I just sold my genII sbc 327 from my 70 chevelle. The buyer passed on the headers and now I have those to either sell and get $100 for or I was thinking of modifying them to fit my 4.8L.... Has anyone ever done this or heard of this being done??? Headers are expensive for these motors nowadays!!!

I plan on adding a turbo to my car very soon, that is why I do not want to shell out for new headers or feel like paying a shop to add pipes from my stock 4.8 headers on back...

Im sure you could try cutting the flanges off and heating the tubes with new flanges (might be tricky though). Another option if you are going to go turbo soon, you could stick with manifolds and then flip them when it is time for the turbo and fab your cross over pipe. Just a thought.

X2 stick with the truck manifolds.

Be easier and cheaper just to add some pipe for the truck units vs redoing the headers.You would have to buy LS flanges anyway for the headers. Just sell the Gen I headers and run the trucks manifolds.

You are better off picking up a cheap / used set of BBC headers... cut the flange off and weld on some new LS ones.. will be a lot less work than trying to do the SBC ones. also. since they are for the Chevelle / A-Body, the BBC should be very close to fitting, depending on where you mount the LS engine. The BBC header would be close to the tube / cyl spacing in the first place.

so I can keep the truck manifolds on there and run pipes from truck manifolds until I get ready to turbo??

I didnt think I could run the pipes from the stock manifolds...... Clearance issues..????

Either way you're really gonna have to "pull" some tubes. Gen II SBC has the same 4.4" bore spacing as the LS, but unevenly spaced ports. BBC has evenly spaced ports but 4.84" bore spacing. If you have access to various headers look at small block Ford stuff, they have the correct bore and tube spacing.

S10, I was just going to suggest that!
