100% street driven stock LS1 block combo's for swap into 79 camaro!
number 1.
custom comp cam 224/224 .565/.565 110lsa 106icl (yes its fine on the street, and made 400/400 stock heads)
Crane Gold Quick-Lift rockers 1.80
stage 2 LS6 heads (10.7 CR)
FAST 90/90
custom 32" 1 3/4" headers with HVMC
3" X-pipe out the back (79 camaro had duals)

number 2.
same as above but...
LS6 intake
same headers, 2.5" X-pipe out the back

Opinions. Cam is too far advanced to make good power at all rpm. Consider having it ground at 110ICL (no advance). You will make 10-15 more rwhp and still have strong low end torque.

The FAST 90/90 is definitely the way to go. I gained more from a ported FAST 90/90 than I did with headers (27 vs 22 rwhp gain).

Don't do the Crane rockers. Too many people are having issues with them. Results are all over the place. Some good, some bad. You'll have fewer headaches with the stock rockers.

thanks Patrick... btw... your setup makes me

the cam on the 106icl on stock heads (full bolt on though) makes 380#'s and 360hp by 2800... peak HP of 400 is at 5900 and carries too 6500 before dropping off.

I dont want to shift past 6500 on stock long block, so that is perfect for me.
but I will keep that in consideration though, thank you for the thought!

it wont be a track car. it will wont see track. just a street driven G-Machine

oh, and what about the exhaust ?

Headers with HVMC are a solid investment. I'd do dual 3" to the x-pipe, then neck down and do dual 2 1/2" the rest of the way back.

I still have to highly recommend you consider grinding that cam at 110ICL. At 106ICL, your intake closing point is 38 degrees ABDC (at .050"). Way too early IMO. You'll make better power EVERYWHERE with the 110ICL. Your intake closing point will be 42 degrees and your overlap will happen right at top dead center (which will allow you to make very well rounded power). Like I said, 106 ICL you'll make peak power at around 5800-5900. With 110 ICL, you'll make peak power closer to 6100 and will make 10-15 more rwhp in the process (while still maintaining the power down low of the 106 ICL cam).

i would increase the compression ratio to 11.5:1

EDIT: messed up.

below please!

so the same cam ground on a 110lsa and 110icl ?
will it still make the trq (380 or so #'s at 2800)
thats what I really car about. I want the most trq at really low RPM where I drive 90% of the time?
thanks

It will make more torque (total area under the curve). As a general rule of thumb, you advance a cam that's too big and you retard a cam that's too small. A 224 is not too big and not too small. You don't want to advance this cam, especially with a 110LSA.

oh okay, I actually think im understanding that! im learning, cool!!
so the same same 224/224 .565/.565 cam on a 110lsa and a 110icl will actually produce more trq from driving range 2500-5000 AND make more hp than a 106icl ???
is that what im gathering here?

thank you so much Patrick!!

seadoo

Patrick? u still in here?

You've got the right idea now.

seadoo

you are the man!!
wish u lived in FL

so... Patrick.... one more bothersome question (sorry just trying to learn this stuff)
so we have now set a 224 with a 110lsa and 110icl...
what about lift. speed, inc told me that I will gain power and about 15#'s of trq going to the XE-R lobes (.581 lift) from the XE but it will begin to buck on me at low rpm.
will only a .581 lift hurt drive ability that much??

seadoo

okay, update on combo... thanks patrick G

same as mentioned but 224/224 .581 110lsa 110icl
and ls6 intake for now... then the fast when the $ comes in
