Engine Mods For 1LE?

1. Remember orange crush and the cam and heads that caused his engine to blow.

People here laugh at me to wanting the Chevy performance dynamic duo which yield only 40hp and a conceivably high price. But call me risk averse i trust the red bow tie group who focus on

Has anyone on this forum purchased the dynamic duo heads/cam setup? I am researching cams because I plan to have one put in in the near future. I have been hearing tons of good things about the quality and durability of cam motion, but like you, I prefer to go OEM if I have the opportunity.

Honestly I know of no one who has here on the forums or anywhere else for that matter. I'm an outlier for my interest in it. And, frankly, they may not be CARB legal here in Cali, hence my going with JBA shorties; I have the sticker. I'd hope there are some CARB approved cam and heads but who knows. May I ride the coattails of your research?

I just can't believe not a single person on this entire forum hasn't picked up that package. I remember reading on here that the cam was just a stock ls7 cam?? Not sure how accurate that is.

Will a cam swap affect emissions? The cam on my current Mustang would normally cause me to fail. It sounds great but it is a pain in the ass to inspect the car. Long tubes can also fail a car around here. :(

Heads and Cam are a great option if you are looking to tear down your engine and put it back together over a weekend......

Or you can spend 6 hours installing a supercharger and get more Emissions legal HP and TQ per dollar, with room to grow.

The S/C is great but it ruins the balance of a 1LE and adds weight. Heads/Cam/Intake with all the other bolt ons gets you well over 500/475 and keeps all of the balance intact. Concentrate on suspension work too...

If I absolutely needed so much power for it to be borderline ridiculous I would do a low mount TT like an AGP kit. It puts the turbos back towards the firewall and low that keeps the weight gain as neutral as possible. With minimal boost they make 750+...

In all honesty though you have to guess with bolt on mods you will have around 500/490. I'm putting down 435/425 right now. I can obliterate my 295's out back at will and it takes concentration to maximize acceleration through second gear without converting to smoke. With heads and cam and one of the upcoming manifolds I expect to at least add 100/100 to the tires, that puts me at 625 - 650 FWHP. I will have hell driving it like that and still be fast. Michelin will love me though... LoL

At the end of the day 90% of us will drive the car 98% of the time on the street...making it a street car in my opinion. I would MUCH rather have my car running the way I enjoy it 98% of the time than 2% of the time.

Lets take the 52/48 weight distribution and ASSUME they measured it wet (full of oil, coolant, and fuel). The supercharger ( I am using the SLP ) netted an additional 65.60 lbs to the front (after I weighed the parts removed), and I have YET to feel or find that in the performance of the car. I will have the car on a Longacre scale in the next few weeks to confirm the actual change in bias.

At the end of the day it could be said that any power adder ruins the balance of the car, power delivery itself has a big effect on driveability.

With that being said, I know of many 1LE's with superchargers that run better at the track than they did Naturally Aspirated. To each his own for sure, a less invasive power adder was my choice and I will never look back.

I'm part of the 10% and you'd be surprised how it handles on some of these on and off ramps in FL.

I do get your point though...

I am sure there will come a point (that magic one that happens to us all) where I will out drive the factory parts. When that time comes, I am sure I will reach out to folks like Justice Pete to get it back in line.

Good Chatting with you, I looked at your build thread, well done!

I'm in conversations with Pete right now... LoL

Thank you...
