frame strength questions
how heavy of an engine could a F1 frame hold with stock components, reversed eye mains, and every other leaf removed, without boxing the front, safely? How much does a flathead weigh? ( just wondering, before I get into modding the frame before sandblasting). I'm even considering using my IH345 cid., since the mounts are on the front, but I think it'll be too heavy.

The frame will handle the weight of most any automotive engine. The strength issue requiring boxing becomes that of engine torque twisting the frame. The unboxed frame and front suspension should be good to ~ 400hp. Independent engine mounts that attach to the frame may require boxing or reinforcement in the area of attachment.

Interesting engine swap though. My brother's 79 Scout II had a Chrysler 700 torqueflite behind it. Easy to rebuild and easy to get parts for.

mine came from a 78 scout II w/727, but I didn't keep the tranny. It's a 4bbl intake, so it only weighs 79 1/2 lbs.
Thanks Ax, I think I'm safe then. Mtflat thanks for the weight, gives me a ballpark figure to go with. I know a IH v8 is heavy, but I don't think it's any heavier than a 460. I gave up looking for a K-series panel truck, so the engine's just sitting around.
