and headers.
 
Or better yet, a 6ish liter 4 cam :drool:
I love the sound of my engine at WOT! With another 100+ cubes it would sound so nice! :nice:
 
my camaro was 340 with a whisper lid, headers, and catback, and underdrives.
I never got it dynoed after the heads were ported and the new cam was installed:(
I bet it would have homed in on the 380-400 mark with a good tune
 
I use Dynojet software almost every day and have yet to figure out a way to fudge numbers other than changing tire pressure or gear choice, and even then it's not by much. Oh, and people need to learn how to print dyno sheets. I heart ls1s.
