Both are the same brand of tire, Super Swamper TSL. Now this aint drag racing but the Samurai will definately climb a muddy hill (level, no ruts just slick greasy) the Jeep will spin the tires more and will definately accelerate better. But the little light weight Samurai will climb better, hold a line better and not slide in off camber situtions. Weight plays a huge factor in how a car performs. I think in a weight distributing, traction perfect world, a 2300lb 7.9hp per lb car won't accelerate like a 400lb 7.9hp per lb. I have no scientific or mathmatical evidence but I would assume that the hp per lb would have to increase slightly. Maybe a small percent, like 7.9 to 8.1.

i sold my old bbc 572 to some guys that ran it in a samurai they ran it in a mud pit with alot of Nos i would hate to see that run down the track

I have mine geared way down for RockCrawling, I'd like to put a ported rotary in it but the complete lack of lowend torque would suck in a crawling situation. Or a turbo EcoTec... But my 1.3L motors are dirt cheap

yep i did a eco tec were he lean abit to much on it with a blower blocks need a up grade on sleeves but rods and crank look good

We always thought losing 100lbs was equal to 10hp.And that to lose 100lbs was a whole lot cheaper than to build 10hp.
