ls1 guys look in
- Thread starter Syn
- Start date
We can do it at close to 6800 with a stock ls6 intake these days on 6spd cars. I had a A4 F car recently make 477 but it has yet to back it up at the track.I will be trying to find more RPM on the l76 l92 stuff this winter. Being as I finally have enough data to have a meaningful shot at it. As this progress's I plan to post updates but don;t expect anything soon.

it pulled real nice for a sec until t/c kicked in, but i can't wait
never drove a car with a stall before either.
also i seen alot of people talking about going speed density, is it really worth the switch?
S/D isn;t really needed. The extra few HP you might get is offset by breaking the operating system in the PCM.

a few other things i was thinking about today
what to do for a clutch, i read the ls7 clutch is junk from alot of people
figured sean you'd have some input on this. also any input on a lightweight flywheel?
i also tried finding a complete ls2 timing chain kit that has the sprokets but all i've been able to find is the chain, cloyes has a kit that my friend can get from his work (autozone) suppose to be oem

can't use the ls2 cam gear. Its a one bolt unit.
depends one what you want to spend on a clutch. Alot of people don't like Spec's but my stage III x-pad has taken more abuse than anyone ever thought it would. I wouldn't use a lightweight flywheel unless the car is very light, very hih geared or is only road raced

a few more questions
do the fbody ls1's use a windage tray like the vette's?
a mod on camaroz28 said i can get all the parts to rebuild my t56 to make it almost bullet proof for around 450 but i am not seeing that lol, anyone have a good site to get some good deals
then i was looking at some valley covers, one has the 2 holes for the knock sensor and one doesn't, why can't i put my knock sensors in the stock place like the ls1's on my iron block if i have the 2 fittings on my block

I can vouch for that, I learned how to do a cam on a LSx on a 06 GTO which had 3 holes. One was a dowel correct and the other two small bolts

l92 heads
the biggest hold back about the l92 heads is the damn intake. even the intakes for the cathedral ports suck....but i believe there is the most gained by porting on the exhaust side for the l92 heads running stock l76 intakes. accordin to the flow bench the l92 heads flow the best with the gm performance single plane carb style intake...compression..well in my opinion should be good up to bout 11-11.5:1 depending on camshaft. for pump gas. but guys the damn chambers are about 70cc so to get the compression be prepared to mill them babies and run a thin ass gasket on stock shorts. but then becareful because the damn plastics intake well they start fittin pretty tight and becareful of port and bolts alignment. then thinnest i have ran is milled .045 and runnin a .040 gasket and the intake was pretty snug..prolly could of got away with a little more but things are ganna start gettin tight. the mad scientist and myself try to keep tabs on these things. i know we have made over 500 rwhp with livernois heads n cams stock shorts and none of them had all them bolts ons electric water pumps,pulleys,none of that stuff just good exhaust system and a good tune...on vettes and f-body's.... even though i build em still just don't care much for them damn mod motors....lsx till the end...lmao....

The intake may not be a big deal. I am going to run some camshafts with another company this winter and see how they do. If we get lucky " I hope so" the R&D I have been putting into developing camshafts for these plenum ram plastic intakes should net results with the l76 intake.
Hold tight till spring. I think there is more to come.

I did 472rwhp locked (4L60E) with an ARE 422ci iron block in 2001, with 244/244/112 cam and ported LS6 heads, through an LS6 intake, with a Yank PT4400 converter, 9" and on slicks. It was 12.2:1 and ran fine on pump gas though we only ran 25 degrees of timing. I never ran enough converter in the car to optimize it for motor, went 11.02@123 on a 1.5 @ 3600 raceweight.
My 2000 Z/28 runs a 240/244 cam in an 11:1 348ci, made around 425rwhp with an 8" converter, 9" and slicks. It drives just fine no surging. I'm running 28 degrees of timing on motor. Went [email protected] a few weeks with full tank of gas so like 3350-3400 raceweight on a 1.48.
I think the 25_/25_ duration cams are huge personally.
