5.3 LS for 79 firebird motor mounts

[KyleKetterhagen]

I am new to this forum so I'm rather unfamiliar with some things as of right now.

I am currently building a 5.3 ls to put into my 1979 firebird. I am pretty confused on which engine mounts to use. I am not fond of spending anything more than $150 but if there is no other option, I must. I have heard some people use SBC to LS billet mounts, but I'm not sure that it will work because its a Pontiac engine and chassis. So is there anybody who can clarify for me the best and cheap option to do. I am not looking for anything high end because I am not building a high end motor, just one to get me through college and be reliable for the next few years.

What year is the motor?

It’s a 79’ 301 and I’m going with what I believe to be a 90s to early 2000s 5.3

Do you have access to a welder?

I used dirty dingo mounts on my LS1. It gave me the ability to move the engine where I wanted it which eliminated the need to notch the frame for the alternator *low mount F body LS accessories.

The problem that I ran into when I did my LS swap was not just getting mounts to install the motor, but also want to consider your headers, trans mount oil pan and engine accessories. I also used the Dirty Dingo adjustable mounts, but found I had a difficult time finding headers that both fit, and provided good ground clearance. I would look into someone that will sell you individual components so that you could buy engine mounts first, and find maybe a cheap set of manifolds that fit to get you going. Then as you have more cash, you can buy headers and know they will fit the way you want.

I did exactly this when I built my 1968 Camaro. I opted for the Holley mounts, and then made my other components fit around them. I never ended up buying the headers, but I liked knowing that if/when I did buy them, it would be a drop in deal.
