I have read a bit about the LT2 Intake for the LT1. Its so cheap $230 from GM, Are you able and willing to port this New LT2 and modify the back end so it would fit on my 2014 Corvette? I understand cutting and lowering the rear of the manifold to match the LT1 profile is required. I do not plan to add boost, Running NA and want a cost effective way to pick up some power. Retired and on a budget but still have the bug to modify my C7 Z51. It has 10,000 miles and I want to drive and feel a little extra. I think you could help if you can I would appreciate it. I did not want to cut the cowl of my Corvette but I will if needed. Thank You for supporting our hobby. Dennis

I have been looking at all ported upper intake manifolds. I like this option to look 100% stock and still use all stock covers. Is the price listed for the mani and the porting or just to port my current manifold? If it is just to port mine what is the turnaround time? Can you do a core charge? You also state 6-10 hp. Is that with a tune or stock ECM?
Thank you,
Ken

The 6-10 is without any tuning. It is for porting of your manifold. We do not do a core program on the LT1 manifold. Usually we can port your manifold within a weeks time of receiving it. Hope this helps, let us know if any other question.

Will porting accommodate an LT5 throttle body?
-
A We can open it up to accommodate the LT5 throttle body. That is as far as you can take it. You will also have to elongate the bolt holes on the TB to fit. Thanks for checking with us.

If only porting the intake you will not need a tune. If you have the TB ported it may need some idle stuff touched up. Here is the Remote Tune Update pricing.
