Hooker mounts or headers for the 66 GTO?

Hooker does offer the common type 1" set-back plates to allow you to position your engine in your chassis, but we currently do not have LS swap application headers for pre-1968 A-bodies in our product line-up. I hope we add those to our development list in the future as I like them quite a bit.
Engine height is the key in the 64-67's. It has to be high enough to clear the steering center link while still remaining as low in the chassis as possible for hood clearance, tunnel clearance and driveline angle. This makes oil pan choice crucial as well. I used the mast hotrod pan and still slightly "clearanced" it with a grinder for more centerlink and tie rod clearance.

Thanks guys. I am thinking the dingo mounts might be the ticket. However, I was thinking that these might keep the engine up too high in the car. What swap mounts are proven for this combo that would keep the motor as low as possible?

Personally I would use the new Holley pan and for mounts, I would get the Holley second gen f-body engine plates and then add the corresponding engine mount clamshells to the frame. This should keep the engine as low as possible If clearance for the headers becomes an issue, it will be very easy to shim the engine up as needed.

66 gto is similar to a 66 chevelle, correct? We tried fbody Pace setter headers and they fit but tight. May have to dent here n there but they fit. I had no frame mounts in the car though. I tried an fbody & lsa oil pan. Both fit but may need to notch the frame on the fbody.

Verdad Gallardo I would not feel very confident in using the Hooker 2nd-gen mounts engine brackets in his application as they feature an asymmetric design to center the engine in the subframe of a 2nd-gen. If I was going about that swap I would probably use the new Hooker G-body swap mount brackets since they are symmetrical in their geometry and actually lower than the F-body brackets. Shims could then be added as needed to bring the engine up to the desired height as you suggest. These new brackets are in the middle of their first production run now and will be available within the next two weeks.

Because of their unique geometry, the LS swap components we've released over the last two years will not work for other applications in 9 out of 10 tries to do so, which is why we discourage their use in such a way as much as possible. Hooker still offers universal swap plates for such applications for folks that want/need to go that route.
