Hey guys I have a model 40 Briggs I am rebuilding right now I am curious what you guys are running for connecting rods mine is a built engine with stocks rods I believe I am curious if the billet rods are worth the money or if stock ones are good to go

Unless you want a ventilated block I would put billet rods in it. Stockers are only good to 3650 rpm's.

Lol alright thanks for the reply I believe they are stock rods I took out of it someone before me built the motor has a lot of good parts are the stock rods aluminum ? The don?t say any name on them but there is what looks like a Briggs logo on the side of them so I?m guessing they are stock

Cast aluminum, the aftermarket like from ARC or EC carb are billet.

Thanks for the reply I have looked at the ec and arc rods and mine are definitely stock it?s kind of crazy someone put a prescion cheetah cam and ec roller rockers and arc aluminum fly wheel on this motor but left the stock connecting rods I got the whole set up second hand I took the motor apart because the key way bent and fell on on the fly wheel so I thought I had blown it up because I lost a cylinder due to that and decided to freshen it up while it was apart
