I just pulled my I6-250 to swap in a V8-350. don't have the SBC yet, so....

what accessories, brackets, etc. should i remove from the I6 because I will need them for the V8? plan to sell or give away the I6.

engine mounts? flexplate? starter? power steering?

thanks,
tom

All the brackets are different. If you decide to give away or throw away let me know I'll come and get it.

Actually, if you want the V8 mounted in the "correct" position you will need a set of V8 engine stands as well (part that bolts to frame and crossmember). Plenty of guys have put their v8's in the I-6 position but the motor will sit farther back and if you run HEI it will be pretty close to the firewall. Are you sticking with the trans that's in it? Not sure how moving/not moving the engine stands will affect that.

RUbber engine mounts, flexplate and bolts, starter, alternator, oil and temperature sending units.

My blazer is a 4X4. From what I have been told, Chevy had the engine close to the firewall on these 4X4 trucks. Sticking with the sm465 and np205. Although I would like to move the V8 forward, I think shifting the engine, tranny, and transfer case forward would cause problems with the front. driveshaft . Do I have this wrong ?

Awesome, thanks, how about the wiring harness... for the connectors perhaps?

Mine was swapped from an I-6 to 283V8. It sits way back clost to the firewall but it still works ok. I've got a non-HEI set up so that might be why it works for me. It does but the fan pretty far from the rad though.

Just lay the harness out of the way when you remove the old engine. It's part of the truck. Then you can modify it as needed when the new engine is in place and the harness draped over it so you can see which wires you want to modify to fit best.

Thanks, makes sense now that you mentioned the obvious. Guess I forgot to mention I pulled the body off the frame, wire harness off the body/frame, so I sort of left the harness move with the engine. I'll keep the harness to re-install if I don't buy a new harness.
