I searched around the internet for awhile and was unable to get a clear answere. Is it necessary to weld reinforcement plates anywhere on the frame to hand a V8 with 350+ horsepower conversion and not tear the frame up?
What trans/t case combo are you using? I ran a 351W with a Marks tcase adapter into a 4 spd. It
was a 400 hp engine for sure. I ran 38.5" TSL SX's, after several years I stripped it down, the frame
Excuse my ignorance, is scab plates another word for reinforcing where I'll put the mount with 3/16th steel plates? Also, you suggest reinforcing my rear spring mounts or replacing them?Scab plates on the frame... then motor mounts. No other reinforcement needed for the SBC.
I'd also recommend gussets on the rear spring mounts (front end).

While you're in there and going through all the trouble, you might as well source a 4x4Labs front frame reinforcement kit along with the power steering plates. I'd also weld in a set of Ruff Stuff Specialties rear frame boxing plates. Cheap insurance and you won't have to do it twice. At the end, your frame will be fully boxed from end to end.
If you look at the frt spring perches of the rear springs you will notice they are not under the frame. They are cantilevered to the out side of it. This is a weak spot. The perch mounts want to tear off the side of the frame. So folks add a gusset from the frame to the outside edge of the perch for more support.. I believe someone sells a kit for it or you can make something. I you search this site you find what others have done. Fyi, This problem is not horsepower related.
Scab plates are what you described. Engine placement is very important to help cooling and help make things fall in to place. Searching this site is your friend.
I've got many pics & links in my build thread
