I has wondering what mounts you guys are runing on the V8 57's front moter mounts or the side moter mounts?
My '57 GMC V8 (probably not what you are asking about) uses a single mount in the front and two bellhousing mounts.
The 55-59 chevys that came from the factory with the V8 used the front mounts. If your using a manual transmission than I'd use the front mounts. However If your going to go with an automatic you should use a crossmember and the side mounts. Chris
I just don't know if they will take 450hp pounding on that style of mount. Maybe it will i don't know.
Matt, I run the front mounts and i have a 500 horse 383.Don't forget the main load is on the tranny mounts.Hope my 2 cents helps you out.But if you have a GMC i would run the side because the GMC's use a "U" front motor mount and is not to stable.
i have two 58's one suburban the other stepside short wheel base the pickup uses side mounts because the 396 aka rat motor is about 2 inches longer than a small block !!!! with a big block your stock throttle linkage wont work either and you guessed it custom headers to clear steering box !!!!
