Insert con rod suggestions
We wish to build an OHV B4 , just a very stout street motor ,as we sure know our way around a flathead v8 well B4s are new to us. What are folks thoughts on a preference to new insert con rods as to a particular brand. We have a decent cam from Jim Brierly , a good B4 block, unsure yet wether we will used the good counterweighted crank or pop for a new one. Pistons are allo in the information gathering zone.
We have a new Steve Serr head. |

Re: Insert con rod suggestions
I have had good service from Antique Engine Rebuilding (AER) inserted rods on many engines. Mostly mild but a few hot A's and B's were built and are providing good service with these AER rods.
Straying from your question: Please keep this forum updated as to your progress with the Serr head. I, for one, am very interested in your progress and end result. A Serr topped B is a project I would like to start. Thanks Good Day! |

Re: Insert con rod suggestions
Ross racing pistons have thinner rings,better oil seal.
If you don't plan on racing then a lot of the lower end upgrades are not needed,babbit works well,early B crank too..weld on counterweights if you want,but an early B crank with a harmonic balancer will work.Full pressure oiling,fancy rods,counterbalanced cross drilled cranks in street driven cars are a waste of money in my opinion. Well balanced stock lower end components fills the bill. Even with the Serr head you probably wont spin the engine near 3k..torque flattens out at around 2500.Compression at 6.5 to 1 or so. The cragar head,which Serr based his head on,was a highly successful OHV conversion to a stock model a engine.Even in a high load application like trucks the engine held up well. They key words here are stock..A crank,A rods,heavy flywheel,stock cam..on babbitt. |
