Motor's F'd up...so I'm building a stroker

NO SLO PK · 06-26-2004, 10:48 PM

Tear down of my motor showed #7 and #8 pistons were slamming the head. Rather than rebuilding, I decided to go with a 331.

I'm building this one myself to save $. The new motor has a Scat cast crank, 4340 I beam rods, Probe dish pistons, and billet main support. I was worried about using a cast crank, but everyone is saying it will outlive the stock block.

It's costing me $600 more than a 306. It's mostly for a new 28 oz. balancer and flywheel. So $600 for 30+ hp? That's only $20 per hp, which is cheap hp.

All the parts are in my garage waiting for assembly and I can barely wait to get it running. I had traction problems before...guess it will be worse now.

Looking at your other rides, I would think you would be used to traction problems. J/K

Have fun with the stroker build-up. I think you'll love a blown 331.

SCAT makes some great stuff from what I hear.

Keep us posted on the build-up.

Scat's quality on the cast stuff is hard to beat. IMO, Eagle makes a better forged assembly...it's zero balance which reduces stress on bearings, etc.

So, a lot of parts are coming from Summit and should be on my doorstep by Friday. The shortblock should be done by this weekend. The file-to-fit rings will probably require the most time, but I'm trying hard not to rush things.

Dave, my worse car for traction is the 5.0, lol.

I`m not supprised, my combo looks very similar to yours.
