Just a heads up the coolant hoses, Northern Radiator makes a small block conversion setup that uses some short rubber hoses and some 90 and 45 degree stainless elbows. I used the exact same hoses you did w/adj. neck at t-stat but I just don't like the way mine rubs on the vc. I was planning to fab an aluminum support arm until I found this.

WooHoo!!
I got my 4th gear and a/c working. Only 2 weeks before we leave for Colorado.
The tranny guy liked my rig so he tricked out the valve body and put in a corvette servo.

I drove it yesterday in 105 degree heat and the temp gauge stayed on 190 F. so it appears the radiator was a good value.

I will try to get some numbers on mpg now that the tune is close and 4th gear and lockup are working.

Is a mercruiser a Ford or Chev?

texcat101

Just think mercury boat motors remarketing a 4.3 vortec (GM)

Adam F

Mercruiser also does Ford motors...the Mercruiser 470 for example is a 3.7L Ford engine

jeffbland

any pics on how you did the fuel? im in the middle of this same swap - the intake manifold .. motor is from an 04 and im almost done moding out the oil pan to fit my ifs

texcat101

I am not sure this will help you but I just ran the high pressure hose to a couple of GM quick connects that I ordered on ebay... 3/8" and 5/16" I think.
Good luck on the swap and sorry for the delay.

trdwssrs

will this intake work on the mercruiser 4.3L?

sorry for this dumb question...

texcat101

Yes, if it has the 8 bolt pattern it should work. Early 4.3's had more bolts in the pattern

jeffbland

thanks for getting back to me.. that does help!

New fender flares and BTW still loving the 4.3/700r4 swap

dannomite

LIVES4CRAWLIN91

Great swap! This is exactly how I want to set up my 4.3 (mutliport marine intake, MS II) I do have one question though. did you need to keep the ECU from the toyota to run anything inside the cab or does the MS take care of it? not much of an electrician so I thought I'd ask
Thanks!

I scraped the yota ecm but had a manual with a decent diagram to find the wires that I needed to incorporate into the new setup from what I remember it wasn't much that had to be retained from the ecm wiring... I just took it one system at a time and worked thru it
Good luck with the build!
I have been driving mine daily and still love the swap!!

Installed realtime barometric correction today in the megasquirt ecm it only cost $20 for the parts... an extra map sensor and a 1k ohm resister
Now I can drive from sea level to the top of the Rockies non stop and have constant barometric correction... you never know when you might need to do that!

Very nice build, I am currently working on a build with megasquirt (v3 board) and a 99 model 4.3 vortec. I have everything wired up and working minus the ignition system. I'd be interested in more details about your EDIS setup (part numbers and possibly sources). Right now I am direct firing the coil with the high current driver but am having issues with the distributor. Any help sourcing parts for the EDIS without having to pay an arm ad a leg for them would be greatly appreciated. TIA
