off topic is never a problem matey, though perhaps the moderators view it differently. i'd kind of been hedging on getting a bite from that statement.
you own my best mates fathers (essentially a second father to me i guess) other dream car. the split windows never quite did it for me as i'm more a 68 convertible kinda guy, and the 427 option from the 66 onwards models over the small block weighs heavy though face it, you could bolt whatever you wanted in after the fact, but he loves em. his other dream car ended up his reality as he bought a 55 2 door post (pillared we'd call them) shoebox in about 94. theres a 350/th350 combo in there at present but he's building a 400 crank 383 stroker with trickflow twisted wedge heads, holley pro-jection, and a turbo700 up its butt with the obligatory 9 inch in place of the factory diff thats still there. his previous baby was a factory 350/th400 Holden HQ caprice that he sold off to buy the 55. but even he admits that they came a long way, and theres aspects of them that really aren't great. your 327 is a far cry from the 2 barrel 265 and the same again from the current ls2/3 but theres architecture there that stems from 54 years of people tinkering and often not with a clean sheet. the push in rocker studs of the early motors went the way of the dodo, the crossram on the early camaro's was a pretty distant setup from the more mundane engines intakes, the port and chamber layout was not carried over to the late stuff and the number of idiots locally who identify their new commodores engine with that of the 307/327/350 knocked out in our local monaro's in the 68-74 heyday of the smallblock here as a locally offered motor. yes they can be made to really hammer and there were specialties that went hard from factorylike the lt1/fuellie models/z28/etc, but it only takes one ride in a mid sixties bel-air with a 283 struggling against the weight, and the joy of a powerglide to realize that they weren't all performance motors. i stand by my comment that they were more a development than they ever were a masterpiece.
porsche may have started off with the beetles donk (which he designed) and stuck with the boxer layout, but the lineage between an early 356, the later ohc, the early, mid, late, and current 911's and the big bangers like their 917 and 956's has some very big steps in the process. you can't readily pluck components from your 55 porsche and interchange them with your late 90's models smog engine like you can with the small block.
