LS Swap Seafari 25

Here is the test fit. Should be installing tomorrow and getting it started soon I hope.

So today we tried to start it up. Crank no start. The ligenfelter trg-002 is blinking all red indicating no crank shaft input. I did reuse that sensor. I purchased a new one this evening and will be installing and go for start tomorrow.

I told wife I should just fire it up at 9pm tonight and was given a very stern no… especially as she teaches the police officers kids who live 2 doors down from me.

Oh well. Morning is coming. Maybe 0600?

Good luck! I have a new 454 in my 1978 23' Sceptre that has not been run yet myself (waiting for boat to be finished from a project that has taken WAY too long). Please post pictures and I'm sure the neighbors will understand.

Sounds great water rat. Still no joy yet. I’ve got to double check spark and some wiring issues from this harness. I think I’ve identified the issue.

On the plus side the crank position sensor turned the trg from blinking red to all red. Meaning not talking to pcm. I think the pcm has a power supply issue from this harness. Another day of trouble shooting ahead.

Ugh, I feel your pain. I'm sure nothing that several hours and a few ounces of blood and sweat won't cure. Good luck and keep us posted.

It’s alive! I feel like Frankenstein…

I don’t care how many you’ve done until it’s running you’re scared…or it’s somebody else’s money.





I’ll try to make a vid of it running…it sounds awesome. Deep and throaty. I love it. Still working on the idle but it’s figuring it out.

Congratulations! Would love to see some video and hope to be reporting similar news myself soon.

Awesome! Hope you get to dip her soon!

And here is a short video of it idling. Nothing special but it’s nice.
