it's not what cam will work with your engine, it's what you want out of your engine. For my street car I went with the ZZ4 cam since it's good with low end torque and the power curve is what I want in my car. For the engine we built for the race car we balanced the engine for 6000 rpm and used a cam worked from 4500 to 6500 since it was governed by a 6300 chip
I get what your saying....it's just very hard due to the zillions of choices. My range is idle to 5500, pretty broad lol
if you were closer I'd let you try out my car, it's a 355 with vortec heads and the ZZ4 roller cam. It pulls from the start and on the highway it pulls. I was doing 50 in 4th last weekend and it took no time to get it to 105..then I shifted into 5th and turned into a law-abiding citizen again. 8)
Oh man!! What intake and carb do you have? Before I choose a cam I like to have a carb picked out an possibly a steetable stall for my 700r4
I have the edelbrock performer rpm ram air with a quadrajet of course. The carb is built by a local guy who is known for his q-jets. The tires will spin all the way thru 1st and that's with 3.08 posi and the distributor rev limiter is set at 5500. The nice thing is I only have about $2,000 in this engine
Sounds like a nice cruiser setup you got there. I have a brand new set of comp 981-16 springs. I can't find a whole lot on these but I wonder how much lift these can take and if they would have the right spring pressure for the vortecs.
Here's a link I found to the info on the springs.http://www.jegs.com/i/Comp+Cams/249/981-16/10002/-1
Looks like they would work on Vortecs, but I wouldn't use them with a roller set-up because they have no where near enough seat pressure. You need something in the 150-160 lbs range at least to keep it from valve floating early.

Well the zz4 springs say 101 lbs at installed height so wtf? I see what your saying, it's all confusing since nothing works perfect and you gotta find a system with the LEAST amount of down sides.....I'll probly go with the zz4 spring and retainers and a lunati voodoo cam.
I have no valve float with the roller cam and the ZZ4 springs. The ZZ4 springs were designed to be used with the roller cam in a performance engine
