You make several good points. I think the Hot Cam is the limit for a good streetable cam. A bit peaky for a heavy car. You can get a little bit better Torque by Advancing the Cam 2*.Originally posted by Lance:
I have gone from a complete stock motor with all the bolt-on goodies minus rockers & springs to a 383 with the Comp 503, thank you KW.
With my new setup, I am now an advocate of the stock motor with the stock cam.
I'm grateful for the Forum and all the members who provided advice regarding my upgrade to a 383. Good thing I listened and researched because anymore of what I have now who have been overkill for the street.
My current setup is on the threshold of being too much for the street. The main problem is traction. Then there piss poor gas mileage and the temptation to get into trouble.
My buddy has a stock motor and I am really encouraging him to stick with it. I told him do the rockers, springs, headers, all the bolt on goodies and wrap it up with a good dyno tune by Herter.
My car with the stock motor was a blast to drive and performed awesome on the hwy. I even impressed a few owners of 993's on a long, fast road trip to Montreal.
Now, my 383 with LE2 heads and the 503 is a new beast that I've put a lot of $1,000's and $1,000's into, that is on the verge of being unstreetable.
I'll be very honest, I wish I had done the rockers & springs and called it a day.
My advice to everybody quick to swap cams, heads and motors be well aware and prepared for all of the extra $, and I mean extra $, you're going to need to BALANCE the setup and get it tuned right.
Now, if your goal is drag racing unlimited, than go for it.
But, for the street, keep it stock with all of the tried & true bolt-on mods and enjoy the extra $ leftover in your pocket.
BTW, just in case if it wasn't clear, I vote for the stock cam.
P.S. Does this counter-culter advice now mean I'm banned from the Forum?
I am kinda like the Silent But Deadly type car. You will get about the same performance from a ZZ3 Cam with 1.6 on the Intake as a Hot Cam. Plus you can get away using the Stock Springs as long as you do not go much over .500 lift. You also will pass Emmission, get the same Mileage, have smooth "Wife" liking performance.
If in fact you want a lot of power to the ground, TurboCharge it. Like having permanent NOS. A lot less expensive then a whole new NA engine.
As far as Cost is concerned the ZZ3 is inexpensive. Believe it or not in the 1/4 mile the ZZ3 will be within a 10th of the Hot Cam.
For now the Stock Cam is fine. With my current Tune and Cecil CO weather my car should be able to hit 13.3'. hot weather 13.90/14.0's
