Well, that is good. There is a nice spot for all carburetors right in the trash can. I have no issues with TBI but it is surprising how many people ditch TBI and go back to carburetors…. TBI is a very easy and reliable system to run.
I have a Marine L29 7.4L MPFI intake, ECM (RamJet 502), and harness (RamJet 502) available that I ran on my K10 for a short while before the 8.1L swap. If you are ever interested PM me.
This is the marine L29 intake on a 454HO running a RamJet 502 controller and harness before the 8.1L engine swap.
While LS swaps are popular, an 8.1L swap is much easier, as it bolts right in and you can reuse your 454 headers, manifolds, etc. Harnesses and PCM tuning options for the 8.1L have really grown in the past year. Turn off “Torque Management” and add a 87 octane hot tune to a 8.1L will get you over 400 HP and 500 lb ft of torque with a stock cam, injectors, etc. I am extremely happy with mine. The only thing I would consider replacing it with would be a Cummins and I doubt I would gain much power…but more MPG....and engine weight.
