Default LT-4 UPGRADES

JUST RECENTLY PURCHASED A YELLOW LT-4 AND THOUGHT I WAS IN GOOD SHAPE SINCE MY BROTHER IN LAWS HAD A SALEEN SC281 AND A GRAND SPORT. NOW THEY HAVE UPGRADED TO A 90 ZR-1 AND A 02 ZO6. I NEED A HEAD, CAM AND EXHAUST PACKAGE THAT WILL NET ABOUT ANOTHER 100 REAR WHEEL HP. HAS ANYONE OUT THERE DEALT WITH A COMPANY OR SPEED SHOP THAT OFFERS SOMETHING LIKE THIS? I WANT TO BE TOP DAWG AND CHANGE MY LICENSE PLATE TO READ Z WHAT? SO THEY CAN ASK THEMSELVES THAT QUESTION.

Talk to the guys at MORE Performance if you want a tuner.

For that many rwhp, you would prolly need brand new heads and a big cam

You're in their neck of the woods as well. Getting another 100 RWHP isn't going to be extremely easy however. You are most likely going to have to sacrifice emissions to get there. The two main things that are going to kill your emissions to get there are the exhaust (no cats) and the cam (huge...something like a CC306). Beyond the heads/cam you should put in 4.10 gears, this will give you a nice little extra kick in the rear.

I'm doing good with the mods to my LT4. With a bigger cam than the Hot cam I would be at 400RWHP no problem.

Don't forget to do the gears. Great acceleration increase for the buck. I'd look at 4.09 or 4.10 viper gears.
