I have been researching the 408 stroke, people say stroker too much , and i would like to know if any one here has built one. i am using an early 360 block cuz it has the thick sleeves, i just haven't ordered anything cuz i want to keep it on the road not just shows. can you keep it a daily driver? what did it cost? who did you get parts from? pros/cons? how much machine work?

Hello,

I drove a '76 Valiant with a 360 based 408 year round in Wisconsin and IL for years. It had a 4-speed and 4.10's out back. Mopat directed me to this thread however I'm a in the middle of work right now.

I'll answer your questions...stay tuned.

The 408 is now slated to be installed in my '65 4.88 geared W100 by or before 2012 (inside joke for MoPat).

horses/torque? it wasn't trying to jump out from under you in stop and go traffic? what kind of maintenance for daily use?

this is s daily driver this is etsweptsters truck this year his times have been around the 11.50's with no additives, but its now on E85, its his primary source of transportation, its alot more than just stroked

Wondered why I didn't hear from ya yesterday Jeremiah.
I'd hoped it was because you were spending some "QUALITY TIME " with your girlfriend!!
I got the OSB up in the back shop and 1 coat of paint on it.
Maybe TODAY we can get your '65 out of the shop and hosed down so the 408 is 1 step closer to install.

Sorry about the delay...workin 80-90 hours a week is not helping with the spare time factor. I never dyno'd my 408 but it would run in the 12.50's on whitewall snow tires with horrific 60' times. It was not uncommon to have the car loose traction shifting into 3rd or even high gear now and then. I never put a sticky tires under the car because it only had a "spruced up" 8.25, no cage, and was VERY rusty. Ask MoPat how rusty it was! Anyhow, the motor has 308 casting heads that were ported and sports a Doug Herbert roller (258/270ish at ,050, .604/.603 with 1.5's and installed around 108). Lots of people said the cam was too big but I think the short tire and tall gears helped cover up any mismatch. I ran a ported Eddy RPM and a 750 Holley HP carb as well. The car was very interesting on the street. In the snow I would start out in 3rd gear to get traction but it was just fine with 300 lbs of sand in the trunk. As far as daily use I drive my cars pretty hard but do not commute so it's not a very fair comparison. If you plan on putting on some miles I'd stay away from a solid roller. Sorry for the long reply, I'm sure there is something I missed.

SB strokers work great for trucks! Lots of torque! The one I built for my Duster was a 71 360 motor. They will run a little hotter than a shorter stroked motor. Costs are a little higher because you need a stroker crank, new rods (or ones out of a magnum motor), and new pistons. I know guys that daily drive some seriously modified motors. Question is what do you want out of it?
