LS7 Swap into '97 SS/LT1?

Has anyone here done a LS7 engine swap including the dry sump system into a 4th Gen Camaro? I hate to give up on the LT1, however, it is the weakest link in my super fun HPDE car. The swap would include the dry-sump oil system and a/c (for driving to and from the Track!). Where can I fit the oil reservoir? Do I have to abandon the ram air hood function? How do I accommodate the 58x reluctor wheel? Currently I am running the Torqhead 24x LS PCM Coil Conversion Kit. Does the extended snout for the oil pump on the front of the crank cause any clearance issues? Can I use factory LS7 exhaust manifolds or ??? Just installed a SPEC aluminum flywheel and clutch )-: and T56 was just rebuilt. I would have the input shaft replaced on the tranny for the LS conversion. Any help would be appreciated on this start of my journey.

I imagine the start would be an LS crossmember. I think Caspers makes a translator for the different reluctor wheels. Are you currently using an LSx PCM to run you entire powertrain? apparently the LS7 crank is about .886" longer than other LS cranks. IDK if that makes all the accessory drives have to be spaced out for that or if it just uses a shallower crank pulley.

I agree with the replacement kmember as the starting point. For the functional hood, the scoop would still be pulling cool air into the engine bay, but with the difference in intake manifolds, I can't think of an easy way to mount the air box. maybe come up with something creative with mounting to a strut tower brace?

Thanks for the feedback but it is too late! It's been a great 23 years off and on the track. But the '97 SS is now in semi-retirement. Shifted to the 21st century with a 2020 1SS 1LE 6 speed.

Flew to Washington, drove it off of the showroom floor, broken-in on the way home to Cali and shortly onto the track at Thunderhill Raceway. Chevrolet did an amazing job of testing, developing and fine tuning the suspension, brakes and tires on this car along with the ZL1.

Thanks! I love the color! A few people have talked about how heavy the 6th gen feels. Since you have track time on both platforms, what are your thoughts?

Re: LS7 Swap into '97 SS/LT1?

That was one of my main concerns. The new car is 240 lbs heavier than my '97. However 220 lbs of that is at the rear. So the actual front to rear balance of the weight is 54% front 46% rear. The '97 is 57% to 43%. Although any additional weight is not good I found the car is better balanced at turn-in. I am able to trail brake (brake steer) on turns. Also exiting turns has a feel of very controlled drifting. I was running race tires with a 50 treadwear rating compared to the new car with factory 220 treadwear tires and my lap times are almost identical. I still love driving my '97 but I enjoy driving to and from the track more often with the 1LE and a much shorter to-do list!

Nice. With tires you should be ahead. What else is on your list for the new ride?
