Just seeing if anyone is interested. I’m building a 331 from a stock block for my 93’ LX. I will be having it dynoed after it’s complete. John Bouchard is building my short block. I’ll finish the top end. If you are interested let me know and I’ll post my parts list and dyno numbers. This may help someone who is trying to decide on parts or cubic inches etc….

I'm very interested in seeing your dyno numbers after it is complete. I'm also interested to see what top end you are using.

The block just got hot tanked Friday (24 Sep). Hopefully get all the machine work done this coming week and short block done by 8 October. I’ll pick up the short block and finish the top end at my house. Hopefully by 15 October get it on the dyno. I can’t wait to hear it for the first time and see how much power it’ll make. I hope to be driving my car again by the end of October.

Edelbrock RPM 2 EFI intake
70 mm throttle body
xe274hr comp cam
1.6 rockers
MAC 1 3/4 short tube headers

Dyno numbers:

I hope so. John thinks it’ll be closer to 500 at the crank. He built a similar 347 with an E 303 plus cam that made 551 crank hp. DSS pistons, TFS 11R 190 heads and E 303 plus cam.
I think you'll hit at least 400 horsepower to the wheels with the 11R heads.

Sounds like a decent combo. Love the 331's. My old one made Great power and ran really good at the track too. until I hurt the crank. #1 main bearing. Still have the rotating assembly as I did not blow it up. Was together for 13 years. I'll put another one together once I get a new crank.
