thanks everyone for the suggestions! I WAS WRONG..the converter flashed @ 4200.

ron.... they are flat tops w/ valve reliefs so, comp ratio is ?? i do know that it will run on if i run 91 octane.

mopar man...tti 2-1/8th step. i know probably too big, but they fit so good, they are staying.
cam specs attached.

i know there is some more to be had w/ this combo if i super tuned it, it most likely would like more gear and a looser converter, but i drive this thing everywhere rain or shine! i've driven it 2 hours away to brainerd for a test day and then back with no probs. i want to keep alot of that street ability but want to gain more power and torque thru the whole rpm range (this cam i think is limiting torque down low. what do you think??) since the engine pings/ runs on if i run straight 91 pump gas, i figure i should make it funner to drive (since i have to run race gas anyway) so, keep the combos/ideas/critiques coming! i'm all ears



Thats a bummer you have to run race gas. I built a .042 quench in my 906 headed 440 and I run on 92 pump all the time with 38 total timing. I guess mine would run fine on 91 but I never tried it. I also run mine thru the pipes but its a 3" system so it may not go faster uncapped. That race gas can get very pricey. And thats one nice Plymouth you got. Ron
