    yes I have a 2019 GT350, which they put a GT350R motor in (from factory). Not sure what you are trying to say.

    Im confused. I was under the impression it was confirmed that the pre 2019 GT350 and GT350R shared the exact same engine. what is this now regarding GT350R valvetrain components being different?

    This is only relevant for pre-2019. All 2019s are 555.

    • GT350R Timing Chains
    • GT350R Lash adjusters
    • GT350R Cam covers
    • GT350R VCT mechanisms

    Both the Gen3 Coyote and the new Voodoo block use the same valley casting. As such, both blocks have 6 knock sensor bosses cast in. The gen3 Coyote uses the 4 outer bosses (sensors); the voodoo still only uses the 2 interior bosses.

    Looks like the Gen 3 Voodoo block may be a good foundation for a short block build for a 2018 GT since they share the same valley casting and the voodoo block has the right number of knock sensor bosses for 4 sensors .

    It might be an alternative to buying and sleeving a new Gen 3 block .
    I am assume the 18 heads with DI will also work with the Voodoo block .

    Just picked up my 2019 GT350 a couple of weeks ago. It's tag is K0019, and looking at the door jamb sticker, looks like it was manufactured Feb 7, 2019. So got to be one of the first ones off the line. Looked under the engine cover and yes, it says KA and 350R, so definitely the new engine build. :)

    Too bad they couldn't eek another 14 hp out of the voodoo in its (possible) last year or production with all these improvements. 540 hp is a nice round number. :)

    The motor is high-strung as it is, there'd have to be a lot of improvements to reach that number. Not worth it for the last year and half run of cars. Low production numbers, and you have to recertify the HP figures. Easier said than done.

    Everything I had read indicated the GT350 and GT350R shared the same engine prior to the 2019 model year. To now hear the GT350 R was different than the GT350 is a real revelation.

    That’s an interesting thought. A DI 5.2...

    Would it work?

    To sleeve a Gen3 Coyote bored to 3.700", you're looking at about $3600. depending on where you get the block. Less if you go stock bore. The Gen3 has a more open deck than the Voodoo, but a shouldered sleeve might equal, or improve it over, the Voodoo block.

    My engine builder can get me a Gen 3 Voodoo block for about $2500 so that’s some saving .

    Any reason whey the DI heads would not work with the Voodoo block ?

    I have a complete voodoo rotating assembly (new but Gen I pistons and rings ) and had been considering building a “spare “ short block starting with the Gen 3 Voodoo block for my GT350 but now considering using a CP and building a “5.2” spare for my 18 GT instead (if they Voodoo block will work with DI heads )

    Either way I could reuse the OEM Voodoo pistons (already have the dimple for DI) which are said to be a high quality Mahle and upgrade the rods for some more savings ..

    Cost for the FP build was going to about $5600(with Manley rods ) and for the CP another $300 since I would need a crank .
