Well the madness has arrived and I pulled the trigger on putting a LS7 in my H-2. Bought from Jegs LS7 long block from gm and converted to wet . Bought Holley EFI. Waiting on Holley 48pd injectors and front timing cover and the swap will start....
have not found good header that will fit. Want shorty.
thinking of using Z-28 oem ones. Got cat back mangnflow kit ready to go in at the same time.
have best tuner in Oklahoma ready to tune...
As another H2 owner I am wondering how you plan to take advantage of the power curve of the LS7 and that tall EFI? I'd love to do the same but my H2 rarely see's anything over 3500 rpms.
Sounds like it will be a beast! Any thoughts on the transmission? I would be concerned you will have enough power to break the transmission, transfer case, or axles.
Not sure how the hi reving LS7 will do but should be interesting. The intake is fools gold as the runners in my stock intake are almost the same. Holley tells me staying with my factory throttle bodies will help low end tork. So would shorty headers. Either way I think it will be better then my 6.2L
the transmission is a brick 4L85 and will be fine without stall . Everything on the H2 is oversized so I am not worried about normal driving. I’m only adding 150 hp 😄😄😄😄
