408 or gen 3 hemi

Maybe I’m just too fixed on the hp numbers here.. my ls swapped mustang went 10.70 136 mph @2700 ish lb. That motor was in a Camaro before I bought it. It put down 436 to the tire.. 5.7,stock heads, with a monster n/a cam and a 6 speed. So at 30% loss that motor “should” make 566 ish hp.. hard to believe out of a 346..

I guess what the real question is most hellcats and scat packs are going how fast in the 1/4? ( mostly stock/ some mods) I’d be happier than **** to make this Dart go 10.50. I’m guessing it’s 3,000 lb ish. What’s a dependable pump gas combo for the 360 base and gen 3 base to go 10.50’s
571 dyno hp with 508 tq 415" N/A small block in a 3320 pound '68 Barracuda with 4.10 gears, pump premium, 8" 5200 converter with a fast 904 from ProTrans netted me in my first year ever drag racing consistent high 6.60's to low 6.70's in the 1/8th and 10.48 in the quarter so i'm not sure what everybody else is doing wrong but like I stated earlier your goals are simple to achieve and yes at the track the stock and also slightly modified Hellcats were easy picking.....they are heavy tanks.
