Can a small block be built to pull like a big block? If so; which one, 383, 350, 406, etc.? Will it be less durable than a big block?

Yes you can,everthing you do to a race car engine is almost opposite truck engines live off of torque more than horsepower.Like a diesel they dont turn any rpm to pull.The more cubes you have the easier it is because a long stroke helps,low compression,small valves,and a heavy flywheel all make for a good pulling engine My own opinion would be 383 or 406 Just my 2cents....towman

i would build a 383 with alot of torque. it will get the best gas milage and pull as good as a 406 without any heating problems and a 383 is cheaper to build than a 406.

Ive got a 1 ton chevy wrecker with a dish piston 406 441 heads small cam , stealth intake and edelbrock 600 (i think) Its a real stump puller I have no heating problems and If you drive it right it will get 12to13 miles to the gallon and its a very heavy truck Im guessing around 11,000lbs. And I wouldnt change a thing.Just my opinion....towman
