i was always pleased with my .509 in my 3900lb. truck. best time was 11.69 @ 112mph on pump gas & through the mufflers on mickey thompson ET streets. bottom end was stock forged crank, LY rods, trw L2266 flat tops. IIRC, cam was installed straight up. motor had OOTB edelbrock heads, holley street dominator manifold, ancient holley 950 cfm 3 barrel, & CPPA/tti 2" a body headers. compression calculated out @ 9.5:1 with the 84cc heads.
truck had a 10" coan converter & turbo action manual VB.
8 3/4 w/4.10. & yes it was streetable.
