Hello,I have just purchased a 1966 Riviera for $400,in not too bad shape.The catch is some freak swapped in a '63 401 and Dynaflow that look like they haven't moved for decades.Pulled carb,intake rusty inside,pulled intake,head ports REALLY rusty inside. My question and dilemma is: would the 401 and dynaflow be worth it?or should I think about swapping in a 430/455? Any input would be really appreciated,thank you. P.S.:the 455 might just be a 1970 out of a '70 Riv!
If there was a good 425 on hand I'd say go with the nailhead since 66 was the last year for them. Otherwise, go with the big block. Seems like since you have so little in the car now it's not worth running up the tab on expensive work on the wrong engine anyway. One man's opinion.
Thanks for the input Mike!Chances are i'll probably go with the 455 because parts are cheaper and easier to find,and because i'd rather not hunt down a "round top" th400,could take years.But do you really think the 455 is a better engine? Thanks
infinitely. Might have a bit of a problem sitting that 455 in where the nailhead once was. You may need 1967 mounting pads and such.
Thanks Yardley but no worries,455 will be coming out of a '70 Riviera,will take motor mounts,transmission,driveshaft,brackets ect. when I pull it. Thanks Again for the advice.
That should work. Take note of any frame measurements you can regarding mount placement. Although, you'll probably have to mock it up yourself with the engine and trans. I install and remove the engine and trans together. Headers, starter, wiring harness and all. One shot. Pull the pulleys off the crank snout and water pump for clearance. As little work on your back under the car as possible. I hate doing tranny's under the car. Bolting it together torque converter and all when on the garage floor is sweet. Not to mention header installation on the engine stand! Good luck!
Sounds Good I agree with the engine/trans combination for pulling.By the way this will be my first ever swap,but I think it will work out.If there's a will there's a way! PS: Went to your site Yardley,lots of good info and one sweet Riviera.
This just came on the Riv Owner's message board today: "I hate to do this but: I have a 1966 Riv parts car for *ahem* sale. What I mean is this: It is available to any one of you who wishes to take it off of my hands. Send me an offer.... It was hit in the front passenger quarter. Lots of glass (windshield cracked) and lots of chrome. All original (as far as I can tell; I'm a chemist, not a mechanic). Engine is 425cc 8cyl. I do not think that the engine or transmission was damaged in the impact (low speed...30 mph). Lots of NICE interior trim (fabric is quite worn on seats, tho...). If I get no responses, I'm keeping the small, nice, intereior bits for myself (and eBay) and selling the rest for scrap. I'd REALLY like to give the engine and transmission (and other parts) to someone who would love and cherish (or at least use) them... Any interested parties or anyone wishing more info send an email to kaedecat@netzero.com Ash"
Mike, Tell me about that message board. I haven't found that one. Can you post a link for it? It's probably something I've overlooked... joined too many clubs at nearly the same time.
