Help needed: swapping out 292 for a V-8 in a 4x4
 

Tech question here, not sure if I should post this in the engine, 4x4, or this section....but here it goes....
Have a '69 Suburban 1/2T 4x4 with a 292. I pulled the 292 out, going to get a Big Block.....anyway, the crossmember is angled as the motor mounts are off-set. See pics.....that's a spare 454 block I had laying around for mock-up. The driver's side pretty much lines up, although once heads and V/C's are on it I think it'd be a tight fit.:(
What stuff do I need to swap in the V-8? Are all 4x4 V-8 crossmembers the same???:confused: I assume I'll need motor mounts/towers as well.

Any help with this greatly appreciated!!!
I plan on getting the parts ASAP....

So,you want a BBC in your 4x4?Well,some problems people run in to is clearance with the firewall that most people handle with different valve covers,body lifts,or moving all the crossmembers dealing with motor/tranny/t case forward.The 6 cylinders had different motor crossmembers than the sbc V8s.There was no stock BBC in a 4wd in 67-72.The 292s had the crossmember at an angle.All the holes are in the frame for when you convert to the V8 style.No drilling required.I did this with my 71.It had a 292 and now has a mild 350.Just changed the crossmember and bolted it in the right spot.

Cool...thanks...wouldn't happen to have a pic or two would ya???:)
But a bolt-in??? I unbolted the pass. side mount from the crossmember and frame and moved it back, the rear hole is off. No big deal I guess. So I can probably just use these and get just the crossmember then.....
Gotta have a BB....run 'em in all my rigs.:metal:

The minimum you will need is a V8 crossmember.Some people use the crossmember from the 73-87 4wds for more clearance under the motor.The holes should all be there.You might find they line up once you have the correct crossmember.I dont have a pic with the V8 crossmember installed,but I think I do have a pic of where it should be.Now for clearance,do you prefer to run a body lift,move all the motor/tranny/t case crossmembers forward,or take the old hammer to your firewall?

Hahaha!...Well, I'd rather not use a body lift OR a hammer. I'll move everything forward if needed, provided there will be enough clearance for the waterpump......:confused:
Thanks for the help!

Send Yukon Jack a PM. He put a big block in his 4x4, he will give you some pointers.
