okay ill bite GMCpanel, do you mean that in a positive way or are you saying go with the 292. as Ive said earlier I have no problem using the 235 thru the 302 I want something solid and strong so Iam not coming up short on power I have no doubt I will be hauling 3 or 4 tons in the back of this truck 51 Chevy 6400 with flatbed hoist. will also be looking at power brakes and power steering???
