Howdy!
Working on consolidating parts for my very slow moving LSR project and am reevaluating my current rotating assembly if I'm biting off too much at one time. A really quick run down is I'd like to race in the Classic Production Supercharged (CPS) category in the small F motor class which is limited to 123-184 cid [2.0-3.0L]. This boxes the engine into carb or mechanical injection with the same deck height, bellhousing, and number of headbolts interestingly as the production 81 B4B turbo motor. For me this means I'm basically making a taller deck 3.0L with the 2.660in stroke and 3.800in bore. With a target of 240-275hp at 5800rpm would a blueprinted factory 3.0L evenfire crank hold up to almost a full minute of WOT if I stud, billet cap, and girdle the bottom end? Cooling and oiling systems are unlimited so it'll be a total loss ice box charge and engine cooling so I should be able to keep that under control. Fuel is also race gas so it should be very high octane.
I have a forged 2.660in stroke oddfire crank and some workable rods and pistons but that oddfire setup is problematic for a cam, ignition, and other things. Pistons are the same between the even and odd fire setups though the rods change due to the different rod journal size but they make 6.350in rods with a Buick V6 BE and a SBC pin to fit the 3.0L crank just fine.
Thanks
