Ok Let me tell you my setup ..

306 w/ SRP Pistons stock crank and rods
Strike force Alum. heads 200CC 2.05/ 1.6
F- Cam
1.6 RR
ARP bolts - and a girdle

As of right now im running a 70MM TB with Trickflow Street intake..
I was considering the Track heat .. with a bigger TB?? Or the Trickflow Box setup... Anyone upgraded to these? Big diff? .. Will it be worth upgrading for Boost...

I wanna hit 12s all motor w/out slicks
I ran 13.2 @107 as of right now-- Full weight GT

You don't need to change the manifold for 12's.

Put a drag radial on it. What gears do you have?

He's got a point there. Whatever you do, a box-type intake w/ a 306 will make you hate your car on the street. Keep away from that one unless it's a weekend car w/ a lot of gear.

You have the MPH now, your problem is in your suspension/traction.

Yeah, pretty much...maybe little higher depending on the rest of the combination. Point is, the manifold you have will do its job just fine across the RPM range you're working in.

When I put the Comp Cams upper on my original 302 with a Cobra lower, the power didn't hit until 3,500rpm. Below that the car was a dog. Above that it was a raped ape.

I was running 3.27 gears at the time, and the sound system adds a couple of hundred lbs to the car.

With the same gears, weight, and upper manifold on a 408w and Lightning lower (basically the same as the 302 cobra), the car is much more drivable.

My thoughts,
jason

A bigger motor is also a good fix to the torque problem .
