RJ, here is how the 360 evolved in the DP cars. John Donato, a Mopar engineer did the stuff on the DP motors. The 360 was actually put in for the SS racers so they could at least have some new parts in SSGT. The motor is an old 360 Magnum which has been around since 93, The block is the same except everything since the mid 80's had hydraulic rollers. The Magnum used individual pivoted rocker arms similar to a small block Chevy. The heads were steel and better than the old LA small block Mopars. Then Mopar made the R/T version of the Magnum head which was better and it was made in a small valve and big 2.02 valve. Mopar has not made either in many years. So the Edlebrock out the box was the logical choice, and it is only made with 2.02 valves and small stems (the stock heads had small stems) The pistons are flat with notches and are 120 grams heavier than a stock truck piston. I think John put a 5 where there should have been a 4. The cam is 490. The manifold is a Mopar M1 which has been around since Chris arrived on Santo Domingo. It is made in a Magnum and LA style, the difference is the bolts; the Magnum has vertical bolts. The throttle body is rated at 1000 CFM, the bores are the same size as a 750 double pumper. That motor will make more peak hp by about 10, with a good 750 or 850 race carb. With an engine management system, the average is about the same. The heads use Chevy rockers. There were 3 360 cars build in 2009 and none in 2010. Uses a race pan if you have the Mopar Performance block, and a Dakota pan if you use a truck block. It is the least trick motor of all the DP motors.
And now you know. There were 7 or less 5.7 Hemi motors made. The rest is 6.1. And that is your history lesson today. Test tomorrow.
