...at what rpm does your 408 stroker peak / where do you shift?
7000 for me
I'm running a small cam in my 408 and it is great for making power down low and it redlines at 5600
I probably put out more torque at idle then most tuners at redline
Whoa! That torque has got to be some nice street engine. Bet you could run just about any rear with that.Ima thinkin 3.23s with a 2.45low. That would put you at about 65 mph for the 1-2shift. Yummy! I like it!found my sheet
peak torque is 470 ft-lbs at 4000 RPM
peak power is 423 hp at 5400 RPM

comp cams XE268H..What cam are you using in your stroker?
I had a 340 before we built this 360 , wish ihad never got rid of that engine . It was a 69 340 +.030 that would buzz 72 all day long , and like you said it just got stronger . I pounded that motor 25 years without changing anything but oil , plugs and carb . I haven't had this 360 3 years and popped it 2times now with these hyperutectic cast pistons that are supposed to be so nice. talking right now about what is an affordable forged piston and rings for under 600.00 LUV 340"s .Over 7000...rpm for me too..419 still trying to explode it..let u know soon.but I don't think so.:finga:motor is just getting stronger...2500 miles..TNT still
Stock 75 heads, I think they are J castingsWhat heads are you running? Any work done to them?

Mike installed the larger valves in them and I'm sure he massaged them some aswell, but you would have to check with him for details on that
the comp cams k20 227 is a nice 1 need 1.6 rockers thoCan I ask what Dyno this was tested on? Not that I doubt you but the #'s sound high to me. Was there anything else done? what intake? comp? Maybe I am just missing something. sorry no trying to be rude. Have been gathering parts for 408 for a bit now,open intake bowls & gasket matched EQ's, [email protected] .560" roller, modified mopar EFI, big injectors and 1000 cfm TB and my stuff pencils out at 470 HP 475 TQ, I would think there would be a bigger difference or are my numbers low? I cant find any dyno sheets from FI 408 except for chassis dyno w Dakotas. I have built a few of these but never got any dyno time as it was in Portland or Sacramento. They are stupid fast though, guess I need to buy some dyno time now Medford has one
