I went big block in my 68 GMC about 20 years ago.
Used a .060 454 4bolt block, steel crank, micro oval port heads hogged out to use 2.19in stainless valves, Performer cam and intake, HEI. Doug Thorley Tri-Y headers.
Did not have any clearance issues as I moved it all forward 2.5 inches, used all factory 72 Big block pulleys and brackets, stock V8 crossmember and a V8 2WD fan shroud,

I also have been thinking about putting a 502 in my 67/72 mix but my question is did any of you have to add a leaf in front to support the additional wheight? Or did you just leave them alone?

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

I did not do anything to my front springpacks and all is working fine :metal:

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

I am running Tuff Country's HD front springs that give you the extra leaf. Not sure if it was needed in reality - not like I'm gonna have a winch up there anytime soon.

so iam getting ready to install my 396 in my 4x4. and it looks like all the firewall bashing is around the clutch rod hole. iam using the stock cross member with poly mounts and would like to use the stock holes in the frame. will it fit?? i would like to see some other pics out there.

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

Hate to tell you this, but you just won't know until you put it in place. Some need no modifications to put in the stock sbc location, some do. I had interference on both sides using the stock sbc crossmember, new rubber motor mounts and the stock sbc engine location.

Would a body lift kit help clearance issues?

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

A firend of mine works on Fords and runs into the same problem about engine placement. Just because the trucks are from the same plant doesn't mean everything fits the same. I have two 4x4's with 454's in them. The 1968 I moved the engine Forward aprox. 2" and put 2wd Jethot headers. Small moons had to be made in frame for a good factory look. The 1970 was not moved forward. It has low cut valve covers and the drive side is still tight.
The exhaust manifold is still stock. Both trucks are long wheel base which helps with the extra weight up front, not so much kick. I had to put bigger lug bolts on because of the added weight. Both trucks are 1/2 tons with power steering. The 68 has disc front and rear and the 70 has disc front.

Usually a body lift helps with HEI clearance and also with the valve cover clearance - but - I used a body lift and still had clearance issue at the valve covers. Again, you just really won't know until you slide it into place.

just be sure to keep a can of primer near by if needed

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

iam getting ready to put my 396 together and was wondering what oil pan works with the stock cross member. i heard that the one with the hump in the middle hits. thats the one i have now.

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

My 454 came from a 1989 2wd 1 ton - using the stock 1969 sbc engine crossmember the oil pan was extremely close to the crossmember. I ended up cutting the crossmember and adding some material to gain some clearance. Hope that helps a little.

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

i heard that a stock chevelle one works .

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

i got a 77 454 out of a 3/4 ton burb. im using the stock sbc crossmember and mounts and have about 1-2 inches between the oil pan-crossmember. in other words probly find a truck oil pan

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

iam going to get a 30710 milodon pan

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

So you should be able to use the Milodon pan and original small block engine crossmember and have no problems? Cool ill keep that in mind for when it's time to do the conversion.

Re: 67-72 BigBlock 4x4s! Pos pics info here.
 

yea thats the same oil pan i use and im on all sbc mounts
