My version of a factory parts build 318

the whole idea of their enterprise seemed to be "build a 318 with stock 318 parts and see if we can make 1hp per cube" but that obviously went out the window once they started talking about regrinding a cam and who knows what other nonsense.
How is that nonsense? Why not regrind the cam. It’s a lot cheaper than a new cam! The videos stated right up front that they were going to do a rebuild with replacement pistons. Lightening up parts, grinding away at the head, just removing metal is what they said, right up front.
but then you veer off into crazy town. going and hunting down a set of heads and then having port work as well as machine work done to them along with fresh components? yeah at that point you could probably find a set of decent heads that somebody is offloading for less, or hell, you're damn near to aftermarket alum. head territory.
Paying someone to port and rebuild the head is pricey enough to consider new aluminum heads. Then again, if one could do the work themselves…….. Birds to cheap cheap cheap.
the cam? a low line summit RV cam probably has better specs than a repop 340 cam, and likely would be a split pattern thus working better, for cheaper.
A single pattern vs a dual pattern cam is dependent on how the head flows as to which one will make better power.
Timing events are the important item here. Dual or single pattern.
same with that whole idea of a truck 360 2V intake and carb. why on god's green earth would you go that way when you could scoop up an aftermarket 4bbl intake and a holley/AFB at a swap meet for $150 bucks?
If that’s possible, I’d do that. Dan doesn’t know the carbs are identical except the jetting. The intakes are identical. Year, make & model dependent, the truck could be minus a EGR valve.
conceptually, this is what is commonly called "inversion" or backward thinking. what you are suggesting, while having a good base-- especially the advice on the bottom end, ultimately runs counter intuitive to a build.
Always make a plan and check with the smart guys!
That’s what I do before I leap.
