Have a 73 rr clone looking to drop a 383 in it. Is it possible to get in the 13's if so what set ups can I use? Cam, gears and stall?

What gears did you have in the rear end?Wont be hard at al
My coronet got into the low 13's with .484 purple shaft, performer intake, 800 carb, 2800stall
Had a 3.91 gear, I'll note that the carb was too big for the motor and gear wasn't good for highway use. Probaly would've went faster with a better intake and smaller carbWhat gears did you have in the rear end?
You think 3.55s could work with the same setup?Had a 3.91 gear, I'll note that the carb was too big for the motor and gear wasn't good for highway use. Probaly would've went faster with a better intake and smaller carb

Now I know my engine is rated at a 10:1 compression so could I possibly run a cam with a .509 lift and 292 duration with the same gears and stallAbsolutely
Yes, It may call for a certain minimum gear and stall so just make sure you have everything you need to run that cam. Is that the mopar purple shaft cam you're looking at?Now I know my engine is rated at a 10:1 compression so could I possibly run a cam with a .509 lift and 292 duration with the same gears and stall
That's what my dad recommended to me but I was also looking into comp cams because they have the full valve train kits and it seemed like I could save a little money with that full kit and replace everythingYes, It may call for a certain minimum gear and stall so just make sure you have everything you need to run that cam.

Go with a comp set up, or lunati.That's what my dad recommended to me but I was also looking into comp cams because they have the full valve train kits and it seemed like I could save a little money with that full kit and replace everything
Thanks for the adviceGo with a comp set up, or lunati.
That does seem quite good for a stock 383 without mods.Mine may have been an anamoly but it ran 13.35 when new with nothing but a little tweaking on carb& timing. Course that was awhile ago(late '68,early '69) used to always wonder why the RR's didn't seem quite as good!
