Chevys are the best engines to have for cheap builds based on free or cheap parts
I don't agree.
The reason I got into Buicks and Oldsmobiles in the first place is because I could get entire engines free from the demolition derby guys. The only true advantage that the small block chevy has is the fifth head bolt per cylinder. It doesn't mean as much as you think when it comes to performance potential, but it means one heck of a lot when you smash the radiator and run the engine with no water! LOL! Those chevy small blocks can really take an overheating!! LOL!
Anyway, I routinely buy whole parts cars with running engines for less than 300 bucks, and I have been doing it since I got my first Electra with a 455 for 250 bucks when I was in High School. The cars are still out there, you just have to do a scavenger hunt to get them. I am willing to put in the time and so I do it.
As to the machining comment, I have experience to stand on. I have never taken apart and measured any small block chevy that didn't require machine work according to the spec sheet. Not one. Even low mileage take outs. I did also rebuild two separate 400 small blocks and I didn't machine them; I just honed them and ran the tolerances a little loose. They seem to be fine with that and I was beating the hell out of them anway.
I have shelled apart many Olds/Buick V8's with the intent of doing what was necessary only to find that an overhaul was all that I needed and no machine work. Maybe chevy owners have beat their engines harder or maintained them less, I don't know. It just seems that Buick and Olds engines were assembled better when new and they were never built in Mexico.
I have done a few serious power builds of Olds engines and I didn't spend as much as the chevy guys did after they went to the machine shop. That was my point. I also buy intakes used from swap meets or eBay/craigslist, but I rarely buy new any speed parts other than the cam. I don't like to run those used. Everything else......
