The part about a big valve head was to address having a stock cam but wanting more airflow.either for a stroker or otherwise. With a turbo idk? Maybe jezza would have something to say about that?
Jezza likely knows a good amount about this topic. I believe he said something about a 300hp build being a good balance for power and reliability. He would know since he's been pushing things I haven't seen others push things.
Also, if you make a legit boosted stroker, you then need to address the transmission. The second I think about this, it reminds me to leave things alone...whether that's a stroker or a boosted 4.0L.
Turbos also scare people off due to the belief that it will make the engine unreliable, so I understand where you are coming from.
The lifters i don't have any links but i do remember seeing pics of new lifters ground to the wrong shape and with other poor tolerances. Hylift johnson was one of the few remaining decent companies. But who knows. They are probably bankrupt or made in china like every other industry now
Over the winter, I read that currently offered lifters are pretty much all made in the same place these days. Not sure if it's true, but it wouldn't surprise me. Reviews aren't great on any of the brands RA carries.
the way russ explained stock vs stroker to me was by comparing small and big block motors. A big cam,port or valve for a small block will only be adequate for a big block.he was disappointed in me when i insisted on going with a smaller cam than
@SkylinesSuck . I probably wouldn't have lost much off idle torque and would have had impressive wot gains. But hey i can still do a big valve ported head and larger cam later!
I would have gone with the smaller cam as well if it meant my build would be more reliable. Is that why you went smaller? I assume that his disappointment was based on him thinking that if you go with a smaller cam, then why do some of the other stuff you chose.
When i compare stroker 280 ci valve,port and cam size to lets say the 289 in my old mustang it really is a lot of flow to be asking of the amc per cylinder. I imagine a turbo 4.0l could benefit from more air too. Cooler egts and power? I know exhaust volume from chamber to turbine can affect spool up. Doesn't mean flow is bad though right?
My EGTs stay in a nice range, so I'll likely sell the gauge when I install the slate gray interior.
Most of what I read stated that cooler EGTs mean slower flowing gasses for spooling up the turbo. Many guys wrap their exhausts to keep the heat in so things will flow faster. I wrapped things to lower the under hood temps for IATs more than to help the gasses flow faster, but flow is no problem since the piping goes from from 2.5" to 3" after the downpipe.
I'm not disappointed in my power and don't seem to have problematic heat issues. For that reason, I likely won't change things when I'm happy with the power and reliability of this package.
Years ago now, there was member who built a stroker to pair with his Banks Turbo...and ported things to add more flow. He later mocked himself for thinking he knew more than Gale Banks because Banks said their kit was built for a stock motor. He said that his stroker didn't perform well with the turbo, and he sold the turbo since he had just dropped $$$$ on the stroker. Bummer all the way around except for the member who now runs his turbo in the NE.
We know Jezza is running his turbo with a stroker. I haven't directly asked him if he'd suggest doing a turbo, stroker, or turbo'd stroker. That said, I wouldn't trust the 42RLE to stay happy with a turbo'd stroker. Would a manual hold up better?
