Yep. Doug, I don't know the specs on a 427R motor, compression ratio and the like, but if you post them the gallery here will recommend a cam that gives you more low end torque for improved drivability. Now, it's never going to be a stroked FE, but it will definitely let you enjoy the driving that you're actually doing. I don't know with a small block SPF if you can pop a new cam in without pulling the engine or not, but it's still a one day job for a decent mechanic... and a two day job for the rest of us.

Thanks. I will look that up in the manual. One thing I will have to careful of is not voiding the factory rousch 2 year warranty. I was als thinking of giving them a call for their feedback as well.

I have one for almost 2 years now. It doesn't like low rpms for local driving...below 2k. It reminds me of old time race engines. I set the idle a little higher around 1k and keep the operating rpms for simple cruising around town between 2-3k. If you do that, you will be fine. Its quite impressive when you push it to those higher rpms. Bottom line.....leave the cam and motor alone.

Thanks Fred and I tend to agree with you.
