I Need A Shrink !

Strick,

Looking forward to seeing what amazing stuff you'll do with this one! Personally, I'd either keep the 350 or go with a big block.

The sb chevy has fairly short rods and when you increase the stroke, it creates angularity problems (puts more side load on the piston because of the different geometry). Yes, it'll make more power, but I think you'd take a hit in durability.

A good friend of mine had a single 350 Mercruiser in a 27 SeaCraft flybridge sedan cruiser, and went to a 400 sb to get more power out of the same size installation. After 300 hrs it was using a lot of oil and smoking bad, so he tore it down . . . every single piston was cracked! He then put in a single 454, and said it was great, no more durability problems. Said the only thing better was TWO of 'em, so he later bought a 28 Bertram with TWO 454's in it!
