Yea, that is pretty good power for that little Cam..

 

I'm assuming from your sig that you are not running the stock LQ4 pistons. With 59CC heads you would only be about 10.5:1 CR and not the 11.1:1 you have listed. Nice numbers either way.

I am setting up a LQ4 with PRC5.3 heads milled .02 (59cc) with a cam 224/236 609/607 111+2 and LS6 intake. I am hoping for the magic 400rwhp number

 

^^I don't see why that wouldn't hit that mark..

 

That is a pretty quick setup, 6.77 is dooable. Mine was carbed with a 212 224 cam stock 317s and stock lq9 shortblock with good bolts. @ 3420# i went 7.40s on the motor, 6.60s on a 150 shot, and 6.30s on a 200 shot. The 200 shot = 1.38 60' and on motor it was a 1.60-5 60'. 110 was the best mph, it fell off a little on the big end. These stock bottom 6.0s have potential to run pretty quick.

 

Heath,

Did you true-up the rods after the bolt installation? Im installing some ARP2000 in the motor I bought from you and was curious.

 

yeah it hits like a beast, i think some of it is due to the trq it makes off the line too, most big cams dont have any bottom end, my car makes its times in the first half of the track,

 

That's kinda how mine feels like, it gets off the line and down the first 1000ft hard, then kinda fades out..

 

I would say that 360 on a stock cam is possible with a m6

I had 349RWHP with cats on, no underpulley yet, the LS7 clutch(extra rotational weight) and heavy 315 tires on 17 inch rims.

Take the cats off, toss on underpulley, go to a lighter LS1 type clutch, ditch the rims for lighter stockers and maybe a electric pump and easily see those numbers.

Now for a cam car to hit 10's? Mild is a 22x cam as I recall and those usually produce low 12's or 11's if done just right, can't picture the words mild, 10's + gas mileage all in the same sentence unless power adder is also added.
