489 budget build
last weekend I had the wonderful experience of seeing what a dropped valve can do to a engine :(. anyways I am building my 489 stroker engine a little sooner than I had expected now. here is a list of what i am putting together. the block is in the machine shop already for cleaning, boring, cam bearings and all of that fun stuff. right now i intend to run my old intake and a holley 800 from hp500 but i have a holley MPI complete efi setup sitting here that i am debating getting on here also. the intake/carb/efi is something i can switch to whatever i need later. i was going to use the probe pistons but the machine shop didn't seem to thrilled with them and i have read mixed reviews, the SRPs seemed more popular on this site. does anyone see anything that is not going to work or i could do better for a little more cash. please note that i posted this in do it yourself, boating on a budget, i do understand that there are allot of better parts out there and i know that with any engine build the sky is the limit on what you want to spend on it so please keep that in mind. i am working with what i have in front of me and on a reasonable budget. i am not trying to be the fastest guy on the water, i just want to get back out there and have fun :) if anyone has had experience with the holley commander 950 MPI setup i would love to hear what you think of it and how hard it was to tune.
what i have currently 454 gen VI block, virgin block being taken to 30 over Crane 731 cam and matching valve train to match it from previous motor edelbrock 6155 heads with Inconel exhaust valves Gil hp500 style exhaust thunderbolt ignition blaster 2 coil Crane hi-6m box Scat H beam rods 6.385 18" oil cooler on oil/stock on steering sandwich style oil thermostat holley blue pump/regulator -8 fuel lines edelbrock air gap dual plane intake hp500 carb k&n here is what i plan to buy as of right now Scat 9000 4.25 crank (1 piece rear main) SRP 142979 flat top forged piston (puts me at 9.14/1 if i recall correctly what i need to choose oil pump rings bearings head gaskets |

i forgot to mention it was getting balanced. from what i have read i can reuse my existing flywheel and balancer. the previous engine was a L29 gen vi 454

I haven't run the king bearings yet but there in my motors on the stands. On paper they sound great, but last few sets of clevite h series coated bearings have come out looking damn good

i have done allot of research on the scat 9000 and i think i will be ok. i was told on another thread by a engine company on this site that i will be fine. i have no intentions of boost or i would go forged

In my 496 stroker I used,
Scat 9000 Crank 4.25, 496 Stroker Scat 26385716 - 6.385 in. Connecting Rods - Floating Pins -I Beam Forged 4340 steel Probe 496 Dome Top +18.0cc, .060 - SRS - PHV Series Piston Set Clevite 77 Cam Bearings Federal-Mogal 4400 M20 Main Bearings King Engine Rod Bearings CR849HP Mahle - 4.310 Plasma Moly Coated Piston Rings Good results for a couple years now. |
i think i calculated my compression wrong. my heads are 118cc, i was using 110cc so now i am looking back at the probe pistons but in a dome, with a .038 head gasket i would be at 9.76:1 with a probe P4963F-030
