408 stroker 8-71 blower e85...teach me

I agree that the procharger probably makes more sense than the roots style blower but if that's what you want, go for it. I have no experience with a roots style blower but I think I'll go down that road someday on a different build.

My 408 is 9.0:1 compression and I run 10 lbs of boost with my procharger. I run water/meth injection to cool the air charge. If you run too much timing you will blow holes in your pistons... ask me how I know :)

I was told by tons of people I'd be able to run 30 degrees of timing all day long with my combo. I thought I was being conservative so I started out at 27 degrees. It ran like a scalded dog but was detenating but the procharger is so loud you couldn't here it. By the time I got the timing backed down to about 21 degrees it had already blown holes in 6 of the 8 pistons.

Anyway, it's back together now and very happy. It runs 6.20s to 6.40s in the 1/8th depending on the weather. I run a max of 21 degrees timing.

All engines are different, but just be VERY careful with your tune. I personally wouldn't run that much compression with an 8/71 blower. I'm thinking you are better off getting a custom piston.

As everyone has said, making that much power isn't cheap. I've been through a lot of transmissions. My Dana 60 is holding up but transmissions have been the weak link. I'm probably around 700 Horsepower on a stock block. That I'm sure is pushing the limits so I plan to go to an aftermarket block someday. Check out my build thread.

It's very fun to go this fast in a street/strip car, but sometimes I miss my junkyard 5.9 magnum combo that went high 11s and low 12s that was bullet proof and I could and did drive anywhere. That junkyard motor still lives in my buddies 73 cuda.
