What engine? 5.3 or 6.0?

What transmission do you plan to use?

What are your rear gears?

That's a GM A-Body vehicle. Holley makes a fabulous set of engine mounts, oil pan and headers that are tailor made and engineered for A-Bodies. I have no complaints about their equipment on my 70 A-Body El Camino.

@Supersmoke318 When I did my ls swap I used ICT motor mount brackets, they are cost effective quality and full beef. What transmission are you planning on running in your car? it would be a great opportunity to swap to an overdrive transmission!

Do yourself a favor and use the Holley swap components. They offer the most optimal engine placement that results in much better driveline angles.
