Default 408 questions

how many ppl are running these motors? if so give your combo and the numbers your seeing along with times. chances are good that im getting this new 408 for a good deal with a custom cam for it. specs read
244/248 612/615 112+2 the combo should be around 11.5 SCR

You will need a 3K or os for that cam sounds like like it will run good in oyur skinny truck. My 237.242 spins all four in my heavy truck so that bigger one should be just fine for your 2wd. Thought oyu just got the stout 6L going?

i already got a 3800 stall so like said before i have the gear and the stall to run this setup.

as for the 6.0 yes its running pretty well untuned but for the price i cant pass this up. less money into this complete new combo then most ppl will have in there radix seutps
as for spinning i destroy 305/40/20s now i know ill be facing less traction with the new motor but when on slicks thats where hopefully it will shine

Was just saying you need a much smaller stall. Use the tq that you willg et from a stroker you cant utilize a 3800 stall and 408 with a 2wd IMO.

Another thing to think about. Are you running a 60E? How well do you think that tranny will hold up behind the stroker?

then you would laugh at the stall that used to behind this motor. it was a 4400 before. im sure i could utilize it with that huge stall but only on slicks
