I have a 418" stroker '72 340 block in my street driven Duster. It's got a .040" bore, Eagle forged 4" stroker crankshaft.
Scat I beam rods, ARP hardware on the rods. 10.1 Icon forged pistons. Stock main caps/bolts...
Clevite bearings. Heads are factory J casting's that have been fully ported and polished, stainless Ferrera
2.02/1.88 valves... Indy roller rockers. Edelbrock Victor single plane intake. Cam is a Bullet Racing solid mechanical with .248/.250 @.050
lift..530 intake...LSA is around 106 IIRC. Never been dyno'd but should be good for around 500-510 H.P. Mine has been built since 2013, and it has roughly only 700 miles on
the drivetrain. I use the car for street driving and car cruises. It never has been to the track since I have owned it, but I think it should be good for easy low 12's with street tires, and 11's with drag radials...It never goes past 6k rpm. I haven't had any issues with this engine at all. BTW car is currently for sale..
