Same intake, designed to fit LT4 heads, doesn't flow any better.

The LT4 just has higher port location. It matches the ports used on LT4/Vortec/FastBurn Heads.

OH, I almost forgot, the LT4 intake is RED!!!

I've never seen anything about it flowing better. As far as i've heard from camaroz28. Its the exact same thing, has a little more meat to port. Check out camaroz28.com yourself and do a search. People have already mated it to LT1 heads. Been done before. It flows no better than a LT1 intake.

Do you have flow numbers for the LT1 and LT4 intakes? I have looked all over for them with no luck finding any info.
