86 Silverado Engine Conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was wondering if it is possible to take an 86 305 and replace it with an 02 5.3? Has anyone done this, and if so what problems and mods would be expected. Thanks,

Kyle

I don't think anyone here has done it but im shure theres a 73-87 out there with a 5.3 in it.

You may have better luck posting this on the engine & drivetrain board.

Oh yeah welcome to the board

im sure it can be done but id check with the dealer they would know too

screw the dealer, they'll tell you that you cannot do it, becuase GM didnt offer the parts to ut it in, some stuff has to be fabricated. if you cant do it, why does N2Trux have an LS1 in his Blazer?

well there you it can be done since the 5.3 is a cast iron version of a LS-1
