Engine Pro's Help please
I am in the middle of building a 410 stroker from an LA 360 Block. I am using an eagle 4340 crank and eagle H beam rods with SRP Dish pistons at 16.9 the girdle from Hughes was installed yesterday and the mains are getting line honed, the lifter bores are being sleeved as I write this. I am also converting it over to push rod oiling using Hughes stage 3 edelbrock heads port matched super victor with a 750 might demon with all the tricks from Don at FBO, 1.6 Hughes rockers with JOMAR valve train girdle and Hughes Hyd flat tappet cam specs
Intake Valve Lift 1.5
Exhaust Valve Lift 1.5.569"
.576"
Intake Valve Lift 1.6
Exhaust Valve Lift 1.6.606"

Exhaust Duration at .050"246°

Exhaust Opening at .050"18° BTC
56° BBCIntake Closing at .050"
Exhaust Closing at .050"48° ABC
14° ATCMin. Suggested Cylinder PSI185Sweet Spot RPM2800 - 6100
The compression will be 10.9:1, elevation is 1226, cylinder pressure will be in the 190 range and this is a 4spd................
I was told that the oiling holes that get machined in the sleeve need to be no more than .060 and that would get enough oil up through the pushrod to oil the top. When you reduce the oil flow like that does it have an effect on the over all oil pressure?? Will it sky rocket or??
Another question I am debating on swithing to a solid flat tappet or roller cam set up. I have already bought all my parts that are listed above, and am second guessing my cam choice. This build will mostly be used on the street.
Any input you may have will help............
Thanks.
