Well, you can't beat a 350 with some freshening for decent power and decent gas mileage. A Quadrajet carb will serve you fine once you learn how to properly tune and service it, and they are the best carbs for offroad use. If you want fuel injection, and this is what I'd do if I were going with a 350, find a 87-95 truck with a 350 that is Throttle Body Injected (TBI), and swap that, along with the computer, wiring, and everything else you think will need into your truck. Not sure if you are familiar with TBI, but it's basically the lower half of a big 2 barrel carb with computer controlled fuel injectors instead of a butterfly valve. It's more reliable and tougher for offroading than most stock multipoint injection setups, and gives you more power and runs smoother than a carb, not to mention it will run at any angle. Stock they are like 210hp and 300-330 ft/lbs.
Okay, this is what I am planning for my next truck, some sort of 73-87(91) pickup, hopefully a 3/4 or 1 ton. Find me an old late 60's to later 70's Cadillac with a 472 or 500 Caddy V8 in it. Those things were power houses. They're also relatively unknown, as they were in these big, heavy cars with lots of power options and AC, so the cars soaked up the power and no one thought of the engines as powerhouses. Take that engine out of the Caddy and transplant it into a truck or car that isn't a huge boat with every power option known to man, and you have a <font color=red>STOCK</font color=red> motor that makes 350hp and almost 500 ft/lbs. All had Quadrajets except a few with this weird fuel injection, but you can trash that and bolt on a Quadrajet without to much trouble. Here's a cool fact for you, a 500 makes about 330 ft/lbs at <font color=blue>IDLE!!!!</font color=blue> That's a little more than my 350 TBI makes at like 3600rpm!!![img]/wwwthreads_images/icons/shocked.gif[/img] Oh yeah, did I mention that these motors weigh less than 60lbs more than a SBC? Well, they do. Swap in the Edelbrock Performer aluminum intake and you've dropped it even closer to the weight of a SBC. The only real issues are that these engines need BOP transmissions, so they don't just bolt right up to a Chevy/GMC transmission, and you performance parts and support for these engines isn't nearly as big as most GM motors. The first issue isn't to hard because you can: (1) just use the TH400 that was bolted to it and change the output shaft and bolt your favorite transfer case to it; or (2) buy a $40 or so adapter plate from Jeg's and use whatever Chevy/GMC transmission you want. The second issue is solved by going to Maximum Torque Specialists
and taking a look around there. Performance parts, installation kits, rebuild kits, advice, even stroker kits![img]/wwwthreads_images/icons/cool.gif[/img] All kinds of good stuff on that site.
Either option is a good one in my opinion.[img]/wwwthreads_images/icons/smile.gif[/img]
