The Stovebolt Site Forums The Shop Area Engine Shop 41 Chevy trans and Motor conversion

I have a 41 G506 4x4 Dump, with a 235 and 4 speed. I must admit I am unsure of what the stock trans is (sm420 I think) Maybe some one could fill me in on that. I am looking to put a SB350 in it. My issue is the trans. The current trans has the PTO on the side that I need for the dump bed.

So I guess my questions are:
1. Is it possilbe to use the stock trans?
2. Would I be better off using a SM465?
3. If I were to use the sm465, will the PTO side mount from the old trans bolt to the 465?
4. What modifications to the clutch linkage will be necessary if I went with the sm465?

Thanks inadvance for the info!

This topic would be better suited for the hipo shop.

If you have a 41 transmission, it will not directly bolt up to a sbc 350. You will have a fair amount of work figuring out the brake and clutch pedal setup. The brake and clutch pedals mount to your bellhousing now.

There is nothing wrong with keeping a 6 under the hood either. If it were mine, I would build a 261 and leave everything behind the engine alone. Of course if your truck is the gmc version, which I think it is, it would likely have a 270 motor. I would strongly consider rebuilding that motor or replacing it with a gmc 302.
