Vacuum is a partial reflection of compression, but otherwise it really does not matter at all how much you are making. I dont care if you are pulling 32 inches at a 650 idle...it doesnt matter that much. I never really worry about vacuum, I check compression anyway. If compression is over 105 then I consider it a pretty healthy motor. If it is over 115 then I consider it damn strong. I have never measured more than 125, even in a "new housing, new parts" motor, and I have measured 120-125 in a "used housing, used part" motor in which the housings were very lightly worn and the engine had a few thousand miles on it.
And yes, tuning/install/setup plays a big part in which engines blow. BUT, people are just as likely to botch the install/tune on a 5000 dollar pineapple motor as they are a 1000 dollar one that I build. Which one would you rather them screw up? I can link you to 2 or 3 posts within the last couple of months, of users who say they had this expensive engine "built right with all new parts, built by one of the best" that is blown/defective within the first couple of years. Now they do not know what to do, as they sunk all the money into that one "do it once, do it right" engine.
Not only because I build budget setups, but as someone who works on his own cars and hundreds of other people's, I say "build it decent, put your money into the car and not the engine block, and treat it as disposable so that if in 2-4 years you need another, you won't be that bummed out". After all, I can build 2 or 3 strong blocks for what many companies charge for 1 "new housing, new parts" motor. Honestly my setups tend to last about as long, or longer in some cases.
But hey...for those of you playing with monopoly money and can afford the best of everything, well that is why there are these high dollar builders here to serve your wishes. Somebody has to keep them in business, I guess. Better them than me.
