Ladder bars with it for $1000.00. Thought thats how I'd go. Just need to get the coilovers and the crossmember for it. Appreciate your thoughts on this...confirmed what I was leaning towards. Want to put her in the mid 9's with the bottle this summer.

I get why the cam guys build these thumper cams. A lot of people just want the sound and really dont care how fast it is. Is it my thing? No. But if it make's the car owner happy I'm all for it as It's supporting our hobby.

Just as you could care less of a S10 Truck and trash on it because he dont have Roll Bars.. They could careless for your 9.90 car. To them they're car is just as important to them as your OMG 990 car is to you.

Do I really have to read to you??.Gezzzz!!!.

Or to atleast understand how the numbers affect certain qualities of an engine to pick one close enough to save some money. what would be some good cam numbers for a custom grind for the operation i want? or better yet, help me understand cam design and I might be able to make my own judgements on how to set up my camming. i would rather learn how to fugure all this out than to be told which one to get.
You learning this stuff yourself....now ya talking!.

I don't think you need a custom grind cam.What with all the cam companies the 305 is certainly well covered.

Not to discourage your project 305,but the physics works like this.Torque is the measurement of work done,right??. What follows along with that is the torque curve and at what point is starts to work. What rpm range. Typicality smaller c.i. engines have a higher rpm range where the torque curve begins. That is the laws of physics. Can you fool that some??. Sure,to a degree. The 305's because of the bore size shrouds the intake valve badly too. Yet there are cams out there that certainly will help. My point here is as long as you are walking through that decision door with your expectations given the above...eyes wide open,go for it.

I too suggest before you do a cam choice,you plan out from the T/C to the rear wheel size for a final gear ratio. Given what you have been saying a 3.42 rear end gear which is conservative might be a good trade off gear. Help you alittle on the bottom and still be a decent cruise gear for those 300 mile trips you want to take to a car show.
