Hello, I have a 71 roadrunner bench seat four speed sassy grass green 383. I built the engine myself about 15 years ago. It is .030 over with trw +22.5 dome slugs my dad had laying on shelf and 906 home ported heads. Cam is comp solid roller at .550 lift and 288 duration advertised. Intake closing is 70 degrees abdc. Poor choice of cam with such high (11.6) compression. Runs a 13.6 1/4 mile at 106 mph at 33* timing, street tires and 3.91 gears in an 8 3/4. I plan to build a new engine this winter either a 470 or 512 using a 400 block, and tf 240 heads. I recently this summer installed the 855 from Garret and fuss inc. sweet 5 speed and McCloud dual disc 800 hp clutch. I have been working on mopars with my dad since I was a kid and we have had this runner for nearly 30 years. I've been reading a lot of the forums on here for years and I've learned a lot from doing so. Thank you all for supporting my favorite hobby.
