Carbureted LSX forum - dyno day

so yesterday I had my 72 el Camino on the dyno.

it is a completly stock 2000 5.3 lm7, whit the rpm manifold Edi. 600cfm. pacesetter lt. for F-body, and the 6010 set on 32'

it made:
271hp at 5071rpm
425nm at 2916

now it is running a bit rich. but i think it is fair good.

Nice, imagine ported heads and a cam. My 6.0 made 292 rwhp through a 4l80 and 14 bolt, stock efi with exhaust and k&n.

the cam is the next step, but i have to keap the low end power, it is a DD in the sommer and has 2.72 in the rearend. so no high rpm cam

old man cam might be just right then ;)

link?

The TR220R grinds may be what you need, they will keep torque but add allot of power and sound fantastic, search for it on youtube to get a idea of sound.

Wow I hope my AL 5.3 makes a lil better power bc I have a 4 speed manual...but a cam will def wake that sucker up paired with appropriate converter...

it is at the motor. so it will make the same if i put a manuel in it.
but i am happy, it makes 285hp and 440nm in stock fuel injectet form. and if i had opend the hood and not had it so hot after 1 houre off cruising it had made more.
so cam and cold air intake will be next

You would gain from simply swapping to 243 or 799 castings as well. 3-400$.

zone:

your right, but i live in Denmark så ther is no spare motors ore heads

eBay or find a seller here that will ship!

what will the gain be from the head swap?

Head and cam swap will net at least 50hp depending on cam and you could

Head and cam swap will net at least 50hp depending on cam and you could Probably do it for $1000 in parts...I'm not sure on shipping though

what will the gain be from the head swap?

A 243 or 799 head swap(same head different casting number) would gain 20-30 HP, If you did a baby cam and the heads you would see 60 or so gain.
