Tires/HP/ and lowering! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello All! I am back from Iraq and started a frame off for my 68 c10, I am going to be running a 454 big block, what would you recommend for the lowering ratio? I am wanting to go with 3/5, will it change with the weight of the motor?
also I am going to be pushing around 600 horse power, give or take and are concerned with catching traction when really getting on it, I have the chris alston 4 link now trying to get a good tire size to grab. My uncle was thinking a 280 or 285 in the rear or do you think that is too big? I am not tubbing Just stock wheel wells I want something that wont rub and want the fenders to just cover the tires Just like Sactojims if you guys have seen his. My truck is going to be used only for weekends and toying around, Thanks for your time and knowlege.

do a 4/6 and a 295 on a 10" rim Nitto Proxes II's grab really well.

IMHO don't waste your time building that much hp if you are only going to be using a 280 tire, save your cash.
if you wanna run 600hp (possibly more) with the torque of a big block, I would tub it if you plan on lowering it and can't have the rubber sticking past the fenders.
it will never hook, look at other vehicles as an example... lets say a corvette, those things have 345's or something near with a rwhp a little over 600, and they have an almost perfect front to rear weight ratio, AND they have computer controlled launch programs to allow it to actually utilize most of the hp.

hmm... 280 too big? what were you thinking of using?
