LS1 in A Chevy II

[69SS396]

Has anyone on here put a LS1 in a 67 Chevy II with the stock front sub frame and if so does anyone sell headers for this application or do you have to make them?

I think Hooker makes a set. T think someone on ebay sells them too.

I modified my fender well headers to fit my lsx engine in my 63 chevyll, It only cost $75.00

You dont happen to have any pics of how you modified your fenderwell headers do you? I just dropped my 6.0L in last weekend and am getting ready to cut my fenderwell headers up. Its amazing how the 6.0L fit better than my 283 with the stock front clip.

These are temporary until I can afford to do a turbo. The headers are over 12 years old and very thin. Hopefully your headers are newer. I only had to add #2 & 4 tubes because the head is so close to the shock tower, I had to use a 1 3/4" radius 90 degree bend. on the other cylinders. I used the existing tubes. It didn't turn out the way planned it. but will work.

Thanks for the pics, its nice to see someone has already done it and it has worked. I plan on adding a turbo to hte mix sometime on mine also, just going to be a street set-up with log headers and a S400 turbo with a carb. Just have to save up a lil more for that. Thanks again for the pics.

I wonder if it would be easier to start with a set of big block fenderwell headers and adapt them to a LS flange, since there is only a little over 7/16ths difference between the primary spacing between and LS flange and big block flange. But the down side would be notching the shock towers to get them to fit.

It's cheaper to use the headers you have.

Do they make any fenderwell headers for a 60's Mustang or Fairlane with a 351W? I understand the exhaust port spacing is the same. If so you could swap flanges and be ready to rock. Dumb idea? Maybe?:)
