i understand that which is here as well. but im just saying as its a generation motor that never came in this bodystyle thats all. and im aware of anything given right person can get stickers. just was curious being its a GenI motor in a GenIII truck. I didnt think you were allowed to step back in time with motors and still be legal. Or least thats law here

 

Wow Dare to be different, hope it all comes togather for ya, runs well... A touch of ole school in new bones... Keep us posted

You could still get the Vortec SB's in these trucks till 2000 and I think even 2001or2 in the van chassis. I know his truck is 04 but I don't think you would have a problem with it unless you took it some where that was VERY strict on emissions. If it passes a OBDII test, sniffer test and has cats, I think you could register it pretty much any ware.

Now if he ripped all the EFI stuff off and put a carb and HEI with long tubes and no cats, that would be another story. But seeing how he is using pretty much all factory equipment I don't think there would ever be an issue of it.

 

Actually yea.

Day 2. Sept 07,08:

It's not 100% bolted in... lets call it 80%











I didn't have any intention to get the motor in today, but my buddy and I watched this little cloud directly above us balloon into a massive thunderstorm and we got the engine sitting in the engine bay just as it started to down pour.

The engine isn't completely on it's mount brackets. I have a feeling the trans slid forward in it's elongated slot on the cross member, enough to misalign the motor mounts up front. And the engine will sit 1.5" lower once it's completely on the mount brackets.

I've got a couple more bell housing bolts to tackle, they needed to be changed out from metric bolts to 3/8" course. The TC needs to get bolted to the flex, started motor bolted up. Needed new starter bolts, from metric to standard.

Still need to finish wiring in the new fuel injection harness and plug in every sensor harness.

And,The K&N FIPK for 4.3L did not need to get modified at all to fit on the V8

We also mounted the secondary trans cooler. Yes I know, I have some aligning to do... of the bumper cover and the cooler.

Lookin good Mykk

 

Question. Where are you getting you ECT (engine coolant temp) input from for you PCM? Are you using a sensor in the head? I ask because all of the L31's I've seen, used the sensor in the thermostat location, but you have that port plugged.

 

Yes, I transferred the coolant temp sensor from the head of the 4.3L over to the head of SBC.

 

Thats what I figured. Do you think it is better in the head over the spot in the intake manifold? On my engine the sensor in the head goes to the dummy gauge in the instrument cluster.

 

This has got to be one of the coolest swaps I've seen so far. But man, that old 350 just looks weird in there!

 

Very cool, I've been following your engine build so I'm very interested in the swap too That small block looks right at home in there
