I purchased a 1976 C10 with a 427td. It seems to be all stock. I am hoping you can aim me in the right direction on how to go about keeping it drivable, but add a couple of horses. Cam? Intake? Pistons? Maybe there is a page on the forum that answers these questions, I will keep searching in the mean time. I am also in Florida (west coast) Citrus County. Maybe this old man can make a road trip to come shake your hand.
first....welcome to the web site, and since this is an all too common issue,
I'm going to move this to the truck section

ok Id suggest you take a compression test on all 8 cylinders and post the cylinder head and block ,and ideally the intake, casting numbers ,and several pictures would also be great.
and please post your oil pressure at idle and at a 3000 rpm crusise, the transmission and rear gear ratio and tire height,and what your intended goals are,,so we have a good idea of the basics were going too be dealing with.
if the lower block assembly is in good condition you might not have to do too much with that on a basic up-grade.
we would also want too be sure its not a tall deck 366 BIG BLOCK ENGINE
the 427 BBC tall deck engine came in several configs, most were designed for long term durability , not brisk performance,
but they all have the potential to provide that brisk performance if your willing to make the required changes,
and have the bank balance to purchased the parts required,
simply because the basic block is a great starting point.
keep in mind your dealing with a power to weight ratio, you can push a lighter weight truck far easier than a heavy truck, at any given power level.
while a 427 has potential in stock form the smaller port heads and heavy pistons limit the potential, rpms, and the engines ability to breath well.
the tall deck height allows you to install a longer stroke, 4.25" stroke crank, and 6.385" rods and lighter weight pistons and as a result building a 550-600 hp 600 ft lb BBC engine is not all that difficult and yeas if you have the time and cash theres other options
