After a ton of research and reading all the reasons why I should drop in a 351 instead of building a 347... I am proceeding with a 347 stroker build anyway!!
My reasons- I already have an anemic 5.0efi in the truck, so most of what I need is there. I don't have headers, but the serp setup, harness and all the other accessories are in good shape- (and would likely have worked on a 351 as well). Before you bash me- it's my money and I can spend it how I want %) and I wanted to build this motor (it’s been a while). I just thought I would post up the progress here and my current costs for anyone interested. No need to post if you just want to say why to go 351… save that for someone else’s thread!
My truck’s basic specs:
1975 w/ 5.0, C4 with a B&M shift kit.
4.5" suspension & 3" body lift
HP D44 narrowed front with 4.56 gears & ARB locker.
Big bearing 9” rear with 4.56 & track lok
4 wheel disks with Hydroboost.
37” Toyo MTs
Lots of other stuff...
My goal is to have it complete by Super Celebration 2013. I want a driveable motor with good torque to push the 37s. Good sound and enough power to get out of its own way… maybe a little more.
I started by picking up a complete (minus front accessories) 1996 Ford Explorer 5.0 out of a running truck with right at 100k on it. Although it had an obvious oil leak from the oil pan for a long time- the motor looked OK on the outside. Upon teardown, I could have thrown new gaskets on this motor and dropped it in. It would likely have added 50Hp+ over the one that is in the Bronco now and lasted forever. BUT- I am ignorant, a glutton for punishment and want to clean up the entire engine bay while I am at it. Picking up another block will let me drive the truck until I need to pull the old motor. I actually started this process several months ago.
After motor teardown and cleaning, I notched the cylinders and tapped the front oil galleys for threaded plugs instead of press in. Dropped the block off and picked it up 4 days later.
I am still working out what direction for heads (GT40 irons or aluminum aftermarket) and cam.
Input always welcome!!

Anyhow I'd pick the heads you want that will give you the comp ratio you want. Although I would say that iron gt40's are probably not the best choice here. There about bottom of the line for even a stock 302 much less a stroker.
