360 vs 383
Then I threw a 200,000 mile 360 mag with a oregon regrind and a speedmaster intake in our Long Bed D150 and went 13.0's against a head wind in it's only time out to run the 1/4 mile. I think with no head wind it goes 12.9's. It does have 4.30 gears.
This in no wise means I like a 383 any less.... I love all mopar engines from the "day"... just take them in their form and what they are..
