Default Ls7 head to ls3 intake adapter? Anyone use

I was looking at running a ls7 head to ls3 intake adapter so i can run a holley ls3 lo ram and a shearfab intercooler on top. Holley dosent make a ls7 lo ram. So this would be only opinion. Has any one used these or seen them in person? Do you need to modify intake due to having to add 1/2 plates on each side? Thanks

Have you looked into Mast, Tick, or Frankenstein engine dynamics, to see if they offer a similar intake but in LS7 configuration? Or reached out to shearer or any of the others about modifying one. Probably a lot more than just getting adapters though.

yeah i have looked at the 417 base a few times but the price at 1800 and it wont fit my injectors. That is why i looked at the adapters and holley ls3 lo lower. Can do it for under 600.
