It’s all fun til the rabbit gets the gun.
I have a 1970 Belvedere 318 and a 904. I'd like to swap the motor for a 383 or 440. This is a street car, not a race car. Will the BB bolt to the small block 904? Any issues or mods?
I forgot to ask you WHY you want to do this upgrade? I mean, I'd do it but I'm not the guy to be asking because I just want to go fast....really fast....then put nitrous on top of that.....and still trying to figure a way to convert it to alcohol so I can put a blower on it too.....it's like a disease.
I hear you bruzilla. Sonny isn't trying to run mid-9's in the quarter.... and keeping in mind the "macho-cool-factor" you're talking about....what about a 360 six-pack?....with an air grabber hood?
Guess I did all of mine wrong....wait, my right foot is shaped like a brick!A BB built right will surprise you on the mpg as well.

My first race only car was a 68 road runner that ran 10.68 with a tunnel ram and two 750's on top, it would make 1 pass on a gallon and run out on the return road and then coast a couple hundred feet and almost make it into my pit area. It really slowed down making a turn....dang spool really killed mileage lolFunny Cranky... BB's are also excellent for GPM...gallons per mile...preferably 1/4 mile at time.
Don't need to burn alcohol to be blown,,,just drink itYour idea to put a big block in the Belvedere is very do-able, but it requires a whole bunch of parts & somewhat advanced mechanical knowledge OR a huge pile of cash. Another option to consider might be a 360 small block OR upgrade your 318 with some of the newer "magnum" 5.2L (318) parts. 273's (small) and 340's (expensive) also will bolt up. All of these small blocks are relatively easy bolt-in engines that can use your existing transmission/driveshaft/rear end, etc.
