I've been kicking around the idea of swapping to G3 lately, particularly since Holley came out with their parts for the A-Body. I'm looking for input to either talk me into it or out of it.
I'll preface with describing how I use my car. I built the car to drive, and drive it hard. I drive 45 miles one way to my local autocross and don't even need to open a toolbox (normally). I competed (participated) in the Holley Moparty Grand Champion event in 2021 and intend to keep going back. (Autocross, drag race, speed stop). I have AC & PS (Borgenson box) and want to keep both. The car cruises and handles great. I want to keep that way. (I doubt the engine swap would affect either of these)
Current setup is a aluminum headed 408 with solid roller and EFI, TKO500, 3.91 gear, 18X8s up front, 18x10s out back with 200 tread wear tires and stock style suspension.
I have an 06 5.7 from a Charger with, what I was told, 60K miles. I recently pulled a head off it and I believe it has to be something around that mileage. The hatch marks in the cylinders are still there. I'd likely do an eagle head swap along with a rods/piston drop in kit and a larger cam, obviously.
I don't intend to purchase any fancy front runner belt system as I want to use the factory accessory drive. I know I'll need to notch the frame rail for the alternator and likely have to modify the K-member to accept the stock location of the AC compressor.
My dilemma is, Holley's kit uses a 73+ K-member. I have the early K. A local guy who I don't know wants $500 for a 73+ K. Seems high to me. What's the going rate for K-members these days?
I'm also wondering if I should just buy the QA1 K and use TTI mounts. I've seen someone on here modify the TTI mounts that allowed access to the factory oil filter location. I liked that! It would also be nice to know if the Holley headers will work with TTI mounts, particular on the driver side. I like the clearance Holley has at the AC compressor and Borg box. I'd also have to modify the QA1 K to accept my Hotchkiss sway bar.
Sorry for the rambletron... I would love to have the engine on a K, wire harness made, headers on ready to drop in so I can do the swap over a weekend to limit downtime of the car.
Give me your opinion. I want to hear about how much you love or hate your swap, how much of a ***** it was, particular with certain brand parts, and whether or it not it was worth the trouble.
Thanks!
