The plates have three choices for mounting position:
The first position places the LS bellhousing flange in the same position as the SBC. While this is the most desirable position, many cars have firewall or other clearance issues due to the differences between the traditional engines and the LS. The LS passenger side cylinder head sits much closer to the bellhousing flange than the SBC/BBC, which causes interference on many cars.
If the first position won't work, the second position moves the engine 7/16" forward of the original bellhousing flange position.
The furthest forward position is 1-3/4" forward from the original position. We have found these options accommodate the widest array of header/crossmember/steering gear combinations.
These plates are precision machined from 6061-T6 billet aluminum and include all necessary Grade 8 or above hardware. Unlike the other guys who use a water jet, ours are made on a CNC mill for the ultimate in precision and consistency.
Made in USA!

bought the plates after good reviews on lsx nova's . nice work and can't wait to get them mounted and the car running again.
I ordered the Scramspeed LS engine swap relocation plates because I needed more room between my engine and the firewall in order to mount my coils on the back of the heads on my LS3. I couldn't go too far or my headers would hit the frame in 3 places. They did exactly what they were advertised to do and the quality is excellent. I'm very happy and recommend this product to anyone. Delivery was quick as well.
Loved the mounts and shipping was lightning fast!!
