If you are wanting to stay NA (all motor) then you will never have enough power to worry about blowing it. These motors are good for almost 500 at the wheels with the "safe point" in the 450 range.

As for mods, trick flow makes the best heads and comp 270 cams are one of the best on the market for stock GTs. You can also upgrade your intake manifold to the edlebrock one, and get a bigger throttle body and plenum. Then you have full exhaust and gears.

But just my 2cents, if you did all that above you would have $5000+ and only put down 370-380hp. If you spent $3000 on a cheap supercharger kit you will have less invested and be capable of pushing the motor to its limits and beyond.

The teksid block can handle waay more than 500 hp. It will handle 1500+ without block mods. Pending what the engine came out of it could have a forged crank or not. Run your block numbers and make sure of what you got.

Teksid block does not mean DOHC. Thousands of people use teksid blocks for 2V builds every day.

This. If your car has the factor motor you don't have a DOHC and you don't have a teksid block. Post a pic of the engine bay and I will tell you what you have

Nah man. If it is a DOHC then you don't have a GT. And if it's a real GT then you either don't have a DOHC or it's not factory.

Go FI. About 8 psi of boost is a good start. Cams and heads headers mid pipe and cat back. Cold air kit tuner maybe a little nos. B heads are great for FI. Just run the block numbers and make sure of what you have.

It also says GT. So one way or another this guy is wrong.

---------- Post added at 11:05 PM ---------- Previous post was at 11:03 PM ----------

People say DOHC instead of SOHC all the time. It's alot harder to mess up GT since it says it on the side of the car

Still say he needs to run the block numbers and see what he has...
