Building a 1988 trans am I just dropped in a 2003.5 5.3 with ls6 intake comp xr265hr cam and hooker blackheart headers, Backed by a freshly rebuilt 4l60e with corvette survos and a s10 converter.Im using the blackheart exhaust and transmission crossmember with bmr k member and a-arms.
Just need to put in the fourth gen fuel tank and 3.42 posi
Looking good,that will be a blast to drive.
How long have you been working on the swap?
I like the engine painted orange,it makes look like a sbc at first glance.
Iv been working on it since June the biggest hold up is getting parts delivered in a timely manor, the bmr k member took two months to get. I was very happy with psi conversions they shipped the stand alone harness fast, The bulk summit order including the giant hooker boxes was comical completely blocking my apartment door looking like gear head Christmas, It must have sucked being the ups guy that had to carry all of it up three flights of stairs.
I love that psi harness, it’s not too expensive and makes the swap so much easier. 5.3’s are great too. You get the best of both worlds, way cheaper than a 6.0 and more stroke than a 4.8👍. Looking forward to seeing it come together.
Yeah 5.3s are a steal, Picked one up on craigslist for $450 complete with harness ecm and accessorys. I didn't want to deal with modding the stock harnesses for ev1 injectors and car coils. I'm dreading stripping down the body harness.
Nice looking Trans Am! Of course I'm partial to the Red/Silver combo also. I know the pain of working in a small space but looks like you're getting it done!
