they could make it a requirment that if running the LS1 pcm, the rev limiter must be set at a certain RPM. 7000rpm would be a good mark, right where the LT1 pcm starts to die

We *could* make that requirement, but there's no way to enforce it when a car is going down the track. If you don't fit in Extreme Street because of a PCM swap, you can still run Bracket and/or Index if you're not quick enough for Modified.

My opti has been to 6800-7000 MANY times. The ONLY reason I would do this swap was for the 1000 rpm and the 4.88 gear I could utilize with the extra rpm. The only other reason I could think is easier tuning.
The facory LT1 ecm is very capable of handling 650 hp NA.
I am more interested in the minimum weights, we aint racing coupe Mustangs...I mean come on 3075 lbs min weight in Mod. Geez do I have to have doors and front clip?

Flushing money in my opinion if this is the only reason to do it.

Flushing money down the toilet? Blowing up opti's, towing bills, and spending money on tuner's who dont know what they are doing and/or crap software is flushing money down the toilet. Just because MSDOS can write me a document doesnt mean i dont want to run windows. Im not stuck in the past. And just like MS-DOS, there is no good documentation or support for it anymore. Why would i want to screw around with that when i already have the experience in HPTuners to tune an engine in 20 minutes? And if i cant i have a support forum and 5+ personal friends ready to help me with it, none of which i have with OBD1. Manually calculating something that can be done automatically doesn't impress anyone.

The factory ECM is capable of more than 650 to the wheel. That doesn't make it a good solution for my STREET car where i want reliability. If horsepower was the only metric people ever considered, we would all still be running around with carburetors!

I just dont see the reasoning when DOS will do the job and go JUST as quick down the track. But hey to each his own I guess. I am all about making the car faster.If I spend money to change something its gonna be to make more power and go quicker. If you are gonna leave the rev limiter at 7000 and not change the cam and gear to take advantage of the deal you just spent money on I dont see the point.
But hey, fly your own boat I guess.

There is a broad range of cars wanting to run Mod....cars like yours that weigh 36-3700 lbs...and some SE cars that weigh less than 3000 lbs (they will have to add weight and most will have less power than you.)
The reason for the weight breaks are to bring in more cars. Vettes, Stockers.....etc but at the same time keep them limited to help level the playing field with the heavier cars. It will all work out.

I understand, but damn 3075lbs? I put a post earlier about exhaust but was not answered. No exhaust? Open headers in Mod NA?
I could GUT my car, spend $2500 on lightweight parts and not make that weight.
I could get to 3450 with no exhaust, one kirkey seat, no A/C evap, no carpet.
Who the hell weighs 3075 ready to race anyway in the LT1 world? DO I need to put my combo into a coupe stang and come race? Its a all LTx race correct? I can spend $2500 on a roller and make the weight.
Guess I may have to call up my lightweight driver mod LMAO!

Your right, I'll have to carry some ballast to make that.
I just noticed I also have a race the weekend before (at Topeka), I knew I had one the weekend after. Don't know that I'll have time to switch everything back and forth.

I weighed my car a few months ago and i was 3400 with me in it and half a tank of fuel.... I was hoping to drop that down to 3200 using a fiberglass hatch, lexan rear window and lexan windshield in the next few months....
and man i can't believe Ed is gonna hafta add ballast to make weight.... i gotta see what's taken out of that thing...
Ed you got fiberglass doors and lexan at all 4 corners??? what class you gonna run??? Outlaw i'd imagine????

I had almost 260 lbs of ballast in my car to run last years race (including the weight box). I still have all the interior parts like carpet, panels, headliner, stock seats, etc. I also have all stock body panels and a full cage. So, yes you can get an LT1 down to 3200 lbs without spending your life savings on light weight parts.

Factory windows, fenders, hood, rear hatch, etc. I'm not allowed to change any of that stuff in NHRA & IHRA Super stock. With no alternator (I run it with one), one battery (I use two) and nothing in the weight box it's 2845 without me in it. Taking all the TA crap off and making it a regular Firebird would loose about 40lbs more, I'm told. Don't know that for sure, but other guys I race tell me that. Most everybody with one of these is lighter than mine, but nobody else runs their's as a Trans AM. Most everybody else's was built from a body in white, or completely stripped, cleaned and painted on a rotiserie <SP?>, mine still has the original factory paint inside and out. One young man asked me, at an IHRA race, "Who did your paint?". I said "GM'. If I can make it I'll run Modified NA.
