Default 331 cu. in. Stroker

Well, after debating whether to get a ProCharger or a new motor, the motor has won out. The ProCharger will hopefully come next year or the year after that. Here's what I'm building:

DSS 331 cu. in. stroker kit:

- 4340 Forged Steel Crank 3.25"
- 4340 H-Beam Rods 5.315"
- Twisted Wedge, Flat-Top Pistons (by Coast aka Probe Industries)
- Federal Mogul bearings
- Plasma-moly (ductile-iron) rings (for future blower)
- 7 qt. Canton Deep Sump Oil Pan & pickup
- Melling high volume oil pump
- DSS Main Support System
- DSS Windage Tray
- ARP everything
- 9.1:1 compression

I will be using my stock 39,000 mile block. It will be going to the machine shop this week for hot tanking, checked for cracks, bored, honed, and the kit will be balanced to 28 oz.

Not having any experience with building motors, and not wanting to screw-up and wasting money, I am having the motor built by Fox Builder and his good friend Rich. Rich has built race motors for 18+ years and races in trophy stock class. The motor is being built for future boost, so, although I will be sacrificing power now, it should be a strong running blower motor.

We will be using my Trick Flow TW's which flow 272 on the intake and 206 on the exhaust. My Steeda #19 cam will be re-used as well. Overall lift will be .516"/.516" with 220/226 duration and 115 lobe separation. I have a set of Energy Suspension motor and tranny mounts on order and am in the process of having my JMS chip re-burned for the 331.

We should have everything built and ready to go in 3 weeks or so. I will keep everyone posted on how things progress.
