have used mmr 2015+ crank gear and oil pump gears for sale. paid over 300 asking 200 shipped paypal
both are used and show signs but are in fine working order.
have some used head studs here. sold my motor and replaced it with a built longblock that already had them.
they are 300 new asking 150 shipped via paypal
let me know
how come nobody suggested that it could be a lifter?
before i swapped an engine i would remove the front and top covers and check for any issues with valvetrain.
use some starting fluid and check for any vaccum leaks. if you don't find anything between the cylinder heads to maf; my guess is they need to get your tuned dialed in..!
this is super cool. xtreme di is doing good things for genv chevy guys too i see
keep up the good work; i love to see the technology continue to improve ET's
really dude?
yeah in these cases i take a 1/2" or 5/8" heater hose and put it up to my ear and i go fishing with the other end at the exhaust flange or welds to 100% rule out if i hear any leaks.
i hope you don't wind up needing a motor OP
best of luck
in my opinion it's not necessary unless your looking for pro-mod power. i have built 6 coyotes that hang out around 1000-1200 hp and have never lifted a head. the ones that break seem to be unlucky with broken crankshaft or other lower end mechanical failure.
