att 308 guru's, im looking for how to make maximum torque from a holden 308
Im planning my 308 rebuild for the 4x4sandman. My aim is to get maximum possible torque whilst retaining the 5ltr capacity. What im looking at so far are two possible options, but first, the rest of the drive line is;
33in tyres, 3.9 to 1 diff's, gq transfer case, 4l80e trans with a lower 1st and 2nd. probably a low-stall converter.
Most likley option: A pair of Yella Terra high port ali heads on my red 308 with a roller cam, roller rockers, and other quality stuff.
Second option: Big paw holden/chev block with all the above gear. I dunno how they go with their engine numbers and whatnot, im still looking into it.
Just looking for anyones thoughts on all this jazz.
