What is your compression ratio? If your tune is good, the right converter and cam will do wonders with 3.54's.

What do you have the timing set at, initial and total? What do your plugs look like? You can easily change the cam and lifters with the motor in the car without removing the intake. You can always contact Dave over at Hughes Engines and talk to him about your set-up and see what he recommends.



Compression is stock (advertised 10.0:1) with the heads shaved .030". Not sure what actual would be...

I think timing is ~18 initial 35 total (or close to it) on FBO advise.
