I hope it is okay to resurrect this old thread. I am looking to rebuild the original 350 engine in my 1972 Blazer 4WD and want it to look all original when done. I prefer to use the heads, intake, carb, exhaust manifolds and valve covers as original. I know this will leave me with limited options to improve performance. I want to increase horsepower and maintain good torque. Current spec is 175HP and 290 lb-ft torque at 2400 RPM. What is the best I can hope for keeping it like I want? I'm thinking all I can do is look at the cam, lifters and pistons.
How did you build yours? Any thoughts on what I should be thinking? I appreciate any help.
