How much compression with a Magnum?

Oh, and I will take that $100 bet if you want, 5.2 against a 340, as long as 340 doesnt have EQ's :D

So you want to pick on the 340’s baby brother, huh? That’s not right! :) Now if you want to take that bet using a stock headed 340 vs an EQ headed 318…..could be interesting to see if I could out flow you enough to make up for the lost cubes.
I’ll take it from your comment the EQ heads cannot be massaged as much as the LA heads.
I have to thank you for explaining with sufficient details what the EFI is doing/reacting to compared to the carbed engines. Explaining this definitely will help with a later builds without all these limitation this build has. Ditto for the PCMs.
If teaching is stepping on toes, tell them to go get steel toed shoes…and a hanky.
I don’t see how the red 22 lb injectors can possibly provide enough fuel for 350-360 HP—unless I run 55 psi, which means a new fuel pump. Even Deatschwerks indicates I need 25 lb/266 cc to meet that; and the only ones I have found are for Chevy LS1/LS6’s—and this Mopar diehard just cannot do that. Now if someone was to rebox them and say they are for Mopars…. Probably better if I call you on that subject.
Would you believe the 5.2 was rated for better gas mileage than the 3.9? Due to the 4 speed automatic.
You did shock me when you talked about the alignments, decking, etc. I thought Mother Mopar’s quality control was better than that—at least before she went to Mexico (which these Magnums could be for all I know). I guess I have been real lucky on the past builds I have done. I have only needed alignments corrected and one block core had bad core shift and could not be used. Then again, I am not building one a week either.
