I ran 4.56's in my tube chassis street Cuda with the biggest QTPro Hoosiers at the time. If I remember right it turned about 2700rpm at 55. Also ran 4.30's in my 62 Dart 330 with (I think) 28' Hoosiers. Those 2 cars where for wk end warrior street cruising though.

Edit: Now that I think about it, those 28's were more like 383man's 30's.

Now that I have my 70RR back on the road, 1st time since 1983. It's a Dana 3.54 4spd with 27" BFG's. Tach says about 2750 at 55. Calculator says it should be about 2400-2450. Car sounds like 2700-2800 to me, lol ...probably cause I'm getting used to these modern OD cars & trucks.

On the list for the A855 for longer Cruises/trips. Will make dew till I get the last few miner things fixed on this RR. Then I may do a Passon 4spd OD if he'll do a trade-in on the 5spd.

Hey...mickm wave I got her going!
