You caught that,eh;goodonya
Cuz the later ones are the same as 360 but are bushed, whereas my 360core were pressed, and I had several sets.I wanted bushed cuz I planned on taking the engine apart several times for inspection, which I did. Every winter for 5 winters;3 times catching catastrophe in the making. The 4th and 5th times, the engine was fine,so it hasn't been apart again in over 12 years.Maybe it's time again......
The early teener ones were same as 273. I forget what year they switched;69 maybe? Those bushed 318 rods were same casting number as 340 rods. I woulda used the 273 rods but they didn't look like they could take 400/440 ftlbs for very long,nor 7000rpm; you've seen 'em,lol.
But then;have you seen the late hemi rods?
A street engine has a pretty tame life. Lack of traction and speed limits make it so; the engine never works very hard, nor for very long. Really a 360 is overkill. But if you only have one or 1.5 gears to get to 60mph, you need a broad powerband to get there, and that is where more cubes hits the mark with more average power during the run. If you had more gears to get there,you could keep the engine on the pipe,and then you can do with a smaller less-powerful engine. It's always about average power between start and finish..........until the tires give up. After that it hardly matters. That is why, for a streeter, the 60ft is so important.When it's go-time,it's gotta stick.
IMO, a turboed, small-displacement engine with the right combination of parts and a many-speed transmission, could be a powerful force to reckon with,on the street, or on the track.With traction,it would be like a snowmobile; Pop it off the line with little to no tirespin, get on the pipe, and then keep it there. You are sorta building my dream combo, except in my dream I run staged turbos;a big and a little, cuz you know, big ones just blow the tires away,lol.Also in my dream; I run ladder bars and the GVOD as a splitter, so my combo needs just a 1300rpm powerband. So I would start off with just enough power to initiate tirespin. I'd run 4.10s and a 4 speed with the 3.09 low, and the splitter. I'd hit 60 at 5800 in second gear, having used; 1st. 1st-over, and all of second, for a total of 3 ratios. The bigger turbo would need to come in a little later so as not to break traction. I wouldn't care about the power numbers, cuz the combo would be just about the fastest zero to 60 streeter ever on the face of the whole flat earth..........once the turbos were finally figured out. Oh yeah, in my dream, the big turbo is a remote, cuz lag, with the little one up front, would be non-existant. I'd run headers, shorties, cuz,you know; torque is not gonna be an issue. And I'd bolt that little one onto the end of the passenger-side header boxing in the toe-box if necessary, cuz I run alone anyway. Passengers can sit in the back.I'd figure out a way to bypass that little one when the big one gets to doubling the power, cuz you know; that little one on the right side is rapidly becoming a choke.
Actually, in my dream I run a 318 and a plenum on the exhaust, and I split and stage the turboes, off the plenum as necessary to get the job done.In that way, the little one can be buzzing along full-time, always ready to blast off. Yeah it gets complicated, but imagine the pay-off.
Oh yeah, I forgot to mention; in my dream there might be a priority valve somewhere so the teener can bypass the turbos on the start-line; I mean a 4bbl teener with headers and a clutch and a 4.10, and a 3.09 first gear, and a 5800rpm shift, is already a potent force.
But enough about my dream.
Carry on, I've got my eye on you,lol, anxious to see how it all plays out.
