I'm freshening up my 400. I have a Lunati Voodoo 10960701. Advertised 262 - 268 @ 50 219 - 227 lift 484 and 505 on 112 Has anyone ran this cam? Is it a good choice? 69 GS 400 skylark
Not knowing what you want out of the car, or anything else about the car makes it hard to answer that question. Need to know (not a guess) what the true static compression will be. Gearing? Looks like a decent cam, a bit above stock. Power Range 1300-5500 RPM https://www.summitracing.com/parts/lun-10960701 http://www.empirenet.com/pkelley2/DynamicCR.html
Yeah, tell us your goals with the car and engine, as well as what rear gear you have. How aggressive you can go on camshaft really depends on how you want your car to be used.
Its 30 over 400 10.25 comp stock heads and rockers stage1 springs, th400 2500 stall, 3.64 gears, street & strip. Thinking on getting the TA - 290 - 94H. The Lunati Voodoo has aggressive lobes and 505 lift on exhaust, piston to valve issue. Thanks Rob.
I know the stock compression is listed at 10.25:1, but it's very likely that the true compression is closer to 9.5:1 or so. This is because most replacement pistons have a compression height that puts the piston as much as .050" down in the hole. That lowers the static compression. Unless you used custom pistons, or the block was decked for 0 deck, your compression is likely closer to 9.5:1. Did you use the steel shim head gaskets (.020). If not, compression is even lower. That is why I linked this article, http://www.empirenet.com/pkelley2/DynamicCR.html Static compression is one of the factors you need to consider when selecting a cam. That is why you will see a static compression requirement listed in a cam description. Yes, the Lunati cams can have a fast ramp aggressive design. Sometimes the lifter has a hard time following it. The TA 290-94 might put your Dynamic Compression below 7.0 depending on what your true static compression really is.
I’m running the 290/94H in mine, 10:1 .030 over 455 with Stage 1 heads. 2000 stall converter and 2.93s (currently). It sounds healthy and runs bottom 13s. Hoping to go high 12s. Very driveable on the street. Patrick
My experience with the Voodoo cams is that unless you go with much better higher rated valve springs you’ll run into valve float early near or above 4500 rpms.
