Sorry for beating an old horse but have searched with very little results or they are out of date. My car is a '88 Base Firebird with 50K miles and a year ago I replaced the 2.8 with a modded 3.4 but still not good enough. I now have a rebuilt LM7 5.3 that I'm going to swap in but want to use the TBSS intake or the regular truck intake but concerned about clearance issues. I'm going to use the Hawks mounts with the 4th gen clamshells and not the truck accessories so the alternator will be low however will be using my R4 compressor on the pass. side up high. I'd like to use different fuel rails and route the crossover in front and under the tb to give me a little more room up top and not sure if that can be done? This LS swap is all new to me so any info is highly appreciated.

 

Any reason you want to run the truck intake? I know it is one of the better performing units, compared to the LS1 and LS2, but you may consider an LS6 (if you can find one anymore), or the Dorman LS2. The truck intake can be made to work although it is way harder with the firebirds. Take some time to read the swap stickies in the LSX/LTX forum.
