Not 100% if I'm selling this, just looking at offers for the moment. Make an offer, may be willing to go down in price or trade.

I may have missed it. What pistons and rods? Estimated compression ratio? Who did the machine work and assembly?

 

Stock 4.351" hypereutectic pistons and replacement I-beam rods. Block was only rehoned since 403s are kind of prone to cracking cylinder walls with overboring. Honing was done at a local no-name shop. Current static compression is 8:1 because I was planning on running a good amount of boost through it.

 

Thank you for this information.

 

Which model Comp Cam or failing that, what are the duration numbers @0.050 and LSA?
