Won't work, it's mounts are different form the w-body platform, but Grand prix's will work! Thats what i mean my L67 swap soon. I'm waiting right now to see if the info from the guys who are trying to put the 303hp GXP engine in will work out, then i'll go that route.Wow! What a shape looking ride. Nice work. I usually find them rather blah, but I love what you've done. 3800 out of a Bonneville SSEi would be dope in it. Go like a scalded cat!
