For those who've done the LS1 Swap

[bwilli2]

I'm putting in an LS1 into my 51.

And as a starting point... how far back from the end of the frame rails did you put your motor mounts? The engine I have has the Chevy Small Block adapters installed, but either way.

I know the only way to be sure is to put the cab on, but if I can get in the infield of the ball park before I do that, that'd be great.

Thanks in advance for any info.
