As the title states I was just wondering if anyone does...
I have a few friends that use to but I have talked to some others that say its stupid and others that think it all depends on setup. So it seems to be up in the air. So what I need to know I guess is there any pro's/con's, what would be needed to make it efficent and so on.

Any info would be nice. and please no douche bag comments, if you feel its a bad idea just say so and explain I dont need some dick head telling me im an idiot for even bringing it up and blah,blah

My buddy shifts at 7k with an ms4 cam and tea heads with stock bottom end. I wouldn't ever shift that high, but I'm in an auto.

@fbody junkie: are those stock 241's? and you havent had any problems... and would I need a big stall converter for this? cause my mods are in sig so would it help any now or should I wait and get a cam first? Also what size tire where you running?

@way2fast: what was your setup?

@sweet99: I have an auto also and so does my 2 buddies that shifted that high. one of my buddies was running a trex the other a ms3. What part about having an auto are you worried about?

The part where it grenades because it's a stock 4l60e lol. I'm guessing you and your friends had built trannies..... When I do my h/c I am going to put in and flt lvl 4 tranny and shift it to about 6500, but still nowhere near 7k. It's also just stupid to shift that high unless you have a BIG cam like ms3 and up

Not sure that a auto needs to be rev'ed that high unless it's set up to be a track car with a big cam. With a stick there's a unwriten rule of thumb that you should shift 800rpm over where you make your peak rpm to have the rpm's drop right back in the power range on the next shift.

idk about my buddy with the trex but probably. as for my buddy with the ms4 no he only had 2.5 ls6 heads and the ms3 then tuned. and me idk got it used so not sure what exactly is done because the person before me wont answer any of messages i send them on facebook (the only way I knew to get ahold of her) but my car already shifts at 6500 I belive and I think my old bone stock ta did also but I could be wrong on that part.

Your going to need a stall converter with a small shift extension to take advantage of the narrow power band. Even with the narrow power band it makes more power in that power band so it needs a small shift extension to stay in that power band.

A tighter converter will have a larger shift extension but a smaller cam will make more torque over a broader range which will help pull the car along.

It's all about what you want the car to do and what you use it for.

A good middle ground must be found.

7k, not me.

For a dedicated track car I could see 7k, but for a DD with a good set of high flow heads and a upper 220s to low 230s cam with all the supporting mods I'd say why, since you won't need to spin it that high to meet your HP/TQ/MPH goals.
IMO, Stock bottom-end 6600rpm rev limit.

@fbodyjunkie: Is there anything you would suggest? I want the most out of what I have. Also I saw in another thread you could spec a custom cam to rival the trex to work better with 243's would that be a good option? Idk my stall specs which sucks. its bigger then stock just not sure how big.

@99bluez28: sounds good, but with my 4:11's and about to be big tire I need a little more then a mild h/c car. plus ill be putting in a bigger converter depending on what I have now. And all the people around me are chicken ***** and wanna race me from high rolls instead of down low where my gears are an advantage. but if you think a 228r cam with 5.3 heads shifting at 6600 would grant me sound numbers and good times/trap speeds... I would love to see any detailed setups for me to look more into.

Most of this is months away unless I find deals I cant pass up.

Ported 853's with old as in 2001 era comp 918s. B1 camshaft that was degreed. Hardened push rods and stock rocker arms. As far as the engine itself. It ha a clean up hone, used Hastings file fit rings on stock postons. The stock rotating assembly was weighed and balanced properly. New bearings and all clearances on all bearings were checked and maintained between .0025-.0030.

Thats pretty much it. Trans was rebuilt by a local guy with all good parts and had a yank tp4400. Put 25k on that setup til I broke a valvespring and dropped a valve on my 3rd trip across the country from Va to San Diego. That sucked.

7400 all day long...
currently a 248/252 .649/.646 112+4
Rest of the Car in the signature...

Putting it all in a Foxbody Mustang....
and going to a bigger cam...
Going to a 252/274 .649/.652 113+4
will probably be shifting around 7800 with this cam...


its all about the internals and how balanced and well setup they are.

I totally overlooked the A4 trans. So with the A4 (w/3600-4k stall) I look for a cam in the low to mid 230s. A TRQ V.2 with a 111lsa, or a 234(xer)/234(xer) with a 110lsa+2 or a 111lsa+3 would be good.

I shift at 6800rpm and run it out the back door at 7300rpm.. Built motor with a 150 shot and a th350

@soundengineer : that is a sick setup, if that just a all out track car?

@99bluez28: yea I have read a few v.2 vs xxx cam threads. It seems to do well up top but alot of people have gone with a 228r or custom.

@odarabla: nice car, when did you start running that high? Like before or after the built motor and tranny swap? Or what... I'm just trying to gauge if it would benefit me or not or just wait till I need to. Trying to destroy people with a 4.11 4l60e exhaust car... Less they see the better

mark21742

Not sure with the new car setup where my shift point is going to be, but fuel cut on my 408 was set at 8,000 rpm and I was shifting at about 7,600-7,700 rpms with my 4l60e, but have a 3 speed manual behind it now and the GTO should be close to 1,000 lbs lighter with big tires and 4.56:1 gears.

I shift at 7k and rev limiter 7200 rpm's. If you are going that high, get at least some rod bolts for the bottom end.
