$1800 and he's gonna build my 46re! He's researching on some torque converters, and said this rebuilt 46re will have no issues handling my 408 stroker. So pumped! He seems like a real honest guy, truly enjoys the work and isn't out to screw anybody over. I'm also getting a one year warranty with the tranny! I'll be putting down a deposit for it next week.
The Mopar performance lifters will be ok in the 408? Also if I do it right, I'll be pulling around 450 hp and 500 tq with the build I've planned out. Engine is getting moved to a friend's heated shop for winter.

So if I were to add a supercharger or turbo, my compression ratio needs to be lower. There are many things that affect compression, combustion chamber size being one. So as of now I believe my compression ratio is between 9.5-10. if I were to go with a larger combustion chamber and lower the ratio, I could possibly use the same cam and pistons and add some forced induction? Just having thoughts lol

My landlord has headstuds that he said I could use if I ever needed.. so I'm almost think of getting these combustion Chambers bigger to lower my compression ratio a bit so I can safely run some boost. To be honest, there isn't a lot of options for fuel injected magnums.. I could obviously go with different pistons and stroke, but that would mean disassembling what I already have done. Which of the two, turbo or blower, would be best for my engine?
so far my engine and how ive planned it is..
Already Done:
block bored .030 over painted hemi orange with 0deck height
Eagle stroker kit that includes 4 inch stroke with i beam rods, -28cc inv dome forged aluminum pistons
226-230 duration@50 555/.565 lift with 1.6 rocker ratio 110 LSA Hughes cam
Double roller timing chain
Lifters waiting to be dropped in
Melling oil pump not sure of the brand of oil pan but is rear sump
Dropped distributor gear in
My plan for the rest:
IMM machined EQ heads 2.02/1.60 intake/exhaust that include vavles with seat job done and springs allowing .625 lift hardened pushrods with 60-62 cc combustion chamber(maybe 72cc depending on if blower/turbo will be good with that)
harland roller rockers
Eddie airgap with big gulp throttle body from hughes
30# injectors(subject to change)
Turbo?
Or supercharger?
